Detailed Images
Round steel refers to long solid steel with circular section. Its specifications are expressed in diameter, in millimeters (mm). For example, "50mm" means round steel with a diameter of 50mm
Classification by chemical composition
Carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel according to chemical composition (i.e. carbon content).
(1) Low carbon steel
Also known as mild steel, low carbon steel with carbon content from 0.10% to 0.30% is easy to accept various processing, such as forging, welding and cutting. It is commonly used in the manufacture of chains, rivets, bolts, shafts, etc.
(2) Medium carbon steel
Carbon steel with carbon content of 0.25% ~ 0.60%. There are killed steel, semi killed steel, boiling steel and other products. In addition to carbon, it can also contain a small amount of manganese (0.70% ~ 1.20%). According to the product quality, it is divided into ordinary carbon structural steel and high-quality carbon structural steel. Good hot working and cutting performance, poor welding performance. The strength and hardness are higher than those of low carbon steel, while the plasticity and toughness are lower than those of low carbon steel. Hot rolled and cold drawn materials can be directly used without heat treatment, and can also be used after heat treatment. The quenched and tempered medium carbon steel has good comprehensive mechanical properties. The maximum hardness that can be achieved is about HRC55 (hb538), σ B is 600 ~ 1100mpa. Therefore, medium carbon steel is the most widely used in various applications with medium strength level. In addition to being used as building materials, it is also widely used to manufacture various mechanical parts.
(3) High carbon steel
It is often called tool steel, with carbon content ranging from 0.60% to 1.70%, which can be hardened and tempered. Hammer and crowbar are made of steel with carbon content of 0.75%; cutting tools such as drill bit, tap and reamer are made of steel with carbon content of 0.90% to 1.00%.
Classification by steel quality
According to the quality of steel, it can be divided into ordinary carbon steel and high-quality carbon steel.
(1) Ordinary carbon structural steel, also known as ordinary carbon steel, has wide restrictions on carbon content, performance range and content of phosphorus, sulfur and other residual elements. In China and some countries, it is divided into three categories according to the guarantee conditions of delivery: class a steel (class a steel) is the steel to ensure mechanical properties. Class B steel (class B steel) is the steel to ensure chemical composition. Special steel (Class C steel) is a steel that ensures both mechanical properties and chemical composition. It is often used to manufacture important structural parts. A3 steel (class a No. 3 steel) with carbon content of about 0.20% is produced and used most in China, which is mainly used for engineering structures.
Some carbon structural steels also add trace amounts of aluminum or niobium (or other carbide forming elements) Nitride or carbide particles are formed to limit grain growth, strengthen steel and save steel. In China and some countries, in order to meet the special requirements of professional steel, the chemical composition and properties of ordinary carbon structural steel are adjusted, so as to develop a series of professional steel of ordinary carbon structural steel (such as steel for bridge, construction, reinforcement, pressure vessel, etc.).
(2) Compared with ordinary carbon structural steel, high-quality carbon structural steel has lower contents of sulfur, phosphorus and other non-metallic inclusions. According to different carbon content and uses, this kind of steel is roughly divided into three categories:
① Less than 0.25% C is low carbon steel, especially 08F and 08Al with carbon content less than 0.10%. Due to their good deep drawing and weldability, they are widely used as deep drawing parts, such as automobiles and can making... Etc. 20g is the main material for manufacturing Ordinary boilers. In addition, low carbon steel is also widely used as carburized steel for machinery manufacturing.
② 0.25 ~ 0.60% C is medium carbon steel, which is mostly used in quenched and tempered state to make parts for machinery manufacturing industry.
③ More than 0.6% C is high carbon steel, which is mostly used to manufacture springs, gears, rolls, etc.
According to the different manganese content, it can be divided into two groups: ordinary manganese content (0.25 ~ 0.8%) and high manganese content (0.7 ~ 1.0% and 0.9 ~ 1.2%). Manganese can improve the hardenability of steel, strengthen ferrite and improve the yield strength, tensile strength and wear resistance of steel. Usually, the brand of steel with high manganese content is marked with "Mn", such as 15mn and 20Mn, to distinguish it from carbon steel with normal manganese content.
Classification by use
According to the purpose, it can be divided into carbon structural steel and carbon tool steel.
The carbon content of carbon tool steel is between 0.65 ~ 1.35%. After heat treatment, it can obtain high hardness and high wear resistance. It is mainly used to manufacture various tools, cutting tools, molds and measuring tools (see tool steel).
Carbon structural steel is divided into 5 grades according to the yield strength of steel:
Q195,Q215,Q235,Q255,Q275
Due to different quality, each brand is divided into grades A, B, C and d. There are four at most, and some are only one; in addition, there are differences in deoxidation methods for steel smelting.
