Description
AMS 5631 / UNS S44002 is a high carbon martensitic stainless steel. This alloy can be heat treated to extremely high hardnesses. It has slightly less carbon than 440B and 440C giving it better machinability but less hardness. The combination of good wear resistance and high hardness makes this alloy an excellent candidate for cutting tools and knife blades. It also is often used for dental and surgical equipment.
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.
