The application and research history of steel is quite long, but until the invention of the Bayesian steel making method in the 19th century, the production of steel was a high-cost and low-efficiency work. Nowadays, steel has become the world with its low price and reliable performance. One of the most used materials on the Internet is an indispensable ingredient in the construction industry, manufacturing industry and people’s daily lives. It can be said that steel is the material basis of modern society. Steel is a very important metal material in all fields of economic construction.
When you choose a carbide insert to process your material, confirm the characteristics of the processed material is very important.
Low-carbon steel is carbon steel with a carbon content of less than 0.25%, which has low strength and hardness, and good plasticity and toughness, so it is also called mild steel. Low-carbon steel generally does not undergo heat treatment before use, and can be cold-formed by methods such as crimping, bending, and stamping. Low carbon steel is easy to accept various processing such as forging, welding and cutting.
2.Medium carbon steel
Medium carbon steel is a carbon steel with a carbon content of 0.25% to 0.60%. There are various products such as killed steel, semi-killed steel, and rimmed steel. Medium-carbon steel has higher strength and hardness than low-carbon steel, and lower plasticity and toughness than low-carbon steel.
Its thermal processing and cutting performance is good, and its welding performance is poor. Hot-rolled and cold-drawn materials can be used directly without heat treatment, or they can be used after heat treatment.
The quenched and tempered medium carbon steel has good comprehensive mechanical properties, the highest hardness that can be reached is about HRC55 (HB538), and the σb is 600-1 100 MPa. Therefore, medium carbon steel is the most widely used in various applications of medium strength level. In addition to being used as a building material, it is also widely used in the manufacture of various mechanical parts.
3.High carbon steel
High carbon steel, often called tool steel, has a carbon content of more than 0.60%, high hardness, but is brittle and easy to break, and can be hardened and tempered. In practical applications, hammers and crowbars are made of high-carbon steel with a carbon content of 0.75%; cutting tools such as drills, taps, and reamers are made of steel with a carbon content of 0.90% to 1.00%.
