Strong Match — 85.6% match
based on chemical composition and mechanical property overlap.
EN 10088-1 X6CrNiCuS18-9-2 (EN 10088-1:2023) and JIS G4304 SUS303 (JIS G4304:2021) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-1 X6CrNiCuS18-9-2 is defined under European Standard (EN), originating from Europe, while JIS G4304 SUS303 is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, EN 10088-1 X6CrNiCuS18-9-2 vs JIS G4304 SUS303 is a 85.6% 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 85.6%.
Frequently Compared With EN 10088-1 X6CrNiCuS18-9-2:
