What is EN S420M steel plate equivalent Indian material

The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with EN S420M steel plate, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched EN S420M steel plate increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of EN S420M steel plate during tempering, while tempering determines the performance and life of the workpiece.
