Material specification DIN 10088-1 duplex steel 1.4410 round bar, flat bar, rod, sheet - steelmaking, ESR, hot bloomed, forged, rolled, heat treated, cold machined
TECHNICAL DATA SHEET - EN 1.4410
MATERIAL CATEGORY: austenitic - ferrite steel
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 in hot forging or rolling condition.
Final heat treatment - solution treated.
