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 485 is a high-strength carbon steel plate grade under ASTM/ASME A516 standards, developed for boilers, heat exchangers, and high-pressure vessels.
It is especially recommended for critical refinery, petrochemical, and power plant equipment where strength, toughness, and reliability cannot be compromised.

| Property | Typical Value | Notes |
|---|---|---|
| Tensile Strength | 620–760 MPa | Higher strength than Gr 70 |
| Yield Strength | ≥ 485 MPa | Enhanced structural stability |
| Elongation | 17–20% | Maintains ductility for fabrication |
| Impact Tested | -20°C (CVN) | Available on request for sub-zero projects |
These properties make SA 516 Gr 485 a premium choice for demanding, high-pressure environments.
| 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 |
Clean chemistry with controlled low sulfur and phosphorus ensures resistance to cracking and improved weldability.
SA 516 Gr 485 is a high-strength grade under ASTM A516 / ASME SA516 standards, specifically designed for pressure vessels.
