Although stainless steels have good weldability, this property can be achieved by modifying the content of carbon in their alloy. A lowered carbon content with inclusions of nitrogen improves the weldability of the 300 series stainless steel. Having a higher content of carbon in its alloy makes it difficult to weld martensitic grades. Therefore, during the welding of these alloy grades, it is necessary to conduct both a preheat as well as post-weld heat treatment.

A unique product line of external tool holders equipped with an internal coolant – enabling a flow of coolant to the cutting edge. This reduces the temperature of the cutting edge while machining, helping to extend the life span of the tool. Additionally, the coolant fluid aids in removal of the chips during operation – improving the cutting performance.

The polygon shank tool holders of the Quick Change line are designed to be compliant with the ISO 26623-1 standard for toolholding systems. As such, they can be used with any coupling system that is based on the ISO 26623-1 standard, enabling quick & easy tool changes.

Martensitic stainless steels are available on the basis of their chemistry and are further classified into four categories. Grades with Fe-Cr-C Chemistry tend to be wear-resistant and are useful for engineering. Similar to the former are grades with Fe-Cr-Ni-C chemistry. These grades have some carbon content replaced with nickel and exhibit properties such as good casting properties, weldability, and resistance to cavitation erosion. Precipitation hardening grades exhibit properties like high strength and good toughness, whereas Creep-resisting Martensitic stainless steel grades are produced with trace quantities of elements like niobium, vanadium, boron, and cobalt. By adding these elements, there is an increase in the mechanical strength, with creep resistance up to a temperature of 650 °C. The austenitic class can further be segregated into two more categories i.e. 200 series and 300 series. While the 300 series are popular, the inclusion of nitrogen in the chemistry of the 200 series gives them an increase of approximately 50% yield strength in comparison to the 300 series.

These carbide shank bars can be used to cut internal threads/grooves. They are especially well-suited for deep small bores with a long overhang, or for use in other situations, where chatter and deflection are expected. These bars have an integrated coolant bore, which helps with chip evacuation. This helps to maximize tool performance, as well as extend the life of the insert.

Tool holders for cutting internal threads/grooves. These holders improve on the basic internal tool holders by adding an integrated coolant bore. The coolant fluid helps to evacuate the chips, which helps to maximize tool performance, as well as extend the life of the insert.

Our industry-leading range of thread turning inserts is recognized worldwide. These high-quality laydown triangular inserts can provide a solution for the majority of the thread standards available today. They can handle a wide range of applications: From the basic, to the most demanding ones.

The partial profile, thread turning inserts that belong to this product line provide a combination of a ground profile insert, and a sintered chip-breaker. Unlike most other manufacturers’ inserts, this combination ensures consistent high quality thread, precise shape, and dimensions – while ensuring the chip flow.

The classification of stainless steel is dependent on its crystalline microstructure. The chemical composition of Stainless steel contains iron. Along with iron, stainless steels also have additions of chromium as well as other elements (nickel, chromium, or molybdenum) in its alloy. The minimum content of chromium in stainless steel is 11%, which keeps it from rusting. The use of chromium in the alloy is what also makes it immune to heat. The microstructure of each class of stainless steel varies with the inclusion of different elements in its chemistry in varying quantities. For instance, the austenite microstructure, which is also in the study of crystallinity of metals is referred to as a face-centered cubic structure. The FCC microstructure is the result of the addition of nickel, nitrogen, or manganese to the alloy. This sort of elemental composition also improves the corrosion resistance properties and mechanical properties of the alloy. On the other hand, the microstructure of martensitic stainless steel is BCT, or what is referred to as body-centered tetragonal. Being a highly strained structure, the chemical composition of the metal has been supersaturated with carbon. Another distinguishing characteristic for both these classes of stainless steels is their property of hardenability, which could be influenced as a result of heat. Austenitic stainless steel alloys cannot be hardened with the use of heat treatment. This is because the microstructure of an austenite variety of stainless steel remains the same i.e. FCC, despite a change in its environmental temperatures. Hence, heat treatments do not work on such alloys. On the other hand, martensitic stainless steel could be easily hardened by the use of heat treatment. Yet, it is this property that makes the alloy less resilient to corrosion as compared to the austenitic class of stainless steel.
