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 hot rolled steel A36, 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.
Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.
hot rolled steel A36 discount steel plate and sheet (size mm) supply: 10*2200*12000, 18*2000*000, 14*2000*12000, 22*2500*1000, 12*2000*11000, 16*2500*10000, 14*2000*11000, 25*2000*10000, 12*2000*12000, 14*2500*10000, 14*2000*10000, 20*2500*10000, 12*1800*10000, 16*2200*000, 14*2000*9000, 22*2200*1000, 12*1800*9000, 16*2000*10,000, 16*1800*10000, 14*1800*9000, 20*2000*10000, 22*2200*10000, 30*2500*10000.
At the same time of doing well in hot rolled steel A36 production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the hot rolled steel A36 technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
