A513 (alloy 1020-1026) Steel Supply

A513(alloy 1020-1026) Carbon Steel is generally used for DOM tubing. Its higher carbon content means higher strength, but lower weldability and machinability.

A513 Carbon Steel Properties

Strength: A513 carbon steel has moderate strength, making it suitable for applications that require moderate mechanical strength. It has a minimum tensile strength of 520 MPa and a minimum yield strength of 400 MPa.

Ductility: A513 carbon steel has good ductility, which means that it can be easily formed and shaped without cracking or breaking. This property makes it ideal for applications that require complex shapes or designs.

Weldability: A513 carbon steel is known for its excellent weldability, making it a popular choice for welding, brazing, and soldering. It can be welded using common welding techniques, such as TIG, MIG, and stick welding.

Machinability: A513 carbon steel has good machinability, which means that it can be easily machined using common machining techniques, such as turning, milling, and drilling.

Magnetic Properties: A513 carbon steel is magnetic, which makes it suitable for applications that require magnetic properties.

Corrosion Resistance: A513 carbon steel is not known for its corrosion resistance and may require additional treatments or coatings to prevent corrosion.
