DIN 10085-5 Technical specifications of DIN 1.4432 Austenitic stainless steel, X2CrNiMo17-12-3 Round bar, Flat bar 1.4432 Forging, rolling, heat treatment.
MATERIAL DATA SHEET - DIN X2CrNiMo17-12-3 & W-Nr 1.4432
MATERIAL CATEGORY - Austenitic corrosion resisting steels
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / VOD / VIM followed by electroslag refining (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.
Bars are usually supplied black/bright in the annealed condition.
Final heat treatment - solution treatment / Q+T.
