Strong Match — 86.6% match
based on chemical composition and mechanical property overlap.
GB/T 3077 20CrMnTi (GB/T 3077:2015) and EN 10084 20MnCrS5 (EN 10084:2008) are both steel grades.
Both fall under the Alloy Steel category.
GB/T 3077 20CrMnTi is typically used for gears, transmission shafts, pinions, carburized components, automotive parts, while EN 10084 20MnCrS5 is commonly used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1).
GB/T 3077 20CrMnTi is defined under Guobiao Standards (GB/T), originating from China, while EN 10084 20MnCrS5 is defined under European Standard (EN), originating from Europe.
As per chemical composition, GB/T 3077 20CrMnTi vs EN 10084 20MnCrS5 is a 79.9% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 86.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
