Minimal Match — 48.3% match
based on chemical composition and mechanical property overlap.
EN ISO 4957 X30WCrV9-3 (EN ISO 4957:2018) and GB/T 1299 3Cr2W8V (GB/T 1299-2014) are both steel grades.
Both fall under the Tool & Die Steels category.
EN ISO 4957 X30WCrV9-3 is typically used for hot extrusion dies, hot forging dies for non-ferrous metals, while GB/T 1299 3Cr2W8V is commonly used for used for hot forging dies, extrusion dies, die-casting molds, hot punches, and hot shear blades..
EN ISO 4957 X30WCrV9-3 is defined under European Standard (EN), originating from Europe, while GB/T 1299 3Cr2W8V is defined under Guobiao Standards (GB/T), originating from China.
As per chemical composition, EN ISO 4957 X30WCrV9-3 vs GB/T 1299 3Cr2W8V is a 72.5% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 48.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
