Description
Stainless Steel Ball for Ball Bearing
9Cr18（440） is a high carbon chromium martensitic stainless bearing steel. After quenching, it has high hardness and wear resistance, and high temperature and low temperature dimensional stability.
9Cr18（440） stainless steel balls are suitable for the manufacture of bearings in seawater, river water, nitric acid, steam and marine and other corrosive media, such as bearings in ships, submersible pump components, bearings in petroleum and chemical machinery, marine instrument bearings, etc.
