Strong Match — 88.9% match
based on chemical composition and mechanical property overlap.
JIS G4305 SUS316N (JIS G4305:2012) and ASTM A240/A240M S31651 (ASTM A240/A240M:2025) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4305 SUS316N is typically used for cold-rolled stainless steel plates, sheet and strip, while ASTM A240/A240M S31651 is commonly used for pressure vessels and general applications (plate, sheet and strip).
JIS G4305 SUS316N is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A240/A240M S31651 is defined under ASTM International, originating from United States.
As per chemical composition, JIS G4305 SUS316N vs ASTM A240/A240M S31651 is a 95.8% match.
As per mechanical properties, the match is 75%.
Combined, this makes them a strong match overall at 88.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
