ASTM A516 Grade 60 and Grade 70 are among the most trusted boiler-quality steel plates used for pressure vessels, steam boilers, heat exchangers, and industrial tanks. At Hindustan Steel Corporation, we supply these plates with precise thickness tolerance, heat-treated surfaces, and full traceability — ready for both Indian and global fabrication standards. Our plates conform to the ASME/ASTM A516 specification, ensuring high strength at low temperatures, excellent weldability, and resistance to brittle fracture.
Whether you’re sourcing for IBR-certified boiler projects or ASME-compliant pressure vessel fabrication, A516 Gr 60/70 plates deliver the toughness and reliability your industry demands.
ASTM A516 is a specification from ASTM International that covers carbon steel plates for moderate- and lower-temperature service in welded pressure vessels. The grade is divided primarily into:
These plates are normalized or stress-relieved to improve notch toughness, especially for petrochemical, power generation, and gas processing sectors. They are commonly found in:
A516 plates are widely used in industries where internal pressure, elevated temperatures, and corrosion exposure are a concern. Some key applications include:
We also supply HIC-tested and IBR-certified variants for highly regulated environments.
| Property | A516 Gr 60 | A516 Gr 70 |
|---|---|---|
| Yield Strength (min) | 260 MPa | 275 MPa |
| Tensile Strength (MPa) | 415–550 | 485–620 |
| Elongation (%) | 21–23% | 17–21% |
| Impact Toughness | Good (Notch tested) | Higher at low temp |
| Thickness Availability | 6mm to 150mm | 6mm to 150mm |
Both grades exhibit excellent weldability, notch toughness, and formability. Grade 70 is preferred where higher tensile strength is essential, especially in high-pressure and low-temperature service.
ASTM A516 falls under the ASME Section II Part A standards for pressure vessel plates. The material complies with stringent specifications for strength, notch toughness, and formability, making it globally accepted across industrial fabrication.
Here are some equivalent standards and close international grades:
| Standard | Equivalent Grades |
|---|---|
| ASME | SA516 Gr 60 / SA516 Gr 70 |
| EN 10028 | P265GH (Gr 60) / P355GH (Gr 70 approx.) |
| DIN | HII / 17Mn4 |
| IS (India) | IS 2041 Grade 265 / 275 |
| JIS (Japan) | SB410 / SB450 |
We can also provide dual-certified A516 Gr 60/70N plates (normalized), ensuring compatibility across multiple codes and buyer requirements.
At Hindustan Steel Corporation, we stock A516 Gr 60 and Gr 70 plates in a wide range of thicknesses and sizes — suitable for cut-to-length and custom applications.
Available Range:
We also offer custom-sized blanking and CNC profile cutting for vessel heads, tubesheets, and flanges based on your pressure vessel drawing or fabrication plan.
A516 Gr 60/70 plates are typically supplied in the following heat treatment conditions:
For HIC-resistant or sour service plates, we offer HIC-tested A516 Gr 70N with simulated PWHT and microstructure verification. These are recommended for hydrocarbon, hydrogen sulfide, or ammonia-rich environments.
ASTM A516 plates offer superior machinability and weldability, especially when normalized. Here’s how to work with them effectively:
We supply plates with bevelled edges, ID stamping, ultrasonic testing (UT), and full mill traceability, making your fabrication process easier and compliant with codes like IBR, ASME, and PED.
We understand the criticality of boiler plate reliability — our supply chain is designed for zero-defect, high-performance delivery to EPCs, pressure vessel fabricators, and OEMs.
If your project demands different specs, consider these grades:
We also offer HIND Boiler Plates, our house brand of normalized and tested pressure vessel steel, customized for Indian fabrication needs.
Hindustan Steel Corporation exports A516 Gr 60/70 boiler plates to over 30 countries, with a strong presence in:
Export Packaging Includes:
We ensure zero transit corrosion with marine-grade packaging — fit for port handling and direct site delivery.
Here’s how to select the right grade and plate configuration for your project:
| Factor | Recommendation |
|---|---|
| Higher strength & pressure | Go for A516 Gr 70 (485–620 MPa UTS) |
| Cost-sensitive project | A516 Gr 60 offers great balance |
| Sub-zero application | Choose Normalized (Gr 70N) with Charpy V test |
| Sour/Acidic Media | Use HIC-tested SA516 Gr 70N + NACE MR0175 |
| Indian boiler compliance | Ask for IBR Approved plates (Form III) |
Still unsure? Share your vessel drawing or spec sheet — our team will match the right plate configuration with mill TDC and lead time clarity.
Our A516 Grade 60/70 boiler quality plates are fully certified with:
Mill Test Certificate (EN 10204 3.1 / 3.2)
