Alloy Steel NM400 steel for vehicle Plate Thickness

10CrMo9-10 steel plate is a kind of European standard pressure vessel steel plate, which is heat-resistant and high-pressure resistant boiler steel plate, belonging to alloy pressure vessel steel plate; 10CrMo9-10 steel plate is mainly used for power station boiler drum and steam boiler equipment. The NM400 steel for vehicle delivery state of 10CrMo9-10 steel plate is usually normalizing + tempering.

Special boiler steel is derived from carbon structural steel, NM400 steel for vehicle. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.

NM400 steel for vehicle annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of NM400 steel for vehicle annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. NM400 steel for vehicle annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality NM400 steel for vehicle products and excellent services. Our company's products NM400 steel for vehicle are widely used in petroleum, chemical, power station, boiler and other industries, mainly used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells and other equipment.
