When you’re building boilers, storage tanks, or pressure vessels, one wrong steel grade can sink an entire project. Cracks, rejections, or late deliveries don’t just cost money — they cost credibility and safety.
That’s why smart buyers across refineries, power plants, and fabrication yards turn to SA516 Gr 70 plates. This ASTM/ASME-approved grade isn’t just a piece of steel — it’s assurance that your vessel will perform under heat, pressure, and time.
SA516 Grade 70 is a carbon steel plate made for boiler and pressure vessel applications. It complies with ASTM A516 / ASME SA516 standards and is known for:
In simple words: If you are manufacturing a pressure vessel, heat exchanger, or industrial boiler, SA516 Gr 70 is the most demanded grade worldwide because it combines strength, safety, and economy.
Every engineer knows: buying cheap steel plates can be the most expensive mistake.
SA516 Gr 70 solves these pains:
That’s why boiler makers from India to the Middle East specify only SA516 Gr 70 instead of rolling the dice with unproven grades.
When pressure rises, you can’t afford uncertainty. SA516 Gr 70 plates give engineers confidence with mechanical properties that never compromise:
| Property | Value (Typical) | Why It Matters |
|---|---|---|
| Tensile Strength | 485–620 MPa | Ensures plates don’t rupture under load |
| Yield Strength | Min 260 MPa | Prevents permanent deformation |
| Elongation | 17–21% | Provides ductility for forming & welding |
| Impact Tested | -20°C (optional) | Guarantees toughness in low temperatures |
| Hardness (BHN) | ≤ 250 | Balanced hardness for weldability |
These numbers aren’t just technical specs — they are the reason refineries sleep at night knowing their boilers won’t fail.
The chemistry behind SA516 Gr 70 is what makes it reliable in critical environments:
| Element | % Range |
|---|---|
| Carbon (C) | ≤ 0.27 |
| Manganese (Mn) | 0.79–1.30 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
| Silicon (Si) | 0.13–0.45 |
Low phosphorus & sulfur mean reduced risk of cracks.
Balanced manganese ensures toughness & weldability.
Controlled carbon levels give strength without brittleness.
This balance is why classification societies, auditors, and end-users demand SA516 Gr 70 for pressure vessel fabrication.
Buyers’ Pain: “Will this plate meet my project’s code?”
That’s the first question every EPC, consultant, or auditor asks.
SA516 Gr 70 plates are approved worldwide under multiple standards:
No matter which country your project is in, SA516 Gr 70 matches global codes, reducing risks of rejection or redesign.
Buyer Frustration: Calling five suppliers for the right thickness and still not finding stock.
We solve this by offering ready plates in standard + custom dimensions:
Whether you need a 10 mm normalized plate for a boiler shell or a 50 mm thick NACE plate for a crude oil tank, we deliver without delays.
Pain Point: Choosing the wrong treatment can lead to brittle welds or failed toughness tests.
We supply SA516 Gr 70 in multiple heat treatment conditions:
Consulting Tip: If you are supplying to GCC refineries, always specify Normalized (N) condition — it’s mandatory for most refinery audits.
Real Buyer Fear: “Will the plate crack during bending or fail during welding?”
SA516 Gr 70 is designed for easy fabrication:
Engineers choose SA516 Gr 70 because it saves fabrication time and reduces wastage, meaning faster project delivery.
Too many projects fail because buyers unknowingly purchase uncertified, re-rolled, or old stock plates from traders.
We eliminate that risk by offering:
Our difference? We don’t just sell plates, we protect your project from shutdown risks.
To cover every application, we keep stock of the most demanded variants:
This ensures you never lose a contract because the required variant wasn’t available.
Buyer Fear: “Will my supplier be able to deliver internationally, with paperwork and packing intact?”
From GCC refineries to African power plants and Southeast Asian fabrication yards, our SA516 Gr 70 plates are trusted across the globe.
Every shipment is packed in seaworthy wooden pallets, edge-protected, shrink-wrapped, and fumigated — because export failures cost more than freight.
Too many buyers overpay or order the wrong variant simply because no one explained it clearly. Here’s a consultant’s checklist:
Pro tip: Always ask for EN 10204 3.2 certification if the plate goes into critical refineries or EPC projects.
Buyer Pain: “How do I know I won’t receive fake or non-traceable steel?”
Every plate is backed by:
Because authentic certification saves you from insurance issues, shutdown penalties, and project rejections.
Gr 70 has higher tensile strength and is preferred for more demanding applications.
Price depends on thickness, certification (NACE/HIC), and delivery terms. Contact us for the latest rate.
