S420NL carbon steel plate sheet,15CrMo alloy plate is a heat-resistant steel with pearlite structure, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of S420NL carbon steel plate sheet and 15CrMo alloy plate is obvious and the weldability is poor. After welding, local high temperature tempering treatment should be carried out. The heat treatment process of 15CrMo alloy plate is as follows: the temperature rise rate is 200°C/h, the temperature is raised to 715°C for 1 hour and 15 minutes, the temperature drop rate is 100°C/h, and the temperature is reduced to 300°C before air cooling.

ASTM A285 grade A standard specification for pressure vessel plates. carbon steel, low- and intermediate-tensile strength.ASTM A285 grade A plates are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both.Supplementary Technology: HIC Test I NACE MR0175 1 215 | Z25 | 235 | S57 | S57.1| S58 | S58.1 1S3 |S4 Thickness: 6MM to 300MM.Width: 1500mm to 4050mm.

Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate has good processing performance Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low,S420NL carbon steel plate sheet.
