Description
Technical Data Sheet
S321904 / XM-11 has a moderately high electrical conductivity and can have a moderately high tensile strength among wrought austenitic stainless steels.
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.
