Strong Match — 90.1% match
based on chemical composition and mechanical property overlap.
JIS G4304 SUS317LN (JIS G4304:2021) and EN 10088-1 X2CrNiMoN18-12-4 (EN 10088-1:2023) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4304 SUS317LN is defined under Japanese Industrial Standards (JIS), originating from Japan, while EN 10088-1 X2CrNiMoN18-12-4 is defined under European Standard (EN), originating from Europe.
As per chemical composition, JIS G4304 SUS317LN vs EN 10088-1 X2CrNiMoN18-12-4 is a 90.1% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 90.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
