Strong Match — 90.2% match
based on chemical composition and mechanical property overlap.
ASTM A276/A276M S31254 (ASTM A276/A276M:2017) and JIS G4304 SUS312L (JIS G4304:2021) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A276/A276M S31254 is typically used for stainless steel bars and shapes (hot-finished or cold-finished), while JIS G4304 SUS312L is commonly used for hot-rolled stainless steel plates and strips.
ASTM A276/A276M S31254 is defined under ASTM International, originating from United States, while JIS G4304 SUS312L is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, ASTM A276/A276M S31254 vs JIS G4304 SUS312L is a 85.3% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 90.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
