AISI/SAE 4140 Carbon Steel Bar

AISI/SAE 4140 is a chromium-molybdenum alloy steel that boasts a unique combination of properties, making it ideal for applications that require both durability and reliability. With a carbon content of approximately 0.40%, this steel exhibits excellent hardenability, allowing it to achieve high hardness levels through heat treatment. The addition of chromium and molybdenum enhances its strength and resistance to deformation, ensuring that it can withstand the rigors of demanding environments.

The round shape of AISI/SAE 4140 steel makes it particularly versatile, allowing for easy machining and fabrication into various components. Whether you need shafts, gears, or structural parts, this steel can be easily processed to meet your specific requirements. Its excellent weldability further expands its usability, making it suitable for a variety of manufacturing techniques.
