Pressure vessels operate under extreme internal pressures, high temperatures, and safety-critical environments — from boilers and reactors to LPG tanks and autoclaves. Choosing the right steel plate isn’t just about thickness, but about code compliance, impact strength, notch toughness, and weldability. Hindustan Steel Corporation supplies certified pressure vessel grade plates that comply with ASME, IBR, EN, and PED standards – with ready stock for domestic and export buyers.
What Makes a Plate Suitable for Pressure Vessels?
- Notch Toughness at Low Temperature
- Resistance to Brittle Fracture
- High Yield & Tensile Strength
- Weldability (No preheat required where possible)
- Code Compliance (ASME Sec II, EN 10028, IBR, PED)
Pressure vessel plates are usually killed steel, normalized or quenched-tempered, and undergo UT, impact, HIC/NACE, and hardness testing.
Typical Applications of Pressure Vessel Plates
- Steam Boilers and Economizers
- Heat Exchangers and Reactors
- LPG, Ammonia, or Cryogenic Tanks
- Air Receivers and Autoclaves
- Pharmaceutical, Fertilizer, and Oil Refineries
- Hydrogen Service (with HIC-resistant plates)
We help EPC contractors and OEMs meet project-specific standards with mill-certified plates in stock.

Heat Treatment Requirements for Pressure Plates
- A516 Gr 70: Supplied as-rolled or normalized
- 16Mo3, P355GH: Normalized delivery mandatory
- SA 387 Grades: Quenched & tempered for high-temp use
For IBR applications: Normalizing + Stress relieving may be needed
We can arrange post-fabrication heat treatment certificates as required
Cutting, Welding & Fabrication Advice
- Plates can be CNC cut, beveled, and edge-prepped
- Preheating only needed for some high-alloy grades
- Good weldability across A516, P355, and IS 2002
- Use low hydrogen electrodes for best results
We provide fabrication-ready plates, saving time and effort at shop floor.

FAQs – Pressure Vessel Plate Selection & Supply
Is A516 Gr 70 suitable for high pressure?
Yes, it offers excellent notch toughness and strength for moderate to high pressure.
What is the Indian equivalent of ASTM A516?
IS 2002 Grade 2 is often considered the Indian equivalent.
Do I need impact-tested plates for all pressure vessels?
It depends on service temperature. For -20°C or lower, impact-tested plates like 3.1/3.2-certified are required.
Can you supply plates with IBR and PED both?
Yes — we offer dual-certification for projects involving multiple codes.
What is HIC-tested steel?
Plates tested for Hydrogen Induced Cracking, required in sour gas or chemical service.
Is UT testing mandatory?
For pressure vessels, UT (Ultrasonic Test) is highly recommended and often mandatory.
Which grade should I use for high-temperature service?
Use ASTM A387 or 16Mo3 – both are alloy steels suited for elevated temperatures.
Do you offer cut-to-size delivery?
Yes — we supply pre-cut, beveled, and edge-marked plates.
What’s the MOQ for export orders?
Export orders start from 5–10 tons, depending on destination and certification.
