Explanation
It was once called carbon steel or carbon steel. Iron carbon alloy with carbon content less than 2.11% and no other alloy elements intentionally added (i.e. only containing carbon and common elements within the limit, such as silicon, manganese, sulfur, phosphorus, copper, oxygen, nitrogen, etc.). According to the carbon content, it can be divided into low-cardon steel, medium carbon steel and high carbon steel; According to the type of equilibrium structure, it can be divided into hypo-eutectoid steel, eutectoid steel and over eutectoid steel; According to metallurgical quality, it can be divided into plain steel, high-quality steel, high-grade high-quality steel and super-quality steel; According to the hardness used, it can be divided into mild steel, semi mild steel, semi hard steel, hard steel and extra hard steel.
