Description
W-Nr 1.7242 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. W-Nr 1.7242 is used for components such as fasteners, couplings, screws, bushings, studs, fittings, valve stems, roller, wear rings.
