Description
Stainless Steel Ball for Roller Screw
The characteristics and uses of 9Cr18Mo (440C) are basically the same as those of 9Cr18 (440) steel, but it has higher hardness and tempering resistance after quenching. Molybdenum can increase the passivation effect of stainless steel.
9Cr18Mo（440C） 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.
