steel grade q345r price is relatively stable

The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of steel grade q345r steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special steel grade q345r materials and specifications can be ordered in advance.

High strength wear-resistant plate is a kind of plate product used for large area wear condition. It is made by overlaying a certain thickness of high hardness and excellent wear-resistant layer on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity. After production, the high-strength wear-resistant plate will be tested for its strength and bearing pressure. High strength wear-resistant plate is very wear-resistant, in the case of no accident, the service life of steel grade q345r, high-strength wear-resistant plate is very long.

steel grade q345r, Chinese grade 45 steel belongs to high quality carbon structural steel. The application of steel grade q345r, Chinese grade 45 steel depends on its various properties. steel grade q345r, Chinese grade 45 steel has certain toughness and plasticity, high strength and good machinability. Good comprehensive mechanical properties of Chinese grade 45 steel can be obtained by quenching and tempering treatment. Chinese grade 45 steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.

Alloy steel plate: The primary purpose of adding alloy elements to steel is to improve the hardenability of the steel, and it is easy to obtain martensite during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are smaller, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, steel grade q345r.
