Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
GOST 5950 3H2W8F (GOST 5950-2000) and EN ISO 683-17 100Cr6 (EN ISO 683-17:2014) are both steel grades.
Both fall under the Tool & Die Steels category.
GOST 5950 3H2W8F is typically used for used for forging dies, extrusion tools, hot punches, mandrels, and die inserts., while EN ISO 683-17 100Cr6 is commonly used for rolling element bearings, precision components, cold work tooling.
EN ISO 683-17 100Cr6 is defined under European Standard (EN) (Europe).
As per chemical composition, GOST 5950 3H2W8F vs EN ISO 683-17 100Cr6 is a 61.8% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
