Strong Match — 95.3% match
based on chemical composition and mechanical property overlap.
JIS G4304 SUS301L (JIS G4304:2021) and ASTM A959 301LN (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4304 SUS301L is typically used for hot-rolled stainless steel plates and strips, while ASTM A959 301LN is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
JIS G4304 SUS301L is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A959 301LN is defined under ASTM International, originating from United States.
As per chemical composition, JIS G4304 SUS301L vs ASTM A959 301LN is a 95.3% 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 95.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
