TECHNICAL DATA SHEET - Alloy Steel - XM-27 / UNS S44627 ROUND BAR, FLAT BAR, PLATE, MATERIAL CATEGORY 26Cr-1Mo Ferrite type
TECHNICAL DATA SHEET - XM-27 & S44627
MATERIAL CATEGORY: 26Cr-1Mo 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 - solution treatment / QT
