DIN 10088-1 Technical specifications of W-Nr 1.4577 austenitic stainless steel, Round bar, flat bar, plate, rod from steelmaking, hot forging, rolling, heat treatment
TECHNICAL DATA SHEET - X3CrNiMoTi25-25 & W-Nr 1.4577
MATERIAL CATEGORY: Austenitic corrosion resisting steels
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / VOD 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 bright in the annealed condition.
Final heat treatment - QT.
