Description
Introduction:
AISI 422 Se 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.
Applications:
Commonly used in industries such as offshore, marine, food, paper mills, oil field and aerospace.AISI 422 Se is used for components such as fasteners, couplings, screws, bushings, studs, fittings, valve stems, roller, wear rings.
