Alloy Steel S44401 MATERIAL CATEGORY 18Cr-2Mo Ferritic Stainless Steel, S44401 round bar, Flat bar, Plate Stock available
RAW MATERIAL DATA SHEET - UNS S44401
MATERIAL CATEGORY: 18Cr-2Mo Ferrite type
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / VOD / EAF 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 - QT.
