Detailed explanation of S420M steel plate

The types of steel plate are very diverse. S420M steel plate is a common carbon and low alloy steel plate, which belongs to the steel plate grade under the European standard. Steel plate has played a huge role in the industrial process. S420M steel plate has good tensile strength and machinability, and can be used to manufacture some engineering equipment, mining equipment, etc.

Chemical composition of S420M steel plate (melting analysis):
C carbon: 0.16;
Si silicon: 0.50;
Mn manganese: 1.00 - 1.70;
P phosphorus: 0.025;
S sulfur: 0.02;
The chemical composition determines the properties of S420M steel plate, so the final chemical composition shall be subject to the material specification of S420M steel plate.

Mechanical properties of S420M steel plate:
The yield strength of S420M steel plate needs to be greater than or equal to 420 MPa;
The tensile strength of S420M steel plate should be 520 to 680 MPa or more;
The elongation after fracture of S420M steel plate shall be greater than or equal to 19%;

Delivery status of S420M steel plate (heat treatment):
The S420M steel plate can be delivered by normalizing or hot-rolling heat treatment process, depending on the scope of use and use requirements. If there is a requirement for the tensile yield strength of the steel plate, it can be delivered by normalizing heat treatment process.
