Strong Match — 96.5% match
based on chemical composition and mechanical property overlap.
EN 10088-1 X7CrNiAl17-7 (EN 10088-1:2023) and JIS G4305 SUS631 (JIS G4305:2012) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-1 X7CrNiAl17-7 is defined under European Standard (EN), originating from Europe, while JIS G4305 SUS631 is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, EN 10088-1 X7CrNiAl17-7 vs JIS G4305 SUS631 is a 96.5% 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 96.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
