Close Alternative — 82.1% match
based on chemical composition and mechanical property overlap.
DIN 17210 20CrMo5 (DIN 17210:1986) and SAE J404 4120 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
DIN 17210 20CrMo5 is typically used for used in gears, shafts, pinions, camshafts, and transmission components., while SAE J404 4120 is commonly used for used for gears, crankshafts, studs, pins, machinery parts, and transmission components..
DIN 17210 20CrMo5 is defined under Deutsches Institut fur Normung (DIN), originating from Germany, while SAE J404 4120 is defined under SAE International, originating from United States.
As per chemical composition, DIN 17210 20CrMo5 vs SAE J404 4120 is a 82.1% 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 82.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
