Description

AISI 4140 Scm440 42CrMo4 1.7225 QT Hot Rolled Forged Steel Alloy Round Bar OD 260mm

1: AISI 4140 steel introduction
AISI 4140 is defined as a low alloy steel which has 1% Cr-Mo as strengthening alloy elements.Compared with AISI 4130, it has a higher carbon content with good balance of strength, toughness ,abrasion and impact resistance and heat treatment capabilities,but poor in weldability characteristics.AISI 4140 is generally supplied in quenched and tempered condition with hardness 28-32HRC
