Stainless Steel, Precipitation Hardening3S144 (S144) Bar

Aerospace stainless steel heat treated to provide extra tensile strength.

S144 is a British aerospace grade, precipitation hardenable stainless steel. It is widely used in the aerospace industry benefiting from a combination of strength and moderate corrosion resistance.

The alloy has an identical chemical composition when compared to S143 but a higher tensile strength is achieved as a result of heat treatment.
