ASTM A283 Grade C Plates are one of the most widely used carbon steel specifications for structural applications requiring low to intermediate tensile strength. As a hot-rolled steel, Grade C offers a highly desirable balance of strength, ductility, and cost-efficiency, making it the primary choice for projects where the extreme hardness of high-carbon alloys is not required. The material is characterized by its excellent formability and machinability, allowing it to be easily cut, bent, and shaped into various structural components without the risk of brittle failure.

The technical utility of ASTM A283 Gr.C is particularly evident in the construction of storage tanks, low-pressure vessels, and structural frames for buildings and bridges. Because of its low carbon content, this grade demonstrates exceptional weldability, enabling reliable joining through all standard industrial welding techniques. It is frequently utilized in the petroleum, water, and gas industries for the fabrication of large-diameter storage containers and non-critical structural supports. For engineers looking for a dependable, economical, and easy-to-fabricate material for general construction and atmospheric pressure applications, A283 Grade C plates provide a robust and versatile solution.



A283 GR.C Plates Features

  • » Balanced Tensile Strength: Offers a dependable tensile strength range of 55,000–75,000 psi, providing the ideal mechanical profile for structural and non-critical pressure applications.
  • » Excellent Weldability: Low carbon chemistry allows for seamless integration into welded structures using all conventional methods (SMAW, MIG, TIG) without requiring complex pre-heating.
  • » High Ductility and Formability: Grade C is specifically known for its superior cold-forming capabilities, allowing the plate to be bent or rolled into tank cylinders with ease.
  • » Superior Machinability: Exceptionally easy to cut, drill, and mill, which significantly reduces fabrication time and tooling costs during the manufacturing of base plates and gussets.
  • » Cost-Efficient Engineering: Provides one of the most economical solutions for large-scale construction projects, storage tank farms, and low-pressure piping systems.
  • » Predictable Mechanical Behavior: The hot-rolled manufacturing process ensures a uniform grain structure, resulting in consistent performance across varying plate thicknesses.
  • » Versatile Joining Options: In addition to welding, the material’s toughness makes it highly suitable for bolted and riveted connections in building and bridge skeletons.
  • » Surface Treatment Receptivity: The clean plate surface is an excellent substrate for industrial primers, epoxy coatings, or galvanizing to enhance long-term corrosion resistance.
