Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
JIS G4304 SUS420J1 (JIS G4304:2021) and EN 10088-1 1.4845 (EN 10088-1:2014) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4304 SUS420J1 is typically used for hot-rolled stainless steel plates and strips, while EN 10088-1 1.4845 is commonly used for furnace parts, heat exchangers, kiln components.
JIS G4304 SUS420J1 is defined under Japanese Industrial Standards (JIS), originating from Japan, while EN 10088-1 1.4845 is defined under European Standard (EN), originating from Europe.
As per chemical composition, JIS G4304 SUS420J1 vs EN 10088-1 1.4845 is a 62.8% match.
As per mechanical properties, the match is 0%.
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.
