Key Characteristics of A283 Grade C Carbon Steel

A283 Grade C is a low-to-intermediate tensile strength carbon steel plate that offers excellent welding characteristics and moderate strength. The chemical composition of A283 Grade C typically includes carbon (max 0.24%), manganese (0.90% max), phosphorus (0.035% max), and sulfur (0.040% max).

Mechanical Properties:

Yield Strength: ≥ 205 MPa

Tensile Strength: 380–515 MPa

Elongation: ≥ 20% (depending on thickness)

Due to its composition and properties, A283 Grade C is ideal for moderate load-bearing applications where durability and toughness are important but extreme strength is not required. It is often used in structural parts and light-duty pressure vessels.

Moreover, its good machinability and weldability make it easy to process using standard methods such as cutting, welding, and forming.
