BS S143 Stainless Steel Bar

Similar to 300 series stainless steels.


BS S143 finds typical use in aerospace and defence engineering and high technology mechanical applications.

BS S143 stainless steel bars provide high strength and good toughness.


BS S143 is a precipitation hardening stainless steel and a BS aerospace-grade that combines moderate to good corrosion resistance and high mechanical strength in various applications.

The alloy offers moderate to good corrosion resistance in various atmospheres, which is similar to 300 series stainless steels. Welding and machinability of the alloy are not problematic. All BS S143 billets (where practical) are subjected to ultrasonic inspection in compliance with British Standards. As the material shares common chemical composition traits with S144 and S145, the alloy may be precipitation hardened using different temperature ranges to achieve the same mechanical properties of these materials. This material also offers similar property combinations when compared to 17/4PH.
