Related Material — 65% match
based on chemical composition and mechanical property overlap.
EN 10083-1 2C22 (EN 10083-1:1991) and EN 10084 20NiCrMo2-2 (EN 10084:2008) are both steel grades.
EN 10083-1 2C22 is classified under Carbon Steel, while EN 10084 20NiCrMo2-2 is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below.
EN 10083-1 2C22 is typically used for quenched and tempered machine parts; non alloy steels also normalized (clause 1), while EN 10084 20NiCrMo2-2 is commonly used for gears, shafts and automotive transmission components.
EN 10083-1 2C22 is defined under European Standard (EN), originating from Europe, while EN 10084 20NiCrMo2-2 is defined under European Standard (EN), originating from Europe.
As per chemical composition, EN 10083-1 2C22 vs EN 10084 20NiCrMo2-2 is a 67.7% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 65%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
