What does steel grade EN10025-4 S420M steel mean

The clad steel plate is a bimetallic plate that uses ordinary carbon structural steel, high-quality carbon structural steel and low alloy steel as the base (base layer).Then use stainless acid-resistant and heat-resistant steel as the surface layer (multilayer). It is mainly used to manufacture structural parts and containers that are resistant to acids, alkalis, atmosphere and corrosive media. The main grades of clad steel plate: 0Cr19Ni9, 1Cr19Ni9, 00Cr19Ni11, 0Cr17Ni12MO2, 0Cr18Ni11Nb (the above is austenitic), 1Cr13, 0Cr13, 2Cr13, EN10025-4 S420M steel, 3Cr13.

The basic principle of EN10025-4 S420M steel, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.

What are the characteristics of medium and thick plate, EN10025-4 S420M steel? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, EN10025-4 S420M steel is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.
