Unhardened austenitic stainless steel balls, they display good mechanical characteristics, toughness and corrosion resistance. They are capable of resisting corrosion by such agents as oxidizing solutions, most organic chemicals, food stuffs and sterilizing solutions, 304 shows weak attraction to magnetism and is nonmagnetic only when annealed.
Applications widely include special bearings and pumps, aerosol pumps, perfume miniature pumps, milk machine blenders, food processing equipment, gardening and household sprayers, seams, medical application valves, agricultural backpack sprayers.
Balls are environmentally friendly non-toxic. Please be rest assured to use!
(SUS304&SUS304L&SUS316&SUS316L&SUS440C&SUS420C)
Corrosion-resistant steel balls are mainly used for valves, which are used in a corrosive environment. We offer two types of stainless steel balls; martensitic (SUS400) and austenitic (SUS300). In particular, steel balls made of SUS440 have strength and accuracy comparable to those from SUJ2, as well as excellent corrosion resistance, so they are also used for bearings which require corrosion resistance.
