Flat Stock, Steel, 4140, 1 1/2 x 4 In, 6 Ft
This 4140 alloy steel flat stock is a versatile and durable material ideal for a wide range of applications, including machinery parts, tooling, and structural components. Its high strength-to-weight ratio and excellent resistance to fatigue make it a popular choice for heavy-duty machinery and equipment. The steel can be heat-treated for increased hardness and machinability, making it suitable for use in aerospace, automotive, and industrial manufacturing. Its flat, rectangular shape is easy to work with, and its cold-rolled finish provides a smooth surface for machining. With a yield strength of 60,000 psi and tensile strength of 95,000 psi, this steel is a reliable choice for demanding applications.
