Description AISI 446 Round bar Stock, AISI 446 Blooming, Hot forging, Hot rolling, Heat treatment, Straightening, 100% Ultrasonic flaw detection test, Cold working or machined.
MATERIAL TECHNICAL DATA SHEET - Grade AISI 446
MATERIAL CATEGORY - 25Cr-N 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
