Description
Introduction:
AMS 5643 is a corrosion resistant grade which is soft and ductile in the solution annealed condition. Medium to high strength, good toughness and strength is obtained by the appropriate ageing treatment. As a martensitic precipitation hardening stainless it is characterised by high tensile strength and high yield strength obtained by solution annealing, followed by a single or double low temperature age hardening treatment. AMS 5643 has corrosive properties comparable to 304 austenitic stainless steel in many environments.
The alloy is usually produced by BEF & AOD followed by electroslag remelting (ESR) / VAR if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
100% Ultrasonic test ASTM E2375 /SAE AMS 2154 /SEP 1923 /GB/T 4162 /EN 10228-3.
Bars are usually supplied black/bright in the annealed condition.
