Strong Match — 97.2% match
based on chemical composition and mechanical property overlap.
ASTM A959 301 (ASTM A959:2011) and JIS G4305 SUS301 (JIS G4305:2012) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 301 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while JIS G4305 SUS301 is commonly used for cold-rolled stainless steel plates, sheet and strip.
ASTM A959 301 is defined under ASTM International, originating from United States, while JIS G4305 SUS301 is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, ASTM A959 301 vs JIS G4305 SUS301 is a 97.2% 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 97.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
