Close Alternative — 75.9% match
based on chemical composition and mechanical property overlap.
NF A35-565 16NC11 and IS 1570 (Part 4) 15Cr6Ni6 (IS 1570 (Part 4):1988) are both steel grades.
Both fall under the Alloy Steel category.
NF A35-565 16NC11 is defined under Association Francaise de Normalisation (NF), originating from France, while IS 1570 (Part 4) 15Cr6Ni6 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, NF A35-565 16NC11 vs IS 1570 (Part 4) 15Cr6Ni6 is a 75.9% 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 75.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
