Description
Material Short Introduction:
ASTM A182 is Material Standard Specification for Forged Stainless Steel Pipe Flanges and Stainless Steel Forged Fittings. AISI 321 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 solution annealed condition.
Applications:
Commonly used in industries such as offshore, marine, food, paper mills, oil field and aerospace.AISI 321 is used for components such as fasteners, couplings, screws, bushings, studs, fittings, valve stems, roller, wear rings.
