Carbon manganese steel


Carbon manganese steel: carbon content less than 1.35%, in addition to iron, carbon and limited within the silicon, manganese, phosphorus, sulfur and other impurities, excluding other alloying elements of steel. The performance of carbon steel is mainly dependent on the carbon content. Carbon content increases, the strength of the steel, the hardness increases, and reduces ductility, toughness and weldability. Compared to other types of steel, carbon steel using the earliest, low cost, wide range of performance, the largest amount. Suitable for nominal pressure PN ≤ 32.0MPa, temperature -30-425 ℃ water, steam, air, hydrogen, ammonia, nitrogen and petroleum products, and other media. Popular brands WC1, WCB, the ZG25 and quality steel 20, 25, 30, and low-alloy structural steel 16Mn
Carbon manganese steel is higher manganese content quality carbon structural steel, carbon steel, manganese generally just number back marked, 20Mn, 40Mn
