Carbon steel Carbon steel 1055 contains less than 1.35% carbon and contains no other alloying elements except iron, carbon and limited impurities such as silicon, manganese, phosphorus and sulfur. The properties of carbon steel mainly depend on the carbon content. As the carbon content increases, the strength and hardness of the steel increase, and the plasticity, toughness and weldability decrease. Compared with other steel types, carbon steel is used earliest, has low cost, wide performance range and the largest usage. Suitable for media such as water, steam, air, hydrogen, ammonia, nitrogen and petroleum products with nominal pressure PN≤32.0MPa and temperature of -30-425℃. According to the carbon content, it is divided into low carbon steel (carbon content 0.04% ~ 0.25%), medium carbon steel (carbon content 0.25% ~ 0.6%), and high carbon steel (carbon content 0.6% ~ 1.35%). According to quality, it is divided into ordinary carbon steel, whose harmful impurities phosphorus and sulfur content are less than 0.05%, including Class A steel (Class A steel, guaranteed mechanical properties), Class B steel (Class B steel, guaranteed chemical composition) and special class Steel (C-type steel, ensuring mechanical properties and chemical composition).
