Without NACE-certified steel:
At Navgraha Steels INC, Mumbai – Maharashtra – India, we supply SA516 Gr 70 NACE Certified Sheets that:
With us, you don’t just buy steel sheets — you secure your project against failure, audits, and shutdown risks.
SA516 Gr 70 NACE Sheets are boiler and pressure vessel quality carbon steel sheets tested and certified for sour gas service as per NACE MR0175/MR0103.
They are ideal for:
In short, these sheets are mandatory for any project handling H₂S or sour service environments.
Procurement teams often ask:
With Navgraha Steels INC supply, the answer is always YES:
That’s why leading EPCs and refineries trust Navgraha Steels INC for NACE-certified sheets.
| Property | Typical Value | Why It Matters |
|---|---|---|
| Tensile Strength | 485–620 MPa | Handles refinery & boiler pressures |
| Yield Strength | Min 260 MPa | Ensures reliability under heavy loads |
| Elongation | 17–21% | Allows safe forming & bending |
| Impact Resistance | Up to -20°C | Prevents brittle cracking at low temp |
| Hardness (BHN) | ≤ 250 | Ensures weldability & machinability |
These properties make them fit for refinery-grade sour service applications where failure is not an option.
| Element | % Range | Why Controlled? |
|---|---|---|
| Carbon (C) | ≤ 0.21 | Improves weldability, avoids brittleness |
| Manganese (Mn) | 0.55–1.20 | Adds strength while keeping toughness |
| Phosphorus (P) | ≤ 0.020 | Extra low → prevents sulfide cracking |
| Sulfur (S) | ≤ 0.010 | Extra low → resists hydrogen-induced corrosion |
| Silicon (Si) | 0.13–0.45 | Stability during fabrication |
NACE-compliant chemistry = ultra-low P & S → makes these sheets resistant to SSC and HIC in sour service.
Our SA516 Gr 70 NACE Certified Sheets are tested and manufactured as per international codes:
With NACE MR0175/MR0103 certification, these sheets are accepted in refineries, sour service units, and offshore projects worldwide.
