S420M and S420ML are hot-rolled flat weldable fine-grained structural steel with a thickness less than 120mm. S420M material properties, S420 steel is a non-alloy structural steel. The S420ML steel is composed of the following parts: S (structural steel); 420: the yield strength value of structural steel with a thickness less than 16mm: not less than 420; M represents his delivery status, that is, hot mechanical rolling; L: The impact when the temperature is not lower than -50 degrees is marked with a capital letter L.

The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as S420M material properties, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.

Its weatherability is the protection of the oxide layer of weatherproof steel. The mechanism of corrosion resistance of weathering steel is mainly based on the analysis of long-term exposed rust layer. Generally speaking, it is believed that weathering steel can form a dense layer of weathering rust through long-term exposure, which has a good protective effect on weathering steel, S420M material properties.

The carbon content of S420M material properties, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
