Technical specifications of X2CrNi19-11 Austenitic stainless steel - Chemical composition, mechanical properties from steelmaking, Hot forging, rolling, heat treatment
TECHNICAL DATA SHEET - X2CrNi19-11 & W-Nr 1.4306
MATERIAL CATEGORY - Austenitic corrosion resisting steels
PRODUCT DESCRIPTION
The alloy X2CrNi19-11 is usually produced by AOD / EAF followed by electroslag refining (ESR) / VAR if necessary for special purpose.
Bars and, where applicable, forare 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.
