Sa573 gr 58 high strength steel plate stockist

sa573 gr 58 high strength steel plate, Q345 angle steel has two kinds: unequal angle steel (two sides are not the same size) and equal angle steel (two sides are the same size). sa573 gr 58 high strength steel plate, Q345 angle steel is widely used for mechanical processing, building structure, steel structure, etc.. In addition, Q345 angle steel can withstand - 40℃ low temperature at least and can be used in cold areas. The weight calculation formula of Q345 angle steel: 0.00785 * (side width + side width - side thickness) * side thickness, the value obtained is the weight per meter, and then multiplied by the length to calculate the weight of a piece.

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, sa573 gr 58 high strength 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.
