What are the differences between low carbon steel, medium carbon steel and high carbon steel?
Recently, Jinan Suorong Steel Group has received orders inquiries for carbon steel from customers all over the world. Today, we would like to briefly introduce the classification of carbon steel for you:
Carbon steel according to the carbon content can be divided into:
① Mild steel, carbon content is less than 0.25%;
② Medium carbon steel, carbon content is 0.25%~0.6%;
③ High carbon steel, carbon content is greater than 0.6%.
mild steel (mild steel) because of its low strength, low hardness and soft, so it is also called mild steel. It includes most ordinary carbon structural steel and a part of high-quality carbon structural steel, most of which are used for engineering structural parts without heat treatment, some of which are used for mechanical parts requiring wear resistance after carburizing and other heat treatment.
Medium carbon steel has good hot working and cutting performance, but poor welding performance. The strength and hardness are higher than low carbon steel, but the plasticity and toughness are lower than low carbon steel. Cold rolled and cold drawn materials can be used directly without heat treatment or after heat treatment. The medium carbon steel after quenching and tempering has good comprehensive mechanical properties. The highest hardness achieved is about HRC55 (HB538), σb is 600 ~ 1100MPa. So in the medium strength level of various uses, medium carbon steel is the most widely used, in addition to as a building material, but also a large number of used in the manufacture of various mechanical parts.
High Carbon Steel, often called tool steel, has carbon content ranging from 0.60% to 1.70%, can be quenched and tempered, and has poor welding performance. Hammers and crowbars are made of steel with carbon content of 0.75%; Cutting tools such as drills, taps and reamers are manufactured from steel with carbon content ranging from 0.90% to 1.00%.
