440 Stainless Round Bar Stock

440 stainless bar stock is martensitic in a structure whose chemical compositions consist of the following: 16-18% chromium, 1% manganese, 1% silicon, 0.75% molybdenum, 0.04% phosphorus, 0.03% sulfur, and some percentage of carbon.

440 stainless round bar stock that can attain the highest hardness levels

440 stainless round bar stock or better known as ‘razor blade steel’, is high-carbon chromium steel that when put under heat treatment can attain the highest hardness levels compared to any grade of stainless steel. The applications of 440 stainless bar stock steel are the following pivot pins, dental and surgical instruments, high-quality knife blades, valve seats, nozzles, oil pumps, and rolling element bearings. 440 stainless bar stock is martensitic in a structure whose chemical compositions consist of the following: 16-18% chromium, 1% manganese, 1% silicon, 0.75% molybdenum, 0.04% phosphorus, 0.03% sulfur, and some percentage of carbon. This metal is hardenable which means that it gains an additional strength through heat treatment making them both abrasion-resistant as well as corrosion-resistant. Although if there’s ever a downside to the material, it’s that 440 bars of steel do not work well at extreme temperatures, as high temperatures may lead to the material losing its strength; they also lose their ductility when at a temperature that is below 0C.
