SAE 1055 SAE J 403

SAE 1055 SAE J 403

SAE 1055 is a high-quality carbon steel that is widely used in the manufacture of machine parts, automotive parts, tools and forgings. The physical properties and chemical properties of the material are very excellent, so it is favored by the industry.

In the process of using SAE 1055, attention should be paid to protecting its surface from corrosion, oxidation and other factors, so as not to affect its performance. At the same time, when processing the material, it is also necessary to pay attention to the accuracy and safety of processing technology to ensure the quality of products and the safety of workers.

As one of the important materials in modern industry, SAE 1055 has a very broad application prospect. With the continuous development of industrialization, people's demand for high-quality materials will be increasing. Therefore, the market potential of SAE 1055 is very huge, which deserves our attention and play in the use and promotio

SAE 1055:

1. Chemical composition requirements: carbon (C) content in 0.52%-0.60%, manganese (Mn) content in 0.60%-0.90%.

2. Mechanical properties: tensile strength between 620 MPa and 1030 MPa, yield strength between 350 MPa and 930 MPa, elongation between 10% and 25%.

3. Heat treatment: Steel can be normalized or annealed, and has good processing properties.
