ASTM A573 Grade 70(A573 Gr 70) steel, Chinese grade 45 steel belongs to high quality carbon structural steel. The application of ASTM A573 Grade 70(A573 Gr 70) steel, Chinese grade 45 steel depends on its various properties. ASTM A573 Grade 70(A573 Gr 70) steel, 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.
We have a large number of ASTM A573 Grade 70(A573 Gr 70) steel steel materials in stock, and provide deep processing services such as welding. In addition to simple welding parts, we can also weld H-beam, box column and other profiles. For such welded structure, our advantage is that there are high-quality and low-cost raw material steel plates, which can be cut into the ASTM A573 Grade 70(A573 Gr 70) steel required size and welded into steel products with required shape and size, without being limited by the specifications of rolling production lines.
