Stainless Steel Ball AISI 420

General Information

Balls of this material have a lower chrome content than 440C, and are used in application where the more rigid corrosion resistance requirements can be relaxed. They have fair resistance to fresh water, steam, oil gasoline, blood, perspiration, alcohol and food environment. However will not pass 40 hours salt spray test.
