Steel 17-22A(S) AMS 6302

Steel 17-22A(S) AMS 6302

AMS 6302 is a specification of Steel 17-22A(S), which is ultra-high-strength low alloy steel with a high percentage of Carbon, Molybdenum, Vanadium, and Chromium. Its main characteristics are excellent high-temperature strength and high heat resistance.

This sub-type specification of Steel 17-22A(S) is available as bar, forging and tubing and possesses excellent machinability and toughness. It is mainly used for manufacturing of shafts, studs, and fasteners, mechanical parts in aviation, mechanical parts in engines, steam turbines, industrial furnaces, guided missiles, turbine rotors, and petrochemical engineering operations.

Recommended heat treatment for AMS 6302 starts with normalizing at a temperature of 1700-1850°F (926-1010°C) and holding for one hour for each inch of thickness. Then the part is air cooled or fan cooled if the process is to be accelerated. Please note that all surfaces of the part must have access to air for even cooling.

After normalizing, annealing is done at 1450°F (787°C) for one hour per inch of thickness to get to 1100°F (593°C). Additional hardening can be achieved by oil quenching at a temperature of 1750°F (955°C).

The AMS 6302 specification can be welded using all popular welding processes. The use of a welding wire with the AMS 6458 specification is recommended.
