AISI 440C Stainless Steel Ball

Stainless Steel AISI 440C

General Information
These balls give maximum hardness with good corrosion resistance to fresh water, steam, crude oil, gasoline, alcohol, food environment, blood and perspiration. In addition this material is ferro-magnetic and makes a fair permanent magnet. Balls are deep freeze stabilized after heat treatment.
