What Are ASTM A36 Plates?

ASTM A36 Plates are carbon steel plates designed for both structural and pressure vessel applications. Known for their excellent weldability, ductility, and strength, these plates are widely used in:

  1. Construction of bridges, buildings & heavy structures
  2. Boilers, storage tanks, and pressure vessels
  3. Offshore platforms, oil & gas projects
  4. General fabrication & machinery manufacturing

 If you need a steel plate that offers versatility, cost-effectiveness, and global acceptance, ASTM A36 is the right choice.

Why EPC Contractors, Fabricators & Engineers Prefer ASTM A36 Plates

Procurement teams and engineers often face issues like:

  • Unreliable suppliers delivering uncertified or mismatched plates
  • Late deliveries disrupting critical project timelines
  • Audit failures due to missing certifications or traceability

With Navgraha Steels INC, those risks disappear:

  • EN 10204 3.1/3.2 certified supply → Full traceability guaranteed
  • IBR approval & third-party inspection → No audit rejections
  • Ex-stock & mill fresh supply → Ready for both urgent and long-term projects
  • Global logistics expertise → Fast exports to GCC, Africa & Asia-Pacific

That’s why project managers, QA teams, and engineers worldwide choose Navgraha for ASTM A36 Plates.

Mechanical Properties That Ensure Structural Strength & Reliability

Property Typical Value Why It Matters
Tensile Strength 400–550 MPa Withstands structural & pressure loads
Yield Strength Min 250 MPa Prevents deformation under stress
Elongation 20–23% Provides ductility for forming & welding
Impact Resistance -20°C Tested Reliable performance in low temperatures
Hardness (BHN) ≤ 200 Allows easy machining & fabrication

These mechanical properties make ASTM A36 Plates strong, safe, and fabrication-friendly — suitable for critical structural and boiler applications.

Chemical Composition – Balanced Carbon Steel for Welding & Durability

Element % Range Purpose
Carbon (C) ≤ 0.25 Strength + good weldability balance
Manganese (Mn) 0.60–1.20 Adds toughness & ductility
Phosphorus (P) ≤ 0.04 Controlled for reducing brittleness
Sulfur (S) ≤ 0.05 Kept low to avoid cracking
Silicon (Si) 0.10–0.40 Improves strength & resistance

The balanced chemistry of ASTM A36 Plates ensures excellent weldability, structural performance, and durability in diverse industrial applications.

International Standards & Equivalent Grades of ASTM A36 Plates

Our ASTM A36 Plates are recognized across industries because they align with international equivalents, making cross-border procurement seamless:

This flexibility ensures plates are ready for structural, offshore, or boiler applications without compromising safety.

Fabrication & Processing Advantages of ASTM A36 Plates

Fabricators prefer ASTM A36 because it saves both time and cost in workshops:

  • Excellent weldability with SMAW, MIG, TIG & SAW processes
  • Smooth forming, rolling & bending with minimal risk of cracks
  • Compatible with CNC plasma, laser & waterjet cutting
  • Low hardness for easier machining and stress-free fabrication
