Hindustan Steel Corporation is a leading stockist and exporter of ASTM A572 Grade 50 and A573 structural steel plates, widely used in bridges, offshore platforms, oil & gas, and pressure vessels. These grades offer an excellent blend of high yield strength, toughness, weldability, and durability, making them ideal for both structural and pressure-containing applications.
We supply cut-to-size A572 Gr 50 / A573 plates with mill TC, third-party inspection, and export packaging, ready for global infrastructure projects.
ASTM A572 Gr 50 is a high-strength, low-alloy (HSLA) structural steel, offering:
ASTM A573 is a structural quality plate used for pressure vessels, offering:
These grades conform to ASTM A6/A6M dimensional standards and can be substituted with S355JR, S420, or IS 2062 E350C in many cases.
Widely used across:
A573 plates are ideal for tank fabrication, boiler shells, and structural pressure components where moderate strength and impact resistance are critical.
| Grade | Yield Strength (MPa) | UTS (MPa) | Elongation (%) | Impact Toughness |
|---|---|---|---|---|
| A572 Gr 50 | ≥ 345 – 355 | 450 – 620 | ≥ 18 – 21 | 27J @ -20°C (on req) |
| A573 Gr 65 / 70 | ≥ 450 / 485 | 560 – 620 | ≥ 18 – 22 | 27J @ -20°C (typical) |
Both grades conform to ASTM specifications and align with global equivalents for easy substitution in international projects:
| ASTM Grade | Global Equivalent | Indian Equivalent |
|---|---|---|
| A572 Gr 50 | EN S355J2 / S420NL / S550MC | IS 2062 E350C |
| A573 Gr 70 | ASTM A516 Gr 70 (pressure use) | IS 2041 Gr 450 / SA 516 |
We stock ASTM A572 and A573 plates in standard and custom sizes:
Need drilled, slotted, or notched profiles? Upload your drawing — we’ll process it.
Both grades are suitable for low-temperature or cyclic load environments when tested as per ASTM A770.
| Process | Compatibility |
|---|---|
| Welding | MIG, TIG, SMAW (no preheat under 40 mm) |
| Bending/Forming | Cold bending up to 3× thickness |
| Machining | Clean surface finish, suitable for CNC / lathe |
| Drilling | High-speed drilling with standard bits |
| Pre-Heat | Required only for thick plates ≥ 50 mm |
We also provide weldability charts, WPS support, and test coupons on request.
We supply to bridges, refineries, shipyards, offshore yards, and tank fabricators across 5 continents.
In addition to A572 and A573, we stock:
We also support equivalent grade substitution for cross-border projects.
We supply ASTM A572 Gr 50 and A573 plates to clients across:
Export Supply Format Includes:
| Feature | ASTM A572 Gr 50 | ASTM A573 Gr 70 |
|---|---|---|
| Use Case | Structural steelwork | Pressure tanks / structural pressure use |
| Yield Strength | ~350 MPa | ~485 MPa |
| Weldability & Fabrication | Excellent | Excellent |
| Impact Toughness | Optional | Mandatory (Gr 70) |
| Codes | ASTM A6 / A572 | ASTM A573 / A770 |
Need both strength and toughness? A573 is ideal for hybrid structures and tank fabrication.
We deliver A572 / A573 plates with:
Documents are formatted per project spec and verified at dispatch
It’s used for pressure vessels, storage tanks, and structures requiring notch toughness.
A572 is structural HSLA; A573 offers better toughness for pressure applications.
Typically includes C ≤ 0.23%, Mn ≤ 1.35%, Si ≤ 0.40%, Cu, Cr, and Ni in small amounts.
Usually CE ≤ 0.42%, making it highly weldable.
Used in bridges, buildings, towers, crane booms, truck chassis, and offshore platforms.
Yes. A573 has good weldability and is often used in pressure tank fabrication.
Yes, Charpy-tested variants at -20°C or lower are available on request.
Yes. A572 Gr 50 ≈ S355J2 / IS 2062 E350C in mechanical properties.
Yes. A573 is often used in low-pressure boiler and storage tank shells.
