EN 10025 S420M steel plates suppliers

What is the specific use of EN 10025 S420M steel plates, hot rolled plate in daily life? First of all, hot rolled plate is used in bridge, vehicle structure, frame and other fields to play a role of bearing pressure. Secondly, high pressure boiler vessels are also made of hot rolled plates, which can be heat-resistant and airtight, and can stably seal the hot gas in the container. Thirdly, stainless steel hot rolled plate can be used to process hardware products. It has excellent corrosion resistance, and is easy for processing.

EN10025-3 S460N high-strength steel has high strength, especially in normalizing or normalizing and tempering state. It has higher comprehensive mechanical properties. S460N plates are mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. S460N mechanical properties: tensile strength Rm500-680MPa, yield strength: 420-320MPa, elongation after fracture 18-19%.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the EN 10025 S420M steel plates metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between EN 10025 S420M steel plates strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
