Product Introduction
SAE1055 steel is a high-quality carbon steel that is commonly used in various industrial applications. This steel is known for its excellent mechanical properties that make it a strong and durable material. Here are some of the mechanical properties of SAE1055 steel:
- Tensile strength: The tensile strength is around 630 MPa.
- Yield strength: The yield strength is around 530 MPa.
- Elongation: The elongation is about 10% to 15%.
- Hardness: The hardness of SAE1055 steel can vary based on the heat treatment process used, but typically ranges from 170 to 230 HB.
- Fatigue strength: The fatigue strength of SAE1055 steel is moderate and varies depending on the surface condition and the number of cycles.
- Impact strength: The impact strength of SAE1055 steel is relatively low compared to other grades of steel, making it less suitable for applications that require high impact resistance.
- Ductility: The ductility is moderate, allowing it to be easily formed and shaped into various industrial components.
