Frequently Asked Questions
What makes GCr15 superior to standard carbon steel for precision balls?
GCr15’s chromium content (1.3-1.6%) creates finer carbides in the microstructure, resulting in better wear resistance and fatigue life compared to standard carbon steels.
How does G10 tolerance compare to other grades?
G10 is among the tightest standard tolerance grades, with only G5 being more precise. G10 offers the optimal balance of precision and cost-effectiveness for most industrial applications.
What surface treatments are available?
Standard balls have a polished finish, but we can apply specialized coatings including chromium plating, nickel plating, or Teflon® coatings for specific applications.
What packaging options are available?
We offer bulk packaging, plastic tubes, or custom packaging with nitrogen purging for oxidation-sensitive applications.
What is the typical lead time for orders?
Standard sizes ship within 5-7 business days. Custom sizes and coatings may require 2-3 weeks depending on specifications.
