1.Introduce

Carbon steel is a common metal material, because of its excellent physical properties and a wide range of applications, has been widely concerned. This paper will introduce the relevant information of SAE1055 in detail, including its chemical composition, physical properties, heat treatment process and application fields.

2.chemical composition

The chemical composition of SAE1055 mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements. Its chemical composition is as follows:

Carbon (C) content: 0.50%-0.60%

Silicon (Si) content: 0.15%-0.35%

Manganese (Mn) content: 0.60%-0.90%

Phosphorus (P) content: ≤0.035%

Sulfur (S) content: ≤0.040%

3. Physical properties

1. Density: The density of SAE1055 is about 7.85 g/cm ³.

2. Elastic modulus: The elastic modulus of SAE1055 is 200-210 kg/m3, which has high elasticity.

3. Tensile strength: The tensile strength of SAE1055 is 440-570 mpa, which has high strength.

4. Yield strength: SAE1055 yield strength is 370 mpa.

5. Elongation: The elongation of SAE1055 is more than 20%, which has good ductility.

4. heat treatment process

SAE1055 has a certain tunability, and its physical properties can be changed by heat treatment process. Common heat treatment processes are quenching, tempering and normalizing.

1. Quenching: the SAE1055 is heated to a suitable temperature, and then quickly cooled to achieve a higher hardness and strength.

2. Tempering: After quenching, the SAE1055 is heated to the appropriate temperature, and then cooled after a period of time to reduce the brittleness brought by quenching and improve toughness.

3. Normalizing: Heat SAE1055 to a suitable temperature, keep it for a period of time and then cool it naturally to obtain medium hardness and strength.

5. Application fields

Due to its high strength and toughness, SAE1055 is widely used in machinery manufacturing, automobile manufacturing, construction engineering and aerospace and other fields. Specific applications include the manufacture of springs, chains, gears, bearings and tools.

Vi. Conclusion

SAE1055 is a common metal material with high strength and toughness, and its chemical composition, physical properties, heat treatment process and application fields are of great significance to the research and production of related industries. Through in-depth understanding of SAE1055 related information, it can be better applied in actual production, improve product quality and performance.
