Close Alternative — 73.3% match
based on chemical composition and mechanical property overlap.
EN 10346 S450GD (EN 10346:2015) and ASTM A572 Gr.65 (ASTM A572) are both steel grades.
Both fall under the Structural Steel category.
EN 10346 S450GD is typically used for higher-strength continuous hot-dip galvanized structural steel strip/sheet; roll-formed and cold-formed high-strength structural sections, purlins, roofing and cladding requiring corrosion protection, while ASTM A572 Gr.65 is commonly used for used for bridges, buildings, transmission towers, construction equipment, offshore structures, and structural members..
EN 10346 S450GD is defined under European Standard (EN), originating from Europe, while ASTM A572 Gr.65 is defined under ASTM International, originating from United States.
As per chemical composition, EN 10346 S450GD vs ASTM A572 Gr.65 is a 93.2% match.
As per mechanical properties, the match is 33.3%.
Combined, this makes them a close alternative overall at 73.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
