Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10025-3 S420N (EN 10025-3:2019) and GOST 19281 09G2S (GOST 19281-2014) are both steel grades.
Both fall under the Structural Steel category.
EN 10025-3 S420N is defined under European Standard (EN) (Europe).
As per chemical composition, EN 10025-3 S420N vs GOST 19281 09G2S is a 65.1% match.
As per mechanical properties, the match is 21.1%.
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.
