Strong Match — 95% match
based on chemical composition and mechanical property overlap.
ASTM A959 316L (ASTM A959:2011) and JIS G4304 SUS316L (JIS G4304:2021) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 316L is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while JIS G4304 SUS316L is commonly used for hot-rolled stainless steel plates and strips.
ASTM A959 316L is defined under ASTM International, originating from United States, while JIS G4304 SUS316L is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, ASTM A959 316L vs JIS G4304 SUS316L is a 95% 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 95%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
