Navgraha Steels INC is a leading stockist and exporter of SA 516 Gr 415 Plates, Sheets & Coils, sourced from reputed mills including Sail, AMNS, JSPL, Evonith, Nippon Yakin, Outokumpu, Special Metals, VDM, and ATI. This high-strength boiler quality steel is engineered for moderate to high-pressure vessels, refineries, and petrochemical equipment. Buyers trust our supply chain for certified quality, IBR approvals, and export-ready documentation.
When it comes to boiler and pressure vessel projects, one mistake in choosing the wrong grade
One wrong sheet grade can mean audit rejection, sudden leaks, or costly shutdowns
In the pressure vessel industry, a wrong coil grade can mean audit failures, weld cracking
SA 516 Gr 415 is a carbon steel pressure vessel plate grade under the ASTM A516/ASME SA516 standard.
Preferred by EPC contractors and fabricators who need a balance of strength, weldability, and economy.

pressure vessels, separators, columns

steam drums, boilers, pressure tanks

reactors, urea plants, fertilizer equipment

storage tanks, scrubbers, sour service lines

ship boilers, onboard tanks

custom projects requiring higher strength than Gr 70
| Property | Value (Typical) | Notes |
|---|---|---|
| Tensile Strength | 550–700 MPa | Higher than Gr 70 |
| Yield Strength | ≥ 415 MPa | Ensures pressure vessel stability |
| Elongation | 18–21% | Balanced ductility for fabrication |
| Impact Tested | -20°C (Charpy) | Optional for sub-zero projects |
SA 516 Gr 415 is stronger than Gr 70, making it ideal for critical boilers and high-pressure applications
| Element | Max % (Typical) |
|---|---|
| Carbon (C) | 0.27–0.30 |
| Manganese (Mn) | 0.80–1.50 |
| Phosphorus (P) | 0.025–0.030 |
| Sulfur (S) | 0.010–0.015 |
| Silicon (Si) | 0.13–0.45 |
A low phosphorus & sulfur content improves weldability, while balanced carbon levels provide strength without compromising toughness.
SA 516 Gr 415 is covered under ASTM A516 / ASME SA516 for boiler & pressure vessel plates.
