nm300 steel equivalent grades main useage

35SiMn steel can be used to manufacture parts with medium speed and medium load under the condition of quenching and tempering. 35SiMn steel can also be used to manufacture parts with high load, small impact and vibration, and parts with large cross-section and surface hardening, such as the main shaft and hub of steam turbine, impeller and various important fasteners, transmission shaft, main shaft, mandrel, connecting rod, gear, worm and trolley shaft in general machinery. In addition, nm300 steel equivalent grades, 35SiMn steel can also be used to make thin-walled seamless steel pipe.The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, nm300 steel equivalent grades steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and nm300 steel equivalent grades carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.Quenching Improve the hardness of nm300 steel equivalent grades steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of nm300 steel equivalent grades steel and comprehensive mechanical properties.The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, nm300 steel equivalent grades. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.It is very important for a company to have a sound after-sales service system, which better guarantees the interests of customers and increases the reliability of the company's products in the hearts of customers.
