Alloy Steel Rectangle Bar 4140 Heat Treat

-69 Products

4140 is a chromium-molybdenum alloy steel renowned for its high strength, toughness, and wear resistance after heat treatment. The rectangular bar shape of this low-alloy steel makes it ideal for machining components with flat surfaces and perpendicular edges, such as gears, shafts, and fixtures across industries like aerospace, automotive, and oil & gas. Its superior mechanical properties, including high tensile strength, fatigue strength, and impact resistance, make it a popular choice for critical applications requiring durability and reliability.
