16MnDR steel plate is suitable for low temperature pressure vessels manufacturing. Grade 16Mn- indicates that the content of manganese (Mn) in the steel plate is relatively high, about 1% -1.6%, D- indicates low temperature, R- indicates pressure vessel. (Normally, when the content of a certain chemical element in steel is high, it needs to be marked in the material, for example, 1.6% manganese is written as 16Mn; certain elements such as Cr and Mo are higher, written as Cr1, Mo1, Such as 12Cr2Mo1R.) The normal delivery status is normalized delivery (Normalized).
Manganese steel plate is a kind of common steel, which is a kind of high-strength anti manganese steel. ASTM A573 CS steel carbon plate, Manganese steel plate is mainly used to bear the impact, extrusion, material wear and other severe working conditions. It is a typical anti-wear steel, with austenite and carbide as cast structure. After water quenching at about 1000 ° C, the structure changes into single austenite or austenite with a small amount of carbide.
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 A573 CS steel carbon 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.
