BS S80 Stainless Steel BarBS S80D - Bright

Stainless Steel Bar

BS S80 is a 16% chromium stainless steel modified by the addition of nickel, in the British Standard Aerospace series of alloys.

It is designed to develop high mechanical properties by conventional heat treatment methods and provide good corrosion resistance. This grade is manufactured by electric melting process. It is magnetic in all conditions and can therefore be used for parts which may be subject to magnetic inspection. The designation BS S80D denotes material in the hardened and tempered condition.

Machinability & Formability:

BS S80 has better machining characteristics than the chromium-nickel grades. It has a machinability rating of 45%, with 1212 rated 100%. Surface cutting speed on automatic screw machines is approximately 75 ft/min. This material can be cold formed. If a cold forming operation is undertaken then a stress relieving treatment should be applied.

Corrosion Resistance:

The corrosion resistance of BS S80 is superior to that of the standard chromium grades such as Types 410 and 416. This grade has excellent resistance to corrosion in all conditions of heat treatment from mild acids and alkalis, neutral and basic salts, food acids, and atmosphere. Maximum resistance is obtained by hardening and polishing.
