Hot rolled hardess of nm500 steel plate yield strength value

S355NL normalized steel has different impact energy requirement for impact tests at different temperature environment. S355NL plate shall be done impacting test in longitudinal direction under -50℃ with the minimum energy 27J. When customers request done charpy_V notch test under -20℃,then the impacting energy shall be above 47J. For the transverse direction,the engery shall be above 16J under the temperature -50℃. The hardess of NM500 steel plate, steel Grade S355NL making process shall according to EN10025-1,hardess of NM500 steel plate.The company now has oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments The staff with college degree or above accounted for more than 80%, and there were more than 30 professional and technical personnel The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m,hardess of NM500 steel plate.The main applications of normalizing are as follows:① For low carbon steel, hardess of NM500 steel plate. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the alloy wear-resistant steel plate is significantly improved.Hardess of NM500 steel plate,Since its establishment, the company has been deeply supported and loved by customers with its unique business philosophy and business model.
