SA 516 Grade 70 Equivalent Grades: IS 2002, EN and JIS Standards Compared
SA 516 Grade 70 is the world's most widely specified pressure vessel quality steel, but Indian fabricators and international project teams frequently need to know its equivalents in local or alternate standards — particularly IS 2002 for domestic boiler projects. This guide compares SA 516 Grade 70 against IS, EN, and JIS designations.
What is SA 516 Grade 70?
SA 516 Grade 70 (or ASTM A516 Grade 70) is a Pressure Vessel Quality (PVQ) carbon steel plate offering a strong combination of strength and notch toughness for moderate-to-lower-temperature service. It carries a tensile strength of 485-620 MPa and minimum yield strength of 260 MPa, and is the default material specification for boilers, heat exchangers, and gas storage tanks worldwide.
IS 2002 Grade 2: The Indian Equivalent
For projects governed by Indian codes — particularly those requiring Indian Boiler Regulations (IBR) certification — IS 2002 Grade 2 is the closest domestic equivalent, sharing a similar strength class (265 MPa minimum yield, 410-560 MPa tensile). It is not chemically identical to SA 516 Grade 70, but serves the same functional role for pressure vessel and boiler fabrication within India.
EN 10028-2 P355GH: The European Equivalent
In Europe, EN 10028-2 P355GH is the pressure-vessel-quality reference standard closest to SA 516 Grade 70, sharing a comparable strength class for elevated-temperature service. The 'GH' suffix denotes suitability at elevated temperature, similar in intent to SA 516's own temperature service ratings.
JIS G3118 SGV480: The Japanese Equivalent
In Japan, JIS G3118 SGV480 is the standard pressure vessel steel grade comparable to SA 516 Grade 70, used similarly in boiler shells, heat exchangers, and pressure vessel fabrication across Japanese industry.
Why Exact Substitution Requires Engineering Sign-Off
Pressure vessel and boiler applications are safety-critical, and substituting one standard for another without formal engineering approval is not advisable even when the strength classes are similar. Always confirm the specific code requirements of your project (ASME, IBR, PED, etc.) and verify the actual Mill Test Certificate data — chemical composition, tensile properties, and impact toughness — before treating SA 516 Grade 70, IS 2002 Grade 2, P355GH, or SGV480 as interchangeable.
Conclusion
SA 516 Grade 70 corresponds broadly to IS 2002 Grade 2 in India, EN 10028-2 P355GH in Europe, and JIS G3118 SGV480 in Japan — all serving a similar pressure vessel role, but with their own chemical and code requirements.
