IS 2062 vs ASTM A36 – Are They Equivalent Steel Grades?

IS 2062 vs ASTM A36 – Quick Comparison for Buyers

Are you confused between IS 2062 and ASTM A36 steel plates?
Both are popular carbon steel structural grades, but are they truly equivalent? Let’s clear the confusion.

IS 2062 = Indian Standard
ASTM A36 = American Standard

If you’re buying for projects in India, UAE, Africa, or export markets, this comparison will help you choose the right material.

What is IS 2062 Grade A/B/C?

IS 2062 is an Indian standard for structural steel plates, issued by Bureau of Indian Standards (BIS).

Available Grades:

• Grade A (E250 A)
• Grade B (E250 B)
• Grade C (E250 C)

Common Applications:
Structural Fabrication
General Engineering
Bridges and Buildings
OEM Machine Parts

Applications Where HIND ARMOR 500 Hardness Matters

Where is this hardness range critical?

Each of these applications demands high surface hardness to ensure bullet deflection, absorption, and stopping ability.

What is ASTM A36?

ASTM A36 is an American standard structural steel plate, specified by ASTM International.

Applications:
Construction Frames
Bridges
Oilfield Skids
Fabrication of Base Frames and Supports

Mechanical Properties Comparison

Property	IS 2062 Grade B	ASTM A36
Yield Strength	Min 250 MPa	Min 250 MPa
Tensile Strength	410–580 MPa	400–550 MPa
Elongation	23% Min	20–23%
