Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10025-2 E335 (EN 10025-2:2019) and CSA G40.21 400A (CSA G40.21-13 (R2023)) are both steel grades.
Both fall under the Structural Steel category.
EN 10025-2 E335 is typically used for hot rolled products of structural steels, while CSA G40.21 400A is commonly used for atmospheric corrosion-resistant (weathering) structural steel; exposed bridge girders and structural members where high strength and weathering resistance are both needed.
EN 10025-2 E335 is defined under European Standard (EN), originating from Europe, while CSA G40.21 400A is defined under Canadian Standards Association (CSA), originating from Canada.
As per chemical composition, EN 10025-2 E335 vs CSA G40.21 400A is a 76.5% match.
As per mechanical properties, the match is 17.5%.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
