Application | The carbon content of carbon tool steel is between 0.65 and 1.35%. After heat treatment, high hardness and high wear resistance can be obtained. It is mainly used to make various tools, cutting tools, molds and measuring tools, and plain carbon round steel, that is carbon-containing The general purpose of low-carbon steel with a content of less than 28% is: structures with low tensile strength requirements, such as ordinary construction steel, ordinary standard parts, hot-rolled steel, etc. Carbon-bonded round steel, the full name is high-quality carbon structural steel, which contains low content of harmful elements sulfur and phosphorus (≤0.035%). Among them, the grades of 08, 10, 15, 20, 25 are low-carbon steels, and their plasticity is good. , Easy to draw, extrude, stamp, forge and weld, of which 20 steel is the most widely used. No. 30-55 belongs to medium carbon steel. After quenching and tempering, excellent mechanical properties can be obtained, and it is often used as more important shafts, fasteners, etc. No. 60 and above belong to high-carbon steel, making springs and wear-resistant parts. 20CrMnTi is an important carburizing steel, suitable for important gears. 27SiMn is a high-strength, easy-to-weld steel, used in important places where welding is required. 35CrMo and 42CrMo are high-strength steels used for very important parts, such as connecting rod screws and cylinder head screws for engines. Tire screws for heavy-duty cars, etc. |
