Specifications

Chemical Composition – This is martensitic steel, meaning it can be tested nondestructively and has high hardness. Despite these two characteristics, they have lower corrosion resistance than austenitic steels. In conclusion, they have low ductility at sub-zero temperatures and higher strengths with over-tampering.

Corrosion Resistance – Good corrosion resistance to inhibit rusting, which also helps to minimize fouling. 416R provides the right chemistry to be used in the firearms industry. Being Stainless steel, it will be able to hold up to the stress of firing bullets. Furthermore, it can withstand the hot flashes of gunpowder.

Machinability – Material has been stress relieved and straightened to guarantee good machinability for gun drilling and reaming, which is necessary to maintain bore accuracy. The microstructure responds to heat treating, which gives this material a uniform core hardness along the length of the bar. The material is heat-treated to HRC 26 -32; special HRC requirements can be met upon request. Stainless Shapes provides its 416R with a durable finish that does not pit when properly maintained. Furthermore, 416R offers poor weldability but can be carried by preheating to 400-572 and stress relieved to 1200.
