What is the advantage of S420M steel plate

S420M steel plate is a low alloy high strength steel plate under European standard.

Chemical composition and melting analysis of S420M steel plate:
S420M steel plate → carbon element → ≤ 0.16;
S420M steel plate → silicon element → ≤ 0.50;
S420M steel plate → manganese element → ≤ 1.70;
S420M steel plate → phosphorus element → ≤ 0.030;
S420M steel plate → sulfur element → ≤ 0.025

Analysis of mechanical properties of S420M steel plate:
S420M steel plate → yield strength → ≥ 420 MPa;
S420M steel plate → tensile strength → ≥ 520 to 680 MPa;
S420M steel plate → elongation after fracture → ≥ 19%;
The yield strength of S420M steel plate is ≥ 420MPa. If it is listed according to the national standard, it is appropriate to use the national standard Q420 steel plate.

What is the density of S420M steel plate?
The density of S420M steel plate is generally 7.85 grams per cubic centimeter. It can be divided into four millimeters to sixty millimeters and sixty millimeters to 150 millimeters according to the thickness. The steel plate between sixty and 150 millimeters is attributed to S420M steel plate extra thick plate, the steel plate between four and sixty millimeters is attributed to S420M steel plate thick plate, and the steel plate between four millimeters and less than four millimeters is attributed to S420M steel plate thin plate.

Appearance requirements of S420M steel plate?
Whether the longitudinal orientation of the S420M steel plate is wrinkled? Assuming that the longitudinal orientation of the S420M steel plate is wrinkled, this belongs to the inferior S420M steel plate. Once the inferior S420M steel plate is wrinkled, it will crack immediately, resulting in the strength of the S420M steel plate. If it is used on buildings, it is likely to endanger people's lives. The pitted surface of S420M steel plate is caused by severe wear during binding. The high-quality S420M steel plate is very wear-resistant. Even if there is wear during binding, it will not show pitted surface.
