Strong Match — 87% match
based on chemical composition and mechanical property overlap.
JIS G4305 SUS302B (JIS G4305:2012) and ASTM A276/A276M S30215 (ASTM A276/A276M:2017) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4305 SUS302B is typically used for cold-rolled stainless steel plates, sheet and strip, while ASTM A276/A276M S30215 is commonly used for stainless steel bars and shapes (hot-finished or cold-finished).
JIS G4305 SUS302B is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A276/A276M S30215 is defined under ASTM International, originating from United States.
As per chemical composition, JIS G4305 SUS302B vs ASTM A276/A276M S30215 is a 97.2% match.
As per mechanical properties, the match is 66.7%.
Combined, this makes them a strong match overall at 87%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
