Close Alternative — 82.3% match
based on chemical composition and mechanical property overlap.
DIN 17210 20CrMo5 (DIN 17210:1986) and KS D3867 SCM415 (KS D 3867:2025) 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 KS D3867 SCM415 is commonly used for gears, shafts, camshafts, piston pins, precision machine components requiring hard surface and tough core..
DIN 17210 20CrMo5 is defined under Deutsches Institut fur Normung (DIN), originating from Germany, while KS D3867 SCM415 is defined under Korean Industrial Standards (KS), originating from South Korea.
As per chemical composition, DIN 17210 20CrMo5 vs KS D3867 SCM415 is a 82.3% 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 82.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
