Strong Match — 88.9% match
based on chemical composition and mechanical property overlap.
ASTM A959 308 (ASTM A959:2011) and ASTM A959 347 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 308 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while ASTM A959 347 is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
ASTM A959 308 is defined under ASTM International, originating from United States, while ASTM A959 347 is defined under ASTM International, originating from United States.
As per chemical composition, ASTM A959 308 vs ASTM A959 347 is a 88.9% 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 88.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
