BSS80D(Bright) TechnicalDatasheet Service.Quality.Value. TypicalApplications Machinability/Formability Used where higher mechanical properties than 410 are required and where corrosive conditions are not too severe. Typically: valve parts, centrifuge bowls, chemical equipment, bolts and screws, in aerospace, defence and high technology markets. ProductDescription 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 S80D denotes material in the hardened and tempered condition.

StainlessSteelBar CorrosionResistance 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. Weldability May be welded by all the commercial processes except forge or hammer welding. Large sections should be preheated prior to welding. Because of air-hardening properties, this grade should be annealed after welding. RelatedSpecifications
