Minimal Match — 51.7% match
based on chemical composition and mechanical property overlap.
GB/T 1222 55CrMnA (GB/T 1222-2016) and EN 10089 50CrV4 (EN 10089:2002) are both steel grades.
Both fall under the Spring Steel category.
GB/T 1222 55CrMnA is typically used for automotive leaf springs, coil springs, while EN 10089 50CrV4 is commonly used for valve springs, high duty coil springs, hand tools.
GB/T 1222 55CrMnA is defined under Guobiao Standards (GB/T), originating from China, while EN 10089 50CrV4 is defined under European Standard (EN), originating from Europe.
As per chemical composition, GB/T 1222 55CrMnA vs EN 10089 50CrV4 is a 77.6% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 51.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
