, SS400 steel is one of the most commonly used hot rolled general structural steel SS400 steel’s mechanical properties is yield strength more than 225-235MPa, tensile strength 360-510Mpa and 340-470Mpa For SS400 steel, the C element content is 02% max, the Mn element content is 140% max, the P element content is 0045% max, the S element content is 0045% max,a516 grade 70 hardness.

The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. a516 grade 70 hardness, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.
