Strong Match — 97.3% match
based on chemical composition and mechanical property overlap.
AISI 52100 and GB/T 18254 GCr15 (GB/T 18254-2016) are both steel grades.
Both fall under the Tool & Die Steels category.
AISI 52100 is typically used for anti-friction bearings, ball screws, precision rollers, while GB/T 18254 GCr15 is commonly used for ball bearings, roller bearings, bearing races.
AISI 52100 is defined under AISI, originating from United States, while GB/T 18254 GCr15 is defined under Guobiao Standards (GB/T), originating from China.
As per chemical composition, AISI 52100 vs GB/T 18254 GCr15 is a 95.9% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 97.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
Can AISI 52100 Be Substituted With GB/T 18254 GCr15?
AISI 52100 and GB/T 18254 GCr15 overlap closely enough on chemistry and mechanical properties that GB/T 18254 GCr15 is often considered as a substitute for AISI 52100 in many applications. Always confirm the specific property range your application needs before substituting, and check with your supplier's mill certificate.
