Stainless Steel Balls AISI 440C offer maximum uniform hardness and good corrosion resistance, 440c stainless steel balls are used in bearings, valves, locking mechanisms, fasteners and quick-disconnect couplings etc. AISI440C stainless steel balls offer the maximum material strength and good corrosion resistance. They afford the advantage of maximum hardness combined with corrosion-resisting properties. This hardness, together with precise geometry and fine surface finish, makes them especially useful for bearings, valves, locking mechanisms, fasteners and quick-disconnect couplings, petroleum industry, bearing assemblies, check valves, and other applications where corrosion resistance and maximum hardness is critical.

Application Of Stainless Steel Balls
AISI304, 304L, 316, 316L
strong anti-rust performance, can be in direct contact with neutral liquids. Special bearings, water pumps, valves, aerosols, dispensers, food machinery, medical, cosmetics and other fields.
AISI420, 420C, 440, 440C
precision bearings, auto parts, bicycles, mixers, slide rails, conveyor belts, skateboards, casters, valves, etc.
This material is ferro-magnetic and makes a fair permanent.Mental balls are deep freeze stabilised after heat treatment.AISI440C balls are uses in bearings, valves, locking mechanisms, fasteners and quick-disconnect couplings etc.
