The UNS (Unified Numbering System) provides a standardized way to identify metals and alloys, while the SAE (Society of Automotive Engineers) designation is widely used in the automotive and engineering industries. Therefore, in terms of chemical composition, properties, and applications, SAE 1035 and UNS G10350 are identical.
SAE 1035 steel is a medium-carbon alloy valued for its balanced mechanical properties, including strength, ductility, and hardness. Understanding these properties is crucial for selecting the right material for specific applications.
The ultimate tensile strength of SAE 1035 steel ranges from 570 to 660 MPa (83,000 to 95,700 psi). This indicates the maximum stress the material can withstand while being stretched or pulled before breaking. Its high tensile strength makes SAE 1035 suitable for components that need to bear significant loads without failing.
Yield strength varies between 300 to 530 MPa (44,000 to 76,000 psi). Yield strength is critical as it indicates the stress at which the material begins to deform plastically. For example, in a car axle, this property ensures that the axle can handle everyday stresses without permanently bending.
Elongation at break, which measures the ductility of the material, typically ranges from 13% to 23%. This reflects its ability to undergo plastic deformation. The reduction in area, generally between 35% and 45%, also measures the material’s deformation capacity. Together, these properties indicate how much the material can be stretched or deformed before breaking, which is crucial for applications requiring flexibility and energy absorption during deformation.
The Brinell hardness of SAE 1035 steel typically falls between 160 to 210 HB, depending on the processing conditions. Hardness measures the material’s resistance to deformation, indentation, or scratching. Higher hardness values indicate better wear resistance, essential for components exposed to abrasive conditions.
The elastic modulus (Young’s modulus) of SAE 1035 steel ranges from 190 to 210 GPa (27 to 30 million psi). This property measures the material’s stiffness or rigidity, indicating its ability to deform elastically under stress. A higher modulus means the material is less likely to deform under elastic loads.
Fatigue strength ranges from 210 to 340 MPa (31,000 to 49,000 psi). This is crucial for applications involving cyclic loading, where the material is subjected to repeated stress cycles. High fatigue strength ensures the material can withstand many cycles of loading and unloading without failure.
