Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with SA572 Grade 415 steel hardness, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.
Increasing the use of high-end steel will help reduce carbon emissions. The use of high-strength, high-toughness, corrosion-resistant and wear-resistant, fatigue-resistant, and long-life steel materials should be increased; on the basis of meeting the requirements for the use of steel products, the integrated application of structural lightweight design, lightweight materials, and lightweight manufacturing technologies should be realized; Improve the yield rate of steel and optimize the steel recycling system.
There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products SA572 Grade 415 steel hardness are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.
