Austenitic stainless steel balls are a type of ball bearings made from austenitic stainless steel, which is a high-performance alloy known for its excellent corrosion resistance and strength. These balls are commonly used in applications where the bearing is exposed to corrosive environments, such as in food processing machinery, chemical plants, marine equipment, medical equipment, and other demanding industrial applications. They are also used in precision instruments, valves, locks, and other applications where high strength and corrosion resistance are required. Austenitic stainless steel balls are typically available in a range of sizes and grades to meet specific application requirements.
