Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10084 17CrNi6-6 (EN 10084:2008) and EN 10028-2 10CrMo9-10 (EN 10028-2:2017) are both steel grades.
Both fall under the Alloy Steel category.
EN 10084 17CrNi6-6 is typically used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1), while EN 10028-2 10CrMo9-10 is commonly used for flat products for pressure purposes.
EN 10084 17CrNi6-6 is defined under European Standard (EN), originating from Europe, while EN 10028-2 10CrMo9-10 is defined under European Standard (EN), originating from Europe.
As per chemical composition, EN 10084 17CrNi6-6 vs EN 10028-2 10CrMo9-10 is a 55.1% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
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.
