A366/1008 Steel Supply

A366/1008 Carbon Steel is generally used for "commercial quality" cold rolled steel sheet. It is known for its very good formability and comparatively high strength. It has a very good surface finish that is far superior to hot rolled A36.

 A366/1008 Carbon Steel Properties

Strength: A366/1008 carbon steel has low strength, making it ideal for applications that require low mechanical strength. It has a minimum tensile strength of 420 MPa and a minimum yield strength of 320 MPa.

Ductility: A366/1008 carbon steel has excellent 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: A366/1008 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: A366/1008 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: A366/1008 carbon steel is magnetic, which makes it suitable for applications that require magnetic properties.

Corrosion Resistance: A366/1008 carbon steel is not known for its corrosion resistance and may require additional treatments or coatings to prevent corrosion.
