A516 Grade 70 is a carbon steel pressure vessel plate known for its high strength, notch toughness, and reliable weldability. It is widely used in:
It complies with ASTM A516 / ASME SA516 standards, designed for moderate and lower temperature service.
Available in normalized, as-rolled, or stress-relieved conditions, A516 Gr 70 plates can be supplied under:
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.27 |
| Manganese (Mn) | 0.85–1.20 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
| Silicon (Si) | 0.13–0.45 |
Note: Lower carbon content ensures excellent weldability.
| Property | Value (Typical) |
|---|---|
| Yield Strength (min) | 260 MPa (37 ksi) |
| Tensile Strength | 485–620 MPa (70–90 ksi) |
| Elongation (200 mm) | ≥ 17% |
| Elongation (50 mm) | ≥ 21% |
| Impact Toughness | ≥ 20 Joules @ -20°C |
| Hardness (Brinell) | 140–180 HB (typical) |
Plates are typically normalized to improve toughness.
| Specification | Range |
|---|---|
| Thickness | 6mm to 150mm |
| Width | Up to 3000mm |
| Length | Up to 12000mm |
| Tolerances | As per ASTM A20/A20M |
| Finish | Hot rolled / Normalized |
Optional: Bevelled edges, ultrasonic tested (UT), shot-blasted, and primer coated available.
All A516 Gr 70 plates from Hindustan Steel Corporation are supplied with:
Optional Testing: PWHT simulation, Charpy impact, flattening, tensile, hardness.
We supply A516 Gr 70 steel plates to:
Yes, especially in normalized condition with proper impact testing.
