Equivalent Grades for SA514 Grade E
SA514 Grade E is a specific quenched and tempered alloy steel with enhanced atmospheric corrosion resistance. Its "equivalents" depend on whether you are matching its mechanical strength, corrosion resistance, or both.
ASTM A514 Grade E corresponds to international quenched and tempered high-strength steels, reflecting its composition (e.g., high Cr-Mo for toughness) and properties (yield ~620-690 MPa, tensile 690-895 MPa, enhanced low-temp impact). Listings are limited to direct equivalents for structural uses. The table below covers major standards per country/region, focusing solely on precise matches.

How to Choose Equivalent Grades: Decision Guide
| If your requirement is... | And the governing code is... | Then specify... |
|---|---|---|
| 100 ksi strength + Toughness | European (Eurocode) | EN 10025-6 S690QL |
| 100 ksi + Corrosion Resistance | US / AASHTO (for bridges) | ASTM A709 Grade 100W |
| Corrosion Resistance + Moderate Strength | US / General Construction | ASTM A588 Grade K (Plate) |
| General 100 ksi Q&T Steel | International / Not code-bound | ASTM A514 Grade F (the more common grade, but loses corrosion resistance of Grade E) |
Important Note on SA514 Grade E's Corrosion Resistance
Its corrosion resistance (~2x carbon steel) is less than that of dedicated weathering steels like A588 or A709-W (~4-6x). Grade E is often selected for applications where some improvement over plain steel is beneficial, but the primary driver is its high strength and hardenability in thicker sections.
Summary: There is no perfect, single international equivalent for SA514 Grade E. The closest matches are A709 Grade 100W (for bridges) or S690QL . Always base the final selection on certified Mill Test Reports to verify the specific properties your design requires, especially if corrosion resistance is a key factor.
