ASTM A283 Grade C – Low Carbon Steel Plate for Structural & Tank Applications

ASTM A283 Grade C Steel Plate – Low Carbon, Easy-to-Form & Structurally Reliable

ASTM A283 Grade C is a commercial-grade low-carbon structural steel plate known for its excellent formability, weldability, and cost-efficiency in non-critical load-bearing applications. Hindustan Steel Corporation supplies A283 Gr C plates that meet ASTM, ASME, and equivalent global standards, ideal for tank fabrication, base plates, ducts, bridges, and non-pressure structural components.

For buyers looking to match DSQ steel or IS 2062 E250A in formability—but want globally accepted mechanical tolerances—A283 Gr C offers the perfect alternative.

What Is ASTM A283 Grade C Steel? Voice-Search Friendly Answer

ASTM A283 Grade C is a standard carbon-manganese steel plate under ASTM A283 specification, designed for moderate strength and excellent bendability. It’s often used in fabrication where structural toughness isn’t critical but consistent shaping, cold forming, and weld compatibility are key.

With a yield strength of ~205 MPa and tensile strength up to 415 MPa, A283 Gr C offers a soft working profile—ideal for press-formed tanks, structural frames, and general steel construction.

Applications – Where A283 Gr C Plates Are Used

ASTM A283 Grade C plates are preferred in:

  • Tank and vessel fabrication
  • Ducting and chimney work
  • Bridge platforms and plates
  • Welded base frames and brackets
  • Automotive chassis
  • Mild structural & construction segments
  • Components requiring light forming or bending

Its formable temper, clean surface, and cost-efficiency make it a practical replacement for DSQ or IS 2062 E250 in export-ready builds.

Mechanical Properties of ASTM A283 Grade C

Property Value
Yield Strength (min) 205 MPa
Tensile Strength 380–515 MPa
Elongation (% in 200 mm) 20–24%
Hardness (BHN) ~120–140
Modulus of Elasticity ~200 GPa
Weldability Excellent
Cold Bending Very Good

These characteristics mirror DSQ plate behavior, making A283 Gr C a preferred global alternative when IS 2062 isn’t available or ASTM certification is required.

ASTM A283 Grade C Standards, Equivalents & Material Mapping

ASTM A283 Grade C is part of the A283 specification that covers four grades (A, B, C, D) of carbon steel plates. Grade C offers a balanced mix of strength and formability, making it ideal for non-critical structures.

Here’s how it compares with Indian, European, and other global equivalents:

Standard Equivalent Grade
ASTM A283 Grade C IS 2062 E250A (approx.)
EN 10025 S235JR / S235JO
DIN St37-2
JIS SS400
ASME SA 283 Gr C
AISI 1015 (chemical similarity)

Buyer Note: While DSQ and A283 Gr C are not listed as direct equivalents, both offer dead-soft, low-strength forming grades for light to moderate stress fabrication.

Available Sizes, Thickness Range & Mill Supply Conditions

At Hindustan Steel Corporation, we supply ASTM A283 Gr C plates with the following availability:

  • Thickness: 3 mm to 50 mm
  • Width: 1000 mm to 2500 mm
  • Length: 2000 mm to 12000 mm
  • Supply Conditions: Hot Rolled (HR), Annealed (on request), Stress-Relieved (custom projects)
  • Edge Finish: Mill edge, sheared, or bevelled

We also offer cut-to-size supply, hole punching, surface prep, and flattening services as per your drawings.

Heat Treatment, Normalizing & Structural Temper Options

  • Standard Condition: Supplied as hot rolled or as-rolled
  • Optional Heat Treatment: Can be normalized or annealed for enhanced ductility or stress relief
  • Stress Relieving: Available for large tanks and precision structural applications
  • Weld Zone Softening: Minimal; welding does not affect structural profile

A283 Grade C is not a quenched and tempered steel. Its strength lies in workability, not toughness—ideal for shape-heavy designs and tanks.

Fabrication Tips – Machining, Welding, Cold Bending

A283 Gr C is a fabricator’s steel—built for processes like:

  1. Machining: Compatible with standard tools, low tool wear
  2. Welding: SMAW, TIG, MIG—no preheat needed
  3. Cold Work: Excellent cold rolling and press bending
  4. Punching / Hole Cutting: Burr-free edge cutting possible on CNC/saw
  5. Galvanizing / Pickling Compatibility: Yes

Recommendation: Always use a minimum internal bend radius of 2.5–3x plate thickness for cold bends on A283 C grade.
