So-called supermartensitic stainless steels are a modern type that displays high strength, low-temperature toughness and acceptable corrosion resistance.

Pen shows are back on the schedule in the US. For how long? Who can really say at this point. I’ve missed attending them, that’s for sure, because the memories made at these events are worth more than any pen or ink or paper that I bring home.

This is the most common type of stainless steel. In addition to 16-25% of chromium, it contains nickel and sometimes nitrogen in solution.  Austenitic steel is is nonmagnetic, extremely formable and weldable. It is also characterized by low proof strength, strong work hardening and very high ductility.

Magnetic alloys are complex alloys. The high-nickel magnetic alloys exhibit high initial permeability and fairly low saturation induction while soft magnetic nickel-iron alloys are used in switchgear and for direct current motors and generators.

Low expansion alloys are nickel-iron alloys exhibit low and constant expansion coefficient over a particular temperature range. They are used in medical, scientific and automotive industries to manufacture precision instruments, scientific instruments, laboratory devices, motor valves, aircraft industry parts and electronic parts.

I had just seen Ian at the Philadelphia Pen Show five weeks prior, and even got to tour his workshop as part of a group during that event. The Pocket Six had recently been launched, and I made sure to purchase my second one, with the newly-added Jowo nib compatible grip section.

I see a lot of pens for the first time at pen shows, so why does this one stick out more than most? Well, have you seen it? That’s what people kept telling me as they were bringing them over to me see at the 2020 Baltimore Pen Show - aka the last pen show I attended in person.

Ferritic grades demonstrate high corrosion and oxidation resistance, in addition to being highly resistant to stress corrosion cracking. These magnetic steels contain no nickel and cannot be strengthened by heat treatment. They also exhibit low proof strength, limited work hardening and decreased ductility at high chromium levels. Ferritic grades are widely used in homes (sinks, decorative trims) as well as in transport (car exhaust system).

In general, nickel alloys can be divided into the following two categories: nickel-copper alloys and nickel-chromium base alloys.

Applications of stainless steel and nickel alloys include various industries, such as construction, transport, architecture, food and beverage handling (cookware), medical equipment and pharmaceutical industry. Both kinds of alloys are also used to produce military parts, marine products, jewelry as well as industrial and petrochemical parts.

Posting is key for pocket pens, and the Pocket Six design handles that with threads on the end of the barrel to attach the cap to. It takes less than two turns to uncap the pen, and then the same amount to post, so it is a relatively fast process.

Martensitic grades of stainless steel contain a relatively high amount of carbon in addition to 12-18% chromium. They are hardenable by tampering and quenching and can be subject to heat treatment in order to improve their properties. Depending on the type of heat treatment, these grades can also exhibit high ultimate tensile strength in addition to low elongation to fracture.

2. The other group of nickel-chromium alloys contains significantly more nickel (70-80%). Their applications include resistance heating elements exposed to temperatures up to 2102°F (1150 °C).

Nickelalloysteel

Stainless steel is a generic term used to describe a variety of steel types and grades that provide high corrosion and oxidation resistance. In general, stainless steels contain iron and a minimum of 10.5% chromium. Of other alloying elements, the most important one is nickel.

Exterior design aside, the Pocket Six is an excellent pocket-sized fountain pen. As good as any on the market, especially since it is built around a #6 sized nib. I love my #5 nibs, as found in Kaweco Classics and Sports, but using a #6 nib is an upgrade across the board.

Nickel-copper alloys are also known as Monel alloys. In addition to nickel, they contain 29-33% copper as well as small amounts of iron and manganese. The main properties of nickel-copper alloys include high corrosion resistance, great mechanical strength, good ductility and a low coefficient of thermal expansion. However, they do tend to quickly work-harden.

Stainless steel alloys represent the largest single first use of nickel. The addition of this silvery-white, hard and ductile metal gives stainless steel high corrosion resistance, ease of production, high formability and good weldability.

Nickelalloycomposition

Why do I bring this up at the beginning of this review? Because a pen show is where I first saw the Schon DSGN Pocket Six Faceted Brass Fountain Pen.

Stainless steel is a steel alloy that contains chromium. In addition, it may also contain other elements such as nickel, carbon, manganese, molybdenum, nitrogen, copper, titanium, phosphorus, sulfur, selenium, niobium, silicon, cobalt and calcium. As a manufacturing metal, stainless steel provides a number of desirable qualities, including corrosion resistance, strength and relatively high-temperature resistance. It is usually shaped into castings, forgings or extrusions.

Duplex grades are essentially a ferritic-austentic stainless steel combination. They contain more than 20% chromium in addition to small amounts of nickel and molybdenum. This composition gives them good resistance to corrosion and stress corrosion cracking, good abrasion and corrosion resistance, high mechanical strength, high energy absorption as well as low thermal expansion and good weldability. The many applications of duplex stainless steel include paper industry, pipe systems in chemical tankers, seawater systems, firewalls, bridges, storage tanks, heat exchangers, water heaters, structural design components and more.

Nickel-chromium alloys provide resistance to oxidation and metal failure through a loss of strength that often occurs at high temperatures (with the exception of high-temperature sulfur-rich environments). Thanks to their excellent resistance to acid, alkalis, water and seawater, oxidation, flammability, and organic solvents, nickel-chromium alloys are usually applied where particular heat and corrosion resistance is required.

This pen represented a big change in the Schon DSGN lineup. The pen bodies had always been minimally styled, with the addition of wild anodizing taking the pens up a notch in the recent years. But to modify the base cylinder with a design as complex as these facets? Well, these just jumped off the table when people saw them in Baltimore, and quickly made their way over to me.

Is it worth it? It depends on what you feel about the aesthetic. It is a true step up in looks from the base model, but exactly the same from a performance perspective. Regardless of the model you choose, I guarantee you will come away impressed with the work of Ian Schon.

Nickelalloyproperties

The more recent nickel-chromium base alloys contain a variety of ancillary elements, the addition of which creates new and improved alloy properties.

Fast-forward those handful of weeks to Baltimore, where I had brought Nock Co. to put in some hours behind the table, instead of mixing and mingling, as I did in Philly. Knowing my love for Schon DSGN pens, my “friends” started appearing at my table with their latest purchase that they couldn’t wait to show me. Yes, this very bright, shiny, and beautiful faceted brass Pocket 6. Ian had been very busy since I last saw him!

I didn’t have the opportunity to grab one at the time, but Ian was kind enough to send me one later to review. If you couldn’t tell by now, I like the pen.

1. The first group includes cast alloys that contain 40-50% nickel and 50-60% chrome. These alloys are heat and corrosion resistant. Their applications include structural parts, containers, supports, hangers, spacers etc. that are exposed to temperatures up to 1994 °F (1090 °C).

All of that said, it is the machined faceting that makes the Pocket Six pop. I love the design, and the end result makes for a stunning pen. This design doesn’t come cheap, though, starting at $250 for the faceted model, versus $142 for the standard polished brass.

The choice of a particular stainless steel alloy and grade relies largely upon corrosion resistance requirements. Various mechanical and physical properties of stainless steels should also be considered to achieve particular service performance requirements.

In general, nickel-copper alloys are used where a higher strength is required compared to pure nickel. Because of their superb resistance to acids and alkalis, they are frequently used in chemical plant equipment. With small additions of aluminum and titanium, Monel alloys can also be used in the aerospace industry. Other common applications include valve stems, heat exchangers, screw machine products, piping systems, fuel and water tanks, kitchen sinks and more.
