Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
ASTM A959 440F (ASTM A959:2011) and IS 11169 (Part 2) X12Cr12 (IS 11169 (Part 2):1989) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 440F is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while IS 11169 (Part 2) X12Cr12 is commonly used for cold heading and cold extrusion; the standard covers wires, wire rods and bars (clause 1.1).
ASTM A959 440F is defined under ASTM International, originating from United States, while IS 11169 (Part 2) X12Cr12 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A959 440F vs IS 11169 (Part 2) X12Cr12 is a 78.8% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
