Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10025-3 S355NL (EN 10025-3:2019) and CSA G40.21 400W (CSA G40.21-13 (R2023)) are both steel grades.
Both fall under the Structural Steel category.
EN 10025-3 S355NL is defined under European Standard (EN), originating from Europe, while CSA G40.21 400W is defined under Canadian Standards Association (CSA), originating from Canada.
As per chemical composition, EN 10025-3 S355NL vs CSA G40.21 400W is a 62.9% match.
As per mechanical properties, the match is 25%.
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.
