Strong Match — 92.5% match
based on chemical composition and mechanical property overlap.
JIS G4305 SUSXM7 (JIS G4305:2012) and ASTM A959 347 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4305 SUSXM7 is typically used for cold-rolled stainless steel plates, sheet and strip, while ASTM A959 347 is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
JIS G4305 SUSXM7 is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A959 347 is defined under ASTM International, originating from United States.
As per chemical composition, JIS G4305 SUSXM7 vs ASTM A959 347 is a 92.5% 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 92.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
