Exhaust systems, fuel lines, and other automotive parts use stainless steel because they are durable and corrosion-resistant.

Numerous elements, including feed rate, speeds, and cutting tools, can cause a workpiece to deform. Increasing tool deflection while utilizing a worn cutting tool would make pieces out of tolerance and distorted. This is why it’s crucial to machine stainless steel at the proper speed and feed rate.

Gustavus Hinrichs can lay claim to the first periodic spiral. In fact, the German chemist proposed the design in 1867 – two years before Mandeleev’s table – with elements arranged based on mass (figure 3). But the Hinrichs spiral showed primary relationships between the elements and lacks the detail of later versions.

In 1935, Emil Zmaczynski was one of the many to think outside of the tabular format with his periodic triangle, which graphically represents the process of constructing electron shells for atoms (figure 2).

Just as Mendeleev wasn’t the last to arrange the chemical elements, he wasn’t the first. Frenchman Alexandre-Émile Béguyer de Chancourtois can claim this feat, having arranged the elements in order of atomic weight in 1862 (figure 1).

In celebration of the International Year of the Periodic Table, we decided to tip our hat to some of the more unusual, obscure and overlooked periodic designs.

Due to their sanitary qualities and corrosion resistance, free-machining stainless steel components are used in processing machinery, storage tanks, and other applications in the food and beverage sector.

Timothy Stowe’s 3D chart was specifically designed for physicists, geometrically showing energy levels within an atom (figure 7). The three axes represent principal, spin and magnetic quantum numbers, while colours represent different values of the angular momentum quantum number.

Stainless steel, also 400 series, is utilized frequently in the production of machining tools due to its excellent toughness and outstanding corrosion resistance.

Due to its excellent corrosion resistance caused by seawater and other hostile environments, stainless steel is frequently utilized in marine applications.

Martensitic stainless steel was named after Adolf Martens. These steels are renowned for their extraordinarily high toughness. These steels must undergo aging and heat treatments for high hardness and tempering.

Some of the operations are grinding, drilling, or turning. The computerized control of the CNC machine ensures repeatable, dependable operations that produce components with high accuracy and fewer mistakes.

The stainless steel color is silver-white and does not tarnish or corrode with time. Chromium in large amounts is what gives it its look. Apart from strength, stainless steel also has other characteristics. Because of its lovely appearance, this metal is used in many different items. CNC-machined stainless steel parts have a clear, contemporary look without losing functionality.

Blogger Mitch Fincher created the Mayan Periodic Chart in the early 1990s, taking inspiration from the Mesoamerican calendar (figure 6). The psychedelic ring is made of concentric circles, each containing elements ordered according to their atomic number.

Examples of duplex stainless steel are X2CrNiN22-2, X2CrCuNiN23-2-2, X2CrNiMoSi18-5-3, X2CrMnNiMoN21-5-3, X2CrNiMoCuN25-6-3, and X2CrNiCuN23-4.

“I thought the spiral had more potential to show the interrelations of the elements than the Periodic Table,” he said. “The arrangement could get at the underlying philosophy as to why some elements attract other elements, why some are useful in conversion and why some are useful for protection.”

It can have a low or high carbon quality. Examples of martensitic stainless steels are X12Cr13, X20Cr30, X50CrMoV15, and X17CrNi16-2.

But within 100 years of the appearance of Mendeleev’s Periodic Table, it is thought that around 700 different versions were published, all taking many shapes and forms in different dimensions, from spirals, cylinders and rings, to fractals and pyramids.

Ferritic stainless steel was discovered in 1912. However, it didn’t become known and considered for various applications until about 1980. They belong to the family of AISI 400.

Achieving optimal results and maximizing productivity in stainless steel CNC machining requires specialized tools and equipment tailored to handle this durable material. These are some of the essential tools and equipment needed for CNC machining for stainless steel:

Fincher told Laboratory News: “The Mayan Periodic chart came to me about 30 years ago while trying to create a three dimensional periodic table. I came up with the idea of concentric circles representing electron shells after pondering the lack of symmetry in the traditional one.

“I saw in a dream a table where all the elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper.”

Groups of elements are all arranged in different colours, including the noble gases, which are in a vertical column through the centre. What’s neat about the ring is that the more stable elements are on one side of the noble gases, and the least stable are on the other. Transition elements are integrated with all the other elements.

Numerous industries use stainless steel because it is durable and resistant to corrosion. However, CNC machining is a flexible and cutting-edge technique for producing intricate stainless steel machined parts with great precision.

Medical items such as implants, surgical instruments, and other devices frequently need the precision and accuracy that stainless steel CNC machining can offer.

The stainless steel CNC machining process starts with producing a compute-aided or digital design model of the desired parts. CAM (Computer-Aided Manufacturing) software then converts this design into code machines can read.

Stainless steels that precipitation harden can yield strengths 3–4 times greater than those of austenitic stainless steels. An example of PH stainless steel alloy is 17-4 PH Steel.

One method of controlling chip formation in machining is pecking and chip-breaking cycles. This helps get rid of lengthy, stringy chips. Checking tools frequently is another technique to control chip formation because chip production is increased by worn cutting tools.

