Strong Match — 98.1% match
based on chemical composition and mechanical property overlap.
IS 4432 20Ni7Mo2 (IS 4432:1988) and SAE J404 4620 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
IS 4432 20Ni7Mo2 is typically used for forgings and fabrication of case-hardened machine or automobile parts, while SAE J404 4620 is commonly used for used for gears, bearings, shafts, transmission parts, pinions, and heavy-duty carburized components..
IS 4432 20Ni7Mo2 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 4620 is defined under SAE International, originating from United States.
As per chemical composition, IS 4432 20Ni7Mo2 vs SAE J404 4620 is a 98.1% 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 98.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
