45 # steel

45 Steel is a high -quality carbon structure steel, which has good hardness and strength, and is suitable for making high -strength, high wear -resistant, high -precision mechanical parts and molds. In addition, the steel species also has the characteristics of weldability, thermal processability and cold deformation processing performance. However, 45 steel is relatively weak in terms of corrosion resistance and plasticity, and it is necessary to pay attention to the temperature of anti -rust and processing.

Q235 steel

Q235 steel is a commonly used carbon structure steel. Its material is relatively soft and suitable for manufacturing pressure vessels, bridges, buildings, mechanical parts, etc. The steel species has the characteristics of good welding performance, good plasticity, good toughness, and good hot and cold processing performance. However, it is easy to crack in harsh environments such as high temperature and high pressure, and preventive measures need to be paid to strengthening prevention measures.

20#Steel

20#Steel is a common carbon structure steel. It has the characteristics of moderate hardness, good weldability, and processable molding. It is widely used in manufacturing machine components, bearings, and automotive parts. It is worth noting that 20#Steel is prone to plastic breaks under high temperature and high pressure, and it is necessary to pay attention to strengthening safety protection.

65mn steel

65mn steel has good hardness and abrasion resistance, and is commonly used tool steel and spring steel. In addition, 65MN steel also has the characteristics of good plasticity and excellent thermal processing performance. It should be noted that it is prone to oxidation at high temperature, which seriously affects its service life.

C45 steel

C45 steel is a commonly used medium -carbon steel, which has good hardness and strength. It is suitable for manufacturing and low load mechanical parts and bearings. In addition, the steel type is prone to cracks during thermal processing, and it is necessary to pay attention to strengthening thermal treatment and cooling measures.

In short, there are many types of carbon steel materials. To choose a suitable carbon steel material that is suitable for you, you need to take into account multiple factors such as specific use scenarios, working conditions, and performance requirements.
