High Tensile Steel Plates for Pressure Vessels & Autoclaves
What Are Pressure Vessel-Grade High Tensile Plates?
Pressure vessel-grade steel plates are engineered to withstand high internal pressures, elevated temperatures, and aggressive contents such as gases, chemicals, and steam. These plates must offer superior notch toughness, weldability, and fatigue resistance. Hindustan Steel Corporation supplies certified high tensile boiler plates with guaranteed mechanical strength, chemical stability, and global compliance.
Our pressure-grade steel plates are widely used in:
Plates are also used in off-shore rigs and energy processing systems where rupture or fatigue risks are critical.
| Grade | Yield Strength | Tensile Strength | Elongation | Impact Test |
|---|---|---|---|---|
| SA 516 Gr 70 | 260 MPa | 485–620 MPa | ≥21% | 27J @ -20°C |
| ASTM A537 Cl 1 | ≥250 MPa | 485–620 MPa | ≥20% | 27J @ -50°C (typ.) |
| IS 2062 E350BR | ≥350 MPa | 490–630 MPa | ≥22% | 27J @ -20°C |
| S355J2+N | ≥355 MPa | 470–630 MPa | ≥20% | 27J @ -20°C |
| EN 10028 P355NH | ≥355 MPa | 490–620 MPa | ≥22% | 27J @ -40°C |
For high-pressure and H2S environments, we also supply NACE-compliant or HIC-tested plates.
| Element | Range (SA 516 Gr 70) |
|---|---|
| C | 0.27 max |
| Mn | 0.79 – 1.30 |
| Si | 0.13 – 0.45 |
| S, P | ≤0.035 |
Clean chemistry improves weldability and reduces risk of brittle fracture under pressure.
We stock and export pressure vessel-grade plates as per:
Plates come with EN 10204 3.1 MTC or third-party inspection reports.
We supply plates in following conditions:
We also offer cut-to-dome, rolled shell, and primer-coated plate delivery.
We regularly export to:
Packing: VCI-coated, film-wrapped, edge-protected for sea freight.
| Use Case | Suggested Grade |
|---|---|
| Steam Boiler | SA 516 Gr 70 (N) |
| Chemical Pressure Vessel | A537 Cl 1 / P355NH |
| LPG Bullets / Spheres | SA 537 Cl 2 (Q+T) |
| Low-Pressure Tanks | IS 2062 E350BR |
| Ammonia/Urea Loop | HIC Tested P355NH |
We help EPCs and OEMs select material based on pressure, temperature, media, and design code.
All plates come with:
It’s a carbon steel plate normalized for high-temperature pressure service.
Yes. It’s fully weldable with standard procedures and low-hydrogen electrodes.
Typically around 260 MPa for Gr 70, depending on thickness and heat treatment.
It’s steel tested for hydrogen-induced cracking—essential for sour service.
A537 is quenched + tempered with higher impact strength vs. normalized A516.
Yes. We can supply IBR-certified plates with Form IIIC.
Plates from 5 mm to 150 mm thickness, with widths up to 3000 mm.
E350BR can be used for low-pressure or atmospheric tanks.
SA 537 Cl 2 or A516 Gr 70, depending on pressure and temperature.
Yes. We can supply blasted and coated plates ready for fabrication.
27J @ -20°C for SA 516 Gr 70. HIC and low-temp plates offer better performance.
Yes. We offer custom CNC cuts, shell circles, bevels, and more.
Yes. We supply plates compliant with PED 2014/68/EU for EU projects.
We dispatch cut-size or full plates within 3–5 working days.
