Related Material — 58.6% match
based on chemical composition and mechanical property overlap.
NF A35-552 34NCD6 (NF A35-552:1986) and IS 1570 (Part 4) 07Cr4Mo6 (IS 1570 (Part 4):1988) are both steel grades.
Both fall under the Alloy Steel category.
NF A35-552 34NCD6 is defined under Association Francaise de Normalisation (NF), originating from France, while IS 1570 (Part 4) 07Cr4Mo6 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, NF A35-552 34NCD6 vs IS 1570 (Part 4) 07Cr4Mo6 is a 58.6% 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 58.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
