NV A500 steel grade.
NV A500 is applied to extra high strength steels, which is defined as steel with specified min yield stress of 420Mpa. The max yield is 690Mpa in NV A690.
NV A500 steel grade shall be killed and find grain treated. Steel grade of strength levels up to and including 500Mpa should be supplied in Normalized, TM or QT condition. Steel grade of strength levels above 500Mpa shall be supplied in TM or QT delivery condition.
Gangsteel is specialized in Super thickness steel grade. We have much experience in manufacture and exporting extra high strength steel grade.
