💡 Practical Difference in Use
Use ASTM A516 Grade 60 when: moderate tensile strength is sufficient, and cost-effectiveness with good weldability is a priority.
→ Example: medium-pressure boilers, storage tanks, heat exchangers, and welded pressure vessels.
Use ASTM A516 Grade 70 when: higher tensile strength, better pressure handling, and enhanced notch toughness are required.
→ Example: high-pressure boilers, heavy-duty pressure vessels, industrial steam drums, and high-temperature equipment.
Use Other Boiler Grades (e.g., A515/A285) when: specific temperature ranges, fabrication needs, or material flexibility is required beyond A516 capabilities.
→ Example: low-pressure vessels, moderate-temperature service, and applications requiring different carbon steel compositions.