It is advisable to use high-quality tools, such as drills and end mills made of tungsten or molybdenum HSS. They can resist the strain of the process when cutting stainless steel with little wear. These devices also enhance surface quality. Use durable tools sparingly because doing so could slow down machining and raise manufacturing expenses.

Stainless steel is a versatile and common material in many industries. Durability, high strength, and corrosion resistance are just a few of its excellent attributes. CNC machining creates intricate and precise stainless steel components through computerized automation.

What’s interesting about Stowe is he his apparently untraceable, vanished from the scientific community. His table was discovered and republished by Instruments Research and Industry in 1989.

One hundred and fifty years later, Mendeleev’s table is used every day in labs, classrooms and institutions across the world. Usually, when we think of the elements, we picture them in the tabular format of which Mendeleev had the original idea.

The structural design of duplex steel consists of two parts. It combines ferritic and austenitic stainless steel resulting in duplex alloys. These two essential structural components are enhanced by duplex steel alloy. This stainless steel is available in three grades: normal, super duplex, and lean duplex alloys.

Stainless steel alloy has good corrosion resistance and can resist rust and water stains. Stainless steel is perfect for indoor and outdoor applications because of its corrosion resistance. Due to the presence of chromium in the metal, which creates a thin layer to protect the steel when it comes into contact with oxygen, stainless steel possesses this feature.

In 1949, Life Magazine published a somewhat more fleshed out spiral, or rather part spiral, part Olympic racing track. Elements are arranged based on number of electrons, starting with hydrogen in the middle. The magazine said: “The colours and construction of the table express another kind of relationship among the elements: the repetition, at regular intervals, of the chemical properties of the first few.”

After grade 304, grade 316 is the most widely used and standard. 316 contains molybdenum, which increases its capacity to resist corrosion above grade 304. Additionally, 316 has good forming and welding properties, contributing to its popularity as a machining grade.

Some may find Stowe and Tsimmerman’s tables difficult to comprehend, however, and for a quick reference may want to look elsewhere.

Many of the redesigns of Mendeleev’s table down the years have ditched the grid in favour of a spiral. One of the benefits of such a design over the tabular form is that it glues together the split that occurs at each end of the table, thus connecting elements at either end that potentially have similar characteristics.

Continuing along the quantum zone, Valery Tsimmerman’s ADOMAH periodic table from 2006 is effectively two tables in one (figure 8). The numbers at the bottom of the table either represent quantum number n as you follow the vertical rows, or n+l if you follow the 3D-layers.

Stainless steel CNC machining is an accurate and efficient machining process that uses CNC machines to shape, fabricate and cut stainless steel parts.

The CNC machine analyzes the code to activate the accurate movement of the cutting tool and extract material from the stainless workpiece. The CNC machine uses programmed instructions to carry out a variety of operations during the machining process. However, this is dependent on the specification and complexity of the parts.

Unfortunately, when de Chancourtois had his work published, the diagram of his helix was left out, meaning it was somewhat overlooked upon its original publication.

Because it has outstanding forming & welding qualities, grade 304 is the most adaptable and frequently used stainless steel grade in machining tools. 304L has less carbon than 304 and doesn’t require post-welding, and 304H has more carbon than 304. As a result, It offers adequate toughness for machining tools.

This CNC machining material comes in various types. Each of them has unique qualities that suit different requirements. These are some of the common types of stainless steel for CNC machining:

Some stainless steel grades remain stable at a range of temperatures. For instance, austenitic stainless steel alloy displays excellent toughness and enhanced tensile strength at temperatures below zero. Nevertheless, it’s crucial to remember that not all stainless steel grades have this characteristic.

Precipitation Hardening stainless steels can also be called PH stainless steel alloys. These alloys contain trace amounts of other substances, such as titanium, copper, phosphorus, or aluminum. These steels go through an age-hardening process after alloy production.

In March 1869, Russian scientist Dmitri Mendeleev arranged all known chemical elements into a table, in rows of atomic number from left to right. Mendeleev wrote in his diary:

A more recent iteration, software developer Jeff Moran’s version tries to better illustrate hydrogen’s relationship with multiple elements, again by putting it at the centre (figure 5).

Stainless steel has a greater tensile strength than mild steel, brass, and aluminum alloys. The tension required to stretch a material to its breaking point is known as tensile strength. This is an essential quality for many products throughout their useful lives, especially for parts that would undergo a lot of bending and rolling.

De Chancourtois, a geologist, drew the elements around a metal cylinder, with similar elements – such as alkali metals lithium, sodium and potassium – lined up vertically. He called his creation “telluric helix” because tellurium was placed in the middle.

Some of the designers responsible for these new versions thought the tabular form had limitations that they wanted to improve upon; others wanted to make the elements easier to comprehend or accommodate for new discoveries. Others still just wanted to create informative art that would look great on their wall. Let’s take a look at some of the most memorable versions.

With an easy to follow structure and colour coding, Benfey’s spiral or “snail”, illustrates the elements in a more engaging way. Each colour represents a group of elements and each spiral represents a period on the traditional periodic table. Atomic numbers and masses are notably absent, however.
