The tensile strength of typical flat steel varies depending on the grade of steel used. Generally, low-carbon flat steel, which is commonly used in general applications, has a tensile strength ranging from 370 MPa to 500 MPa. This level of tensile strength is sufficient for many non-structural applications, such as making parts for appliances, automotive components, and simple brackets. Medium-carbon flat steel has a higher tensile strength, usually between 500 MPa and 700 MPa. It is used in applications where greater strength is needed, such as in the construction of machinery parts that are subject to moderate loads. High-carbon flat steel, which is stronger but more brittle, can have a tensile strength exceeding 700 MPa. This type of flat steel is used in applications where high strength and wear resistance are required, such as in the manufacturing of tools, springs, and high-strength structural components. Alloy flat steel, which contains additional elements like manganese, chromium, or nickel, can have even higher tensile strengths, often exceeding 1000 MPa. These alloy flat steels are used in specialized applications, such as in the aerospace industry or in high-performance machinery, where extreme strength and durability are necessary. The tensile strength is a critical property as it determines the maximum amount of pulling force the flat steel can withstand before breaking, ensuring it can perform its intended function under stress.
