AISI 504
2014-10-28 09:23:05 Origin： Remark：0 Click：
ASTM A959 Technical specification of AISI 504 is 9.0% Chromium Base martensitic steel, AISI 504 Round bar, flat bar, and forgings, rolling, heat treatment, cold working.
RAW MATERIAL TECHNICAL DATA SHEET - Grade AISI 504 & UNS S50400
MATERIAL CATEGORY: Martensite type 9Cr-1Mo
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
