Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10025-3 S420N (EN 10025-3:2019) and ASTM A283C (ASTM A283) are both steel grades.
Both fall under the Structural Steel category.
EN 10025-3 S420N is defined under European Standard (EN), originating from Europe, while ASTM A283C is defined under ASTM International, originating from United States.
As per chemical composition, EN 10025-3 S420N vs ASTM A283C is a 58.8% match.
As per mechanical properties, the match is 0%.
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.
