What is carbon steel, carbon manganese steel?
Carbon steel: carbon content less than 1.35%, excluding iron, carbon and limited within the limits of silicon, manganese, phosphorus, sulfur and other impurities, excluding other alloy elements of steel. The performance of carbon steel depends mainly on carbon content. With the increase of carbon content, the strength and hardness of the steel increases, and the plasticity, toughness and weldability decrease.
Compared with other kinds of steel, carbon steel is the earliest, low cost, wide performance range and the largest amount. For nominal pressure PN is less than or equal to 32.0MPa, temperature of -30-425 water, steam, air, hydrogen, ammonia, nitrogen and petroleum products such as medium. Commonly used grades are WC1, WCB, ZG25 and high quality steel 20, 25, 30 and low-alloy structural steel 16Mn
Carbon manganese steel is a high-quality carbon structural steel in the higher manganese content of carbon steel, manganese elements are generally marked in the rear, such as 20Mn, 40Mn and so on
