Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
GB/T 1299 4Cr5MoSiV (GB/T 1299-2014) and EN ISO 4957 1.2316 (EN ISO 4957:2018) are both steel grades.
Both fall under the Tool & Die Steels category.
GB/T 1299 4Cr5MoSiV is typically used for die casting dies, extrusion tooling, while EN ISO 4957 1.2316 is commonly used for plastic injection moulds for corrosive materials, food packaging moulds.
GB/T 1299 4Cr5MoSiV is defined under Guobiao Standards (GB/T), originating from China, while EN ISO 4957 1.2316 is defined under European Standard (EN), originating from Europe.
As per chemical composition, GB/T 1299 4Cr5MoSiV vs EN ISO 4957 1.2316 is a 53.4% 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.
