Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
JIS G4305 SUS309S (JIS G4305:2012) and EN 10088-1 1.4401 (EN 10088-1:2014) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4305 SUS309S is typically used for cold-rolled stainless steel plates, sheet and strip, while EN 10088-1 1.4401 is commonly used for marine, chemical processing, pharmaceutical equipment.
JIS G4305 SUS309S is defined under Japanese Industrial Standards (JIS), originating from Japan, while EN 10088-1 1.4401 is defined under European Standard (EN), originating from Europe.
As per chemical composition, JIS G4305 SUS309S vs EN 10088-1 1.4401 is a 62.6% match.
As per mechanical properties, the match is 50%.
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.
