What is 27SiMn steel material

27SiMn steel material chemical element: C: 0.24-0.32, Si: 1.10-1.40, Mn: 1.10-1.40.

27SiMn steel material mechanical properties: tensile strength 980 MPa; yield strength: 835 MPa; elongation after fracture: 12; reduction of area: 40; impact energy: 39J.

For 27SiMn steel material, 27 represents the carbon content in this material, and the following Si and Mn represent the restrictions on the content of Si and Mn in this material. This 27SiMn steel material has high strength and wear resistance, high hardenability, medium plasticity during cold deformation, good machinability and fair weldability. In heat treatment, the toughness of 27SiMn steel material is less, and it can still maintain high toughness when water cooling, but it has the tendency of overheat sensitivity, white spot sensitivity and temper brittleness. Most of them are used after preparation, and can also be used in normalizing or hot rolling supply.

27SiMn steel material can be used to make hot stamping parts with high toughness and wear resistance, and parts used without heat treatment or normalizing, such as tractor track pin.
