Unhardened austenitc stainless steel balls, they display good mechanical characteristics, toughness and corrosion resistance. AISI 304L provides lower carbon content, AISI 302 better mechanical characteristics. Balls are provided in the passivated condition.
Special bearings and pumps, aerosol pumps, gardening and household sprayers, perfume miniature pumps, seams, medical application valves, agricultural backpack sprayers. They are used in foodstuff, aerospace and military industry.
