Close Alternative — 74.9% match
based on chemical composition and mechanical property overlap.
ASTM A959 440C (ASTM A959:2011) and IS 1570 (Part 5) X85Cr18Mo2V (IS 1570 (Part 5):1985) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 440C is defined under ASTM International, originating from United States, while IS 1570 (Part 5) X85Cr18Mo2V is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A959 440C vs IS 1570 (Part 5) X85Cr18Mo2V is a 74.9% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 74.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
