Q345E steel is low-alloy high-strength steel with good low-temperature impact properties. The grade of Q345E steel is composed of three parts: Chinese phonetic alphabet representing yield strength, yield strength value and quality grade symbol. Where: Q is the yield strength; 345 is the yield strength value in MPa; E is the grade (passing the - 40 degree impact test). SA573 Grade 65 carbon steel, Q345E steel is mainly used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, power stations, workshops, low-temperature pressure vessels, etc.

SA573 Grade 65 carbon steel, Chinese grade 45 steel belongs to high quality carbon structural steel. The application of SA573 Grade 65 carbon steel, Chinese grade 45 steel depends on its various properties. SA573 Grade 65 carbon 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.

SA573 Grade 65 carbon steel, S355j2g3 steel plate is a kind of main atmospheric corrosion-resistant steel, s355j2g1w steel plate is a kind of weathering structural steel, its mechanical properties are similar to s355j2g2. By adding CR, Cu and Ni, the oxide layer is firmly attached to the workpiece surface. This oxide layer prevents further corrosion of the steel.

According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. SA573 Grade 65 carbon steel, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.
