Boiler & Pressure Vessel Steel — Frequently Asked Questions
ASTM A516 plates (SA-516) are primarily intended for service where improved notch toughness (resistance to brittle fracture) is essential, typically in moderate to low-temperature service. ASTM A515 plates (SA-515) are intended for service exclusively at high temperatures (e.g., non-corrosive boiler drums) and do not have the same mandatory requirements for low-temperature impact testing as A516.
A516 Gr 70 is the most widely used pressure vessel steel due to its excellent combination of high tensile strength (70-90 ksi) and superior low-temperature notch toughness. This makes it suitable for pressure equipment handling gases and liquids across a wide temperature spectrum, especially in environments where impact loading is a concern.
The ASME Boiler and Pressure Vessel Code equivalent to ASTM A516 is ASME SA-516. When used for pressure vessels, the material is certified as ASME SA-516 Gr 70 (or 60/55) to meet the strict requirements for safety and integrity outlined in the ASME code for pressurized equipment fabrication.
Yes. For pressure vessels handling wet Hâ‚‚S (sour service) environments, plates must meet NACE MR0175 and undergo HIC (Hydrogen Induced Cracking) testing. We specialize in sourcing and supplying NACE-compliant, HIC-tested A516 Gr 70 plates to ensure they can withstand Sulphide Stress Corrosion Cracking (SSCC).
