What are the precautions during the processing of EN 10025 S420M steel

In recent years, in line with the development trend of iron and EN 10025 S420M steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which EN 10025 S420M steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

The boiler steel plate is used to manufacture various boilers and important accessories. Because the EN 10025 S420M steel 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 EN 10025 S420M steel is used for large railway bridge. The bridge steel plate is required to bear dynamic load, impact, vibration, corrosion resistance, etc.

Wear resistant steel is very wear-resistant: for example, excavator bucket, long-term excavation requires good wear resistance. Wear resistant steel has a very high hardness: for example, scraper conveyor, if the hardness is not up to standard, it is extremely easy to fracture, resulting in very serious consequences. Wear resistant steel has good corrosion resistance: many equipment need to transport chemical corrosion products, so corrosion-resistant mechanical equipment is needed. EN 10025 S420M steel, Wear resistant steel has good fatigue resistance: such as bearing steel ball, which can do fast and repeated movement, and need to guarantee performance.

The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, EN 10025 S420M steel. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.

EN 10025 S420M steel, P355GH steel yield strength in different thickness has different values.Thickness 8-16mm: 355MPa min., ＞16-40mm: 345MPa min., ＞40-60mm: 335MPa min., ＞60-100mm: 315MPa min., ＞100-150mm: 295MPa min., ＞150-250mm: 280MPa min. The elongation minimum is 20%. P355GH plate under EN10028-2:2003 standard is a pressure vessel steel. It is always delivered in hot rolling, controlled rolling, normalizing.
