15Mo3 heat resistant steel plate for boiler and pressure vessel executive standard: DIN1715515Mo3 heat resistant steel plate delivery status: normally delivered in normalized status. According to the special agreement at the time of ordering, 15Mo3 heat resistant steel plate also be delivered in non processed status.15Mo3 heat resistant steel plate is mainly used for steam boiler equipment, 25CrMo4 nickel alloy steel material for fastener, pressure vessels, large pressure pipes, drum manufacturing of utility boilers and similar components.
40Cr steel belongs to alloy structural steel. 25CrMo4 nickel alloy steel material for fastener, 40Cr steel has good comprehensive properties, low temperature impact toughness and low notch sensitivity after quenching and tempering on the basis of high-quality carbon structural steel No. 40. 40Cr steel mechanical properties: tensile strength: ≥ 980mpa, yield strength: ≥ 785MPa, elongation after fracture: ≥ 9%, elongation after fracture: ≥ 45%, impact absorption energy: ≥ 47J. 40Cr steel chemical composition: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.80-1.10.
The basic phases of 25CrMo4 nickel alloy steel material for fastener, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.
Pressure vessel steel plates are mainly used for manufacturing pressure vessels and other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of pressure vessel steel plates ranges from normal pressure to 320kg / cm2 or even 630kg / cm2, and the temperature ranges from - 20 °C to 450 °C. In addition to certain strength, good plasticity and toughness, pressure vessel steel plates must also have good cold bending and welding properties. Q245R, Q345R, 14Cr1MoR, 15CrMoR, 25CrMo4 nickel alloy steel material for fastener etc. are common pressure vessel steel grades.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled 25CrMo4 nickel alloy steel material for fastener plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive 25CrMo4 nickel alloy steel material for fastener industry and agriculture equipment.
