Principal Design Features		This alloy is a martensitic stainless that combines corrosion resistance similar to 304, easy fabrication and single step age hardenability yielding good strength and ductility. It possesses a yield strength that is roughly 3 times the strength of standard 304 stainless.

Applications		Generally employed in applications where standard austenitics fail in terms of strength requirements in corrosive environments and martensitics fail in terms of corrosion resistance. It effectively brings together the best of both worlds.

Machinability		Utilize speeds and feeds comparable with other martensitic stainless steels. Positive feeds and slow speeds will yield best results.

Welding		In an effort to minimize contamination, it is recommended that shielded methods be employed.

Hot Working		Soak material at 2100-2150 F(1150-1177 C), air cool after working and fully anneal.

Cold Working		With a relatively low work hardening rate, this alloy may be effectively cold worked using most common methods.

Annealing		Soak thoroughly at 1875-7925 F(1024-1052 C) for 1 hour, water or oil quench.

Aging		To obtain condition H900, H950, H1000, H1050 or H1150, soak material at desired temperature for 4 hours and air cool.
