Home > Our Products > Structural Steel Plates > Grade / Standard> ASTM A572 Gr 50 / Gr 60
Hindustan Steel Corporation supplies premium ASTM A572 Gr 50 and Gr 60 plates designed for structural and load-bearing applications requiring superior strength and formability. These low-alloy, high-strength steel plates are ideal for fabricators and EPC contractors working in infrastructure, bridges, towers, heavy machinery, and oil field structures.
We stock A572 plates in cut-to-size dimensions, mill-tested, and ready for both domestic and international dispatch with full certification.
ASTM A572 is a high-strength, low-alloy (HSLA) structural steel specification developed by ASTM International. It covers multiple strength levels (Grades 42, 50, 55, 60, and 65), with Grade 50 and Grade 60 being most commonly used.
Both grades offer minimum yield strengths of 345 MPa (Gr 50) and 415 MPa (Gr 60), making them reliable for demanding load-bearing environments.
A572 plates are engineered for structural integrity and weight optimization. They’re commonly used in:
Their high strength-to-weight ratio helps reduce structural mass while maintaining load capacity.
| Property | Grade 50 | Grade 60 |
|---|---|---|
| Yield Strength | ≥ 345 MPa (50 ksi) | ≥ 415 MPa (60 ksi) |
| Tensile Strength | 450–620 MPa | 485–650 MPa |
| Elongation (200mm) | ≥ 18% | ≥ 17% |
| Charpy Impact | 27J @ 0°C (optional) | 27J @ 0°C (optional) |
Chemical Composition (Typical):
These grades are commonly supplied in the as-rolled or normalized condition and offer excellent formability.
ASTM A572 is governed by the ASTM A572/A572M standard and categorized as a HSLA steel plate with higher strength and improved notch toughness. These plates are designed to meet structural performance in welded, riveted, or bolted constructions.
| ASTM Grade | Indian Equivalent | EN Equivalent | JIS Equivalent |
|---|---|---|---|
| A572 Gr 50 | IS 2062 E350 | EN 10025 S355J2 | SM490YB |
| A572 Gr 60 | IS 2062 E410 | EN S420 | SM490YA |
A572 Gr 50 is one of the most widely accepted international equivalents for IS 2062 E350 and is suitable for global procurement and export-oriented projects.
At Hindustan Steel, we maintain ready stock and custom supply of A572 Gr 50 and Gr 60 in:
We also offer CNC plasma cutting, beveling, and plate nesting based on BOQ or fabrication drawings.
A572 Gr 50 and Gr 60 offer superior fabrication flexibility due to:

Our in-house engineering support helps buyers make grade-equivalent decisions without compromise.
All A572 plates supplied by us are backed by:
We ensure full traceability, documentation, and heat number tracking from dispatch to site.
Gr 60 has higher yield (415 MPa) and tensile strength (up to 650 MPa) than Gr 50 (345 MPa), suitable for more demanding structures.
Carbon ≤ 0.23%, Mn ≤ 1.35%, P ≤ 0.04%, S ≤ 0.05%, Nb/V added for strength.
Yes. A572 Gr 50 ≈ IS 2062 E350, and Gr 60 ≈ IS 2062 E410, with better toughness and weldability.
Yes. Both grades offer excellent weldability, good bendability, and machining properties.
Approximately 485–650 MPa, making it suitable for dynamic loads and fatigue-prone applications.
Yes. We offer 27J impact-tested plates at 0°C and -20°C for bridge and offshore applications.
6 mm to 150 mm thick, up to 2500 mm wide, 12-meter standard lengths or cut-to-size.
Yes. All plates are supplied with MTCs, third-party inspection reports, and heat numbers.
Yes, especially with primer coating or Q+T treatment. Gr 60 is preferred for extra toughness.
Defined under ASTM A572/A572M, available via ASTM.org or request from our technical team.
Yes, shot blasting and red oxide/zinc primer coatings available on request.
Thickness (mm) × 7.85 = weight in kg/m². E.g., 10mm = 78.5 kg/m².
Yes, A572 plates with CE-marked equivalents are available with proper documentation.
Yes. Small quantities, urgent deliveries, and custom cut sizes are all available.
