Product Description
DIN 25CrMoS4/1.7213 QT Alloy Structrural Steel
1: 25CrMoS4 Steel Introduction
25CrMoS4 Steel is defined as a low alloy steel which contains 1%Cr and 0.2%Mo as strengthening alloy elements. it offers good strength, toughness, corrosion resistance and machinability. Compared with AISI 4140, It has lower carbon,0.28-0.33%, so it can be welded easily. 25CrMoS4 Steel is commonly supplied in the hardened and tempered condition with a hardness range 207-235HB.
