Strong Match — 90.5% match
based on chemical composition and mechanical property overlap.
ASTM A959 409 (ASTM A959:2011) and JIS G4304 SUS410S (JIS G4304:2021) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 409 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while JIS G4304 SUS410S is commonly used for hot-rolled stainless steel plates and strips.
ASTM A959 409 is defined under ASTM International, originating from United States, while JIS G4304 SUS410S is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, ASTM A959 409 vs JIS G4304 SUS410S is a 90.5% 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 90.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
