Strong Match — 90.7% match
based on chemical composition and mechanical property overlap.
ASTM A240/A240M S31753 (ASTM A240/A240M:2025) and JIS G4304 SUS317LN (JIS G4304:2021) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A240/A240M S31753 is typically used for pressure vessels and general applications (plate, sheet and strip), while JIS G4304 SUS317LN is commonly used for hot-rolled stainless steel plates and strips.
ASTM A240/A240M S31753 is defined under ASTM International, originating from United States, while JIS G4304 SUS317LN is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, ASTM A240/A240M S31753 vs JIS G4304 SUS317LN is a 98.6% match.
As per mechanical properties, the match is 75%.
Combined, this makes them a strong match overall at 90.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
