ASTM A283 Grade C Carbon Steel Plate for Low-Stress Structural Fabrication

ASTM A283 Grade C is a carbon steel plate grade governed by ASTM A283 standard, formulated for general-purpose structures requiring moderate tensile strength. This grade targets non-critical load-bearing components and atmospheric storage equipment. Compared with higher-strength structural steel, A283 Grade C focuses on cost efficiency while maintaining reliable quality for light and medium-load projects.
This plate grade provides uniform mechanical performance with good plasticity and convenient welding characteristics. The low carbon content reduces cracking risks during welding and hot forming. Fabricators can easily conduct oxy-fuel cutting, bending and rolling operations. Controlled impurity levels ensure stable surface quality and reduce rejection rates during secondary processing.
ASTM A283 Grade C steel plate is commonly used for atmospheric storage tanks, silos, equipment supports, workshop auxiliary frames and light transport structures. It is highly popular in water tank fabrication and general machinery base manufacturing. Our inventory covers multiple thicknesses of A283 Grade C hot rolled plates, supporting bulk export and cut-to-size orders.
