Strong Match — 100% match
based on chemical composition and mechanical property overlap.
JIS G4304 SUS316 (JIS G4304:2021) and ASTM A959 SS316 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4304 SUS316 is typically used for hot-rolled stainless steel plates and strips, while ASTM A959 SS316 is commonly used for marine, chemical, pharmaceutical, food processing equipment.
JIS G4304 SUS316 is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A959 SS316 is defined under ASTM International, originating from United States.
As per chemical composition, JIS G4304 SUS316 vs ASTM A959 SS316 is a 100% 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 100%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
