416R Steel

416R Steel

Steel name: 416R
Diagram No.: 2198
AISI/SAE designation: 416R
Chemical composition in weight %: 0.12% C, 0.40% Si, 0.40% Mn, 0.03% P, 0.13% S, 12.50% Cr, 0.40% Mo
Steel group: Chromium stainless steels
Properties: 416R is a hardenable chromium stainless steel particularly suited for use in high quality precision rifle barrels. This grade has good machinability and, because of closely controlled chemistry and processing techniques, may be machined and lapped to a high finish, which is important for bore accuracy.
Applications: No data
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 416R can be hardened by air cooling or oil quenching from 1750 to 1850°F (954 to 1010°C). When air hardening small or thin sections, a temperature in the upper part of this range should be used. Tempering should be at the proper temperature to give the desired properties as shown below.
Tempering: See the diagram.
