The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy ASTM A283 mild steel coil products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of ASTM A283 mild steel coil stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.
Q345DR steel is a pressure vessel special plate with yield strength of 340MPa grade. It has good comprehensive mechanical properties and process performance. Phosphorus, sulfur content than ordinary 16Mn steel, in addition to tensile strength, elongation requirements than ordinary 16Mn steel has been improved, but also required to ensure impact toughness. ASTM A283 mild steel coil was China's most widely used, the largest amount of pressure vessel special steel.
20G steel is boiler steel, which is similar to No. 20 carbon steel. The difference is that 20G steel has higher and stricter inspection standards than ASTM A283 mild steel coil, No. 20 carbon steel for harmful impurities and internal defects. That is to say, 20G steel is specially produced for boiler pressure vessels. It is special purpose "No. 20 carbon steel". The use of 20G steel to make boilers is not because it is more resistant to burning than other steels such as ASTM A283 mild steel coil, but because of its strength, toughness, ductility, weldability, temperature influence, fatigue fracture, price and cost, etc. 20G steel is most suitable for use in medium and low pressure boilers.
Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as ASTM A283 mild steel coil. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.
20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, ASTM A283 mild steel coil. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.
our company is a professional ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel exporter and a steel Stockist in china. We keep more than ASTM A283 mild steel coil 1000 tons ASTM A573 grade 70/A573 Gr.70 carbon manganese silicon steel plates steel in stock every month.
