Other Information
Comparable Standards:
ASME SA516 Grade 55 (identical to ASTM A516 but for ASME Boiler and Pressure Vessel Code use)
EN 10028-2 P265GH (European equivalent)
Comparison with Other Grades:
The key grades of ASTM A516 (55/60/65/70) are primarily distinguished by their tensile strength:
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Key Use Case |
| A516 Grade 55 | 380-515 | 205 | Low-pressure applications |
| A516 Grade 60 | 415-550 | 220 | Intermediate pressure |
| A516 Grade 65 | 450-585 | 240 | Higher pressure |
| A516 Grade 70 | 485-620 | 260 | High-pressure & low-temp |
Heat Treatment:
Typically supplied in normalized condition for improved toughness.
May also be supplied as hot-rolled or stress-relieved depending on application requirements.
Advantages:
1. Good weldability and formability
2. Suitable for low-temperature service (down to -29°C / -20°F)
3. Cost-effective for moderate-pressure applications
