Close Alternative — 71.3% match
based on chemical composition and mechanical property overlap.
DIN 17200 40NiCrMo6 (DIN 17200:1986) and GOST 4543 40HNMA (GOST 4543-2016) are both steel grades.
Both fall under the Alloy Steel category.
DIN 17200 40NiCrMo6 is typically used for heavy forgings, crankshafts, high strength components, while GOST 4543 40HNMA is commonly used for used for gears, shafts, spindles, connecting rods, and aerospace parts..
DIN 17200 40NiCrMo6 is defined under Deutsches Institut fur Normung (DIN) (Germany).
As per chemical composition, DIN 17200 40NiCrMo6 vs GOST 4543 40HNMA is a 90.2% match.
As per mechanical properties, the match is 33.3%.
Combined, this makes them a close alternative overall at 71.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
