Strong Match — 88% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 2) X12Cr12 (IS 11169 (Part 2):1989) and ASTM A959 420 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
IS 11169 (Part 2) X12Cr12 is typically used for cold heading and cold extrusion; the standard covers wires, wire rods and bars (clause 1.1), while ASTM A959 420 is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
IS 11169 (Part 2) X12Cr12 is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 420 is defined under ASTM International, originating from United States.
As per chemical composition, IS 11169 (Part 2) X12Cr12 vs ASTM A959 420 is a 88% 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%.
Frequently Compared With IS 11169 (Part 2) X12Cr12:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
