BS S143 Stainless Steel BarBS S143

Stainless Steel Bar

This aerospace grade precipitation hardening stainless steel combines high mechanical strength with moderate to good corrosion resistance in a variety of media.

The steel is melted in air by an electric process. BS S143 is similar in a number of respects to 17/4 PH stainless steel (UNS S17400 / AISI 630) in its combination of properties. BS S143 stainless steel is supplied in the fully heat treated condition (solution heat treated followed by a two stage precipitation hardening treatment) as bright bar (BS S143D), black bar (BS S143B) and forgings (BS S143C).

Material to BS S144 and BS S145 shares a common chemical composition with BS S143. Therefore material to BS S143 can be precipitation hardened using a different sequence of temperatures to produce material meeting the mechanical property requirements of BS S144 or BS S145.

Key Features:

S143 Aerospace Stainless Steel Bar provides useful corrosion resistance in mildly/moderate corrosion environments and is similar to that of basic 300 series stainless steels. The machining and welding of this grade of stainless steel presents no particular problems
