AISI 302/304/304L Stainless Steel Balls

AISI 302 / 304 / 304L Stainless Steel Balls

The Steel balls are unhardened and austenitc in nature. These Steel balls have good mechanical properties and are high performing in the corrosion resistance factor. As per a basic principle all stainless steel balls are passivated. These balls can be offered in two different types, Magnetic balls & Non Magnetic Balls depending on the end application of the balls.

Applications: Aerosol pumps (medical/pharmaceutical industries), grinding media, food industry, bearings, agricultural industry and Automotive industry.

Corrosion resistance: balls can be offered with a basic 24 hour/ 48 hour / 72 hour salt spray testing as well as these Steel balls can withstand the vigorous L'oreal testing, which shows the high resistance against corrosion.
