The CCS AH40 high tensile steel plate plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The CCS AH40 high tensile steel plate products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.
Steel S275J0 is a carbon structural steel grade. Our mill can produce S275J0 carbon steel plates up to 400mm thickness. Generally speaking, as rolled condition for S275J0 carbon steel plate is Ok. Our mill would like to provide customers' normalized delivery condition if they indicate in their purchase order. CCS AH40 high tensile steel plate, Structural steel S275J0 has a specified minimum yield strength at ambient temperature of 275MPa when plates thickness less than 16mm.
The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length CCS AH40 high tensile steel plate is suitable for the length required by the construction of steel pipes.
Hot rolled CCS AH40 high tensile steel plate steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the CCS AH40 high tensile steel plate processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.
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, CCS AH40 high tensile steel plate. 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.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel CCS AH40 high tensile steel plate plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
