General Information
Balls made from AISI 420 stainless steel have a lower chrome content compared to 440C, making them suitable for applications where high corrosion resistance is not critical. They offer moderate resistance to environments such as fresh water, steam, oil, gasoline, blood, perspiration, alcohol, and food. However, they do not pass the 40-hour salt spray test.

International Equivalents
The material is equivalent to AISI 420, JIS SUS 420, JI X20 CR13, Z40 C13, EN56D, and Wks 1.4034.
