ASTM A283 Grade C Steel Plates

High-quality carbon structural steel plate produced to ASTM A283 Grade C specifications. A283 Grade C is a general-purpose structural steel widely used where moderate strength and good weldability are required; it is broadly equivalent to EN S235JR / S235J2, JIS SS400 / SM400 and DIN ST37-2.

Key features

• Conforms to ASTM A283 Grade C chemical and mechanical requirements for carbon structural plate.
• Supplied in flat plate form with processing options including cutting, edge preparation and surface pretreatment to customer requirements.
• Typical customization and quality services available: heat treatment, transverse (Z-direction) property control, Charpy impact testing, non-destructive testing (UT/MT/PT), chemical analysis and other factory or third-party inspections.
• Commonly stocked and offered alongside related grades (A283 Gr A, Gr B, Gr D) to meet a range of strength and toughness needs.

Industrial applications

Ideal for general structural and engineering uses where cost-effective, weldable carbon plate is required. Typical applications include:

• Buildings, bridges and structural components
• Boiler and pressure vessel structures (where permitted by design codes)
• Shipbuilding, offshore platforms and marine components
• Fabrication of frames, supports, molds and heavy machinery parts
• Pipelines and general fabrication projects

Supply, packaging and documentation

• Typical lead time: 15–30 days (subject to order size and processing).
• Export and domestic packing options available to protect material during transport.
• Mill Test Certificates (MTC) and inspection documentation can be provided on request; third-party inspection can be accommodated.

Why choose this grade

A283 Grade C balances cost, weldability and formability for many structural applications. For purchasers seeking a reliable, ASTM-spec carbon structural plate with flexible processing and inspection options, this grade is a practical choice for fabrication and construction projects.

For ordering, specify required dimensions, surface finish, any heat treatment or testing requirements, and quantity to obtain a tailored quotation and lead time.
