Strong Match — 90.2% match
based on chemical composition and mechanical property overlap.
JIS G4304 SUS312L (JIS G4304:2021) and ASTM A276/A276M S31254 (ASTM A276/A276M:2017) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4304 SUS312L is typically used for hot-rolled stainless steel plates and strips, while ASTM A276/A276M S31254 is commonly used for stainless steel bars and shapes (hot-finished or cold-finished).
JIS G4304 SUS312L is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A276/A276M S31254 is defined under ASTM International, originating from United States.
As per chemical composition, JIS G4304 SUS312L vs ASTM A276/A276M S31254 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.
