Strong Match — 100% match
based on chemical composition and mechanical property overlap.
ASTM A276/A276M S30215 (ASTM A276/A276M:2017) and ASTM A959 302B (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A276/A276M S30215 is typically used for stainless steel bars and shapes (hot-finished or cold-finished), while ASTM A959 302B is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
ASTM A276/A276M S30215 is defined under ASTM International, originating from United States, while ASTM A959 302B is defined under ASTM International, originating from United States.
As per chemical composition, ASTM A276/A276M S30215 vs ASTM A959 302B is a 100% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 100%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
