Close Alternative — 84.2% match
based on chemical composition and mechanical property overlap.
EN 10088-1 X4CrNiCu18-7 (EN 10088-1:2023) and JIS G4304 SUS301L (JIS G4304:2021) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-1 X4CrNiCu18-7 is defined under European Standard (EN), originating from Europe, while JIS G4304 SUS301L is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, EN 10088-1 X4CrNiCu18-7 vs JIS G4304 SUS301L is a 84.2% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 84.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
