S420NL carbon steel plate sheet Alloy Steel Plate

The boiler steel plate is used to manufacture various boilers and important accessories. Because the S420NL carbon steel plate sheet boiler steel plate works under the medium temperature (below 350 ° C) and high pressure state, it is not only subject to high pressure, but also to impact, fatigue load and water and air corrosion. The boiler steel plate is required to ensure certain strength and good welding and cold bending performance.Bridge steel plate S420NL carbon steel plate sheet is used for large railway bridge. The bridge steel plate is required to bear dynamic load, impact, vibration, corrosion resistance, etc.

37SiMn2MoV steel is high-grade quenched and tempered steel. S420NL carbon steel plate sheet, 37SiMn2MoV steel has excellent comprehensive mechanical properties, good heat treatment process, good hardenability, low sensitivity to quenching crack, high resistance to tempering, very low temper brittleness, good high temperature strength and low temperature toughness. Chemical composition of 37SiMn2MoV steel: C: 0.33-0.39, Si: 0.60-0.90, Mn: 1.60-1.90, Mo 0.40-0.50, V: 0.05-0.12. After quenching and tempering, 37SiMn2MoV steel is usually used to manufacture heavy load and large section important parts.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This S420NL carbon steel plate sheet rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.
