Technical specifications 1.4477 Duplex stainless steel, Round bar X2CrNiMoN29-7-2 Flat bar, S32906
Hot rolling, Heat treatment, cold working.
MATERIAL DATA SHEET - DIN X2CrNiMoN29-7-2 / W-Nr 1.4477
MATERIAL CATEGORY - Austenitic-ferritic 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 solution annealed condition.
Final heat treatment - solution treatment.
