Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 4367 20NiCrMo2 (IS 4367:1991) and NF A35-565 100C6 are both steel grades.
Both fall under the Alloy Steel category.
IS 4367 20NiCrMo2 is typically used for nickel-chromium-molybdenum case-hardening steel; used for highly stressed gears, shafts, and transmission components requiring high core strength, toughness, and wear-resistant carburized surface, while NF A35-565 100C6 is commonly used for ball bearings, roller bearings, bearing races, rollers, precision tools, wear resistant parts.
IS 4367 20NiCrMo2 is defined under Bureau of Indian Standards (IS), originating from India, while NF A35-565 100C6 is defined under Association Francaise de Normalisation (NF), originating from France.
As per chemical composition, IS 4367 20NiCrMo2 vs NF A35-565 100C6 is a 57.1% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
