Key Points for Engineers and Procurement Teams

• Direct Equivalent: Only ASME SA-517 Grade F is considered 100% interchangeable with ASTM A517 Grade F.
• Chemically Identical: A514 Grade F has the exact same chemical composition and mechanical properties as A517 Grade F, differing only in the intended application (structural vs. pressure vessel).
• HIC + NACE Versions: For sour service (HIC / NACE MR0175 / ISO 15156), Gangsteel supplies A517 Grade F HIC + NACE using the same base grade with enhanced cleanliness (low S, Ca-treated, controlled CE/PCM). No change in base equivalent is needed.
• International Substitution: When A517 Gr F is not locally available, P460QL1 or S690QL are the most common European alternatives, subject to project approval and additional testing.
•  

Gangsteel maintains a large inventory of ASTM A517 Grade F (including HIC and NACE compliant plates) in thicknesses from 6 mm to 150 mm, with full EN 10204 3.1/3.2 certification and supplementary requirements (HIC per NACE TM0284, hardness control, UT testing, etc.).

If you need a detailed chemical composition comparison, mechanical properties table, or assistance selecting the most suitable equivalent for your project, please contact Gangsteel directly. We provide technical support and competitive pricing for both standard and sour-service (HIC/NACE) versions of A517 Grade F.
