Strong Match — 92.9% match
based on chemical composition and mechanical property overlap.
IS 4367 20NiCrMo2 (IS 4367:1991) and SAE J404 8622 (SAE J404:2009) 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 SAE J404 8622 is commonly used for chemistry-only alloy steel grade; see the composition notes for product scope.
IS 4367 20NiCrMo2 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 8622 is defined under SAE International, originating from United States.
As per chemical composition, IS 4367 20NiCrMo2 vs SAE J404 8622 is a 92.9% 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 92.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
