Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
JIS G4304 SUS440A (JIS G4304:2021) and ASTM A959 316H (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4304 SUS440A is typically used for hot-rolled stainless steel plates and strips, while ASTM A959 316H is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
JIS G4304 SUS440A is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A959 316H is defined under ASTM International, originating from United States.
As per chemical composition, JIS G4304 SUS440A vs ASTM A959 316H is a 71.9% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
