Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
NF A35-574 Z7CN18-09 (NF A35-574:1990) and ASTM A959 .- (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
NF A35-574 Z7CN18-09 is typically used for used for food processing equipment, kitchen equipment, chemical tanks, piping, architectural components, and fasteners., while ASTM A959 .- is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
NF A35-574 Z7CN18-09 is defined under Association Francaise de Normalisation (NF), originating from France, while ASTM A959 .- is defined under ASTM International, originating from United States.
As per chemical composition, NF A35-574 Z7CN18-09 vs ASTM A959 .- is a 70% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
