Close Alternative — 84.9% match
based on chemical composition and mechanical property overlap.
IS 4432 20Mn5Cr5 (IS 4432:1988) and SAE J404 5120 (SAE J404:2000) are both steel grades.
Both fall under the Alloy Steel category.
IS 4432 20Mn5Cr5 is typically used for forgings and fabrication of case-hardened machine or automobile parts, while SAE J404 5120 is commonly used for chemistry-only alloy steel grade; see the composition notes for product scope.
IS 4432 20Mn5Cr5 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 5120 is defined under SAE International, originating from United States.
As per chemical composition, IS 4432 20Mn5Cr5 vs SAE J404 5120 is a 84.9% 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 84.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
