Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10025-3 S420N (EN 10025-3:2019) and ASTM A1008 SS Grade 80 (ASTM A1008) 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 A1008 SS Grade 80 is defined under ASTM International, originating from United States.
As per chemical composition, EN 10025-3 S420N vs ASTM A1008 SS Grade 80 is a 61.4% 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.
