Description

AISI 4140 Alloy Structural Steel 6.0mm-1200mm Hot Rolled Bright

AISI 4140 steel is Chrome-Moly High Tensile Steel which has at least 0.8%Cr,0.15%Mo as strengthening alloy elements.The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 steel can be oil hardened to a relatively high level of hardness with a tensile strength of 850 – 1000 MPa.AISI 4140 offers a very good balance of strength,toughness and wear-resistance.Compared with AISI 4130,it has a slightly higher carbon content which gives greater strength and heat treatment capabilities , however it is poor in weldability.Pre hardened and tempered 4140 can be further surface hardened by flame or induction hardening(can be surface hardened to a typical value 58HRC)and by nitriding( Surface hardness achievable is 600 to 650HV).
