Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
GB/T 18254 GCr15 (GB/T 18254-2016) and GB/T 1299 3Cr2W8V (GB/T 1299-2014) are both steel grades.
Both fall under the Tool & Die Steels category.
GB/T 18254 GCr15 is typically used for ball bearings, roller bearings, bearing races, 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..
GB/T 18254 GCr15 is defined under Guobiao Standards (GB/T), originating from China, while GB/T 1299 3Cr2W8V is defined under Guobiao Standards (GB/T), originating from China.
As per chemical composition, GB/T 18254 GCr15 vs GB/T 1299 3Cr2W8V is a 64.1% 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.
