AISI440 stainless steel balls are deep freeze stabilized after heat treatment. AISI440 balls are applicated in bearings, valves, locking mechanisms, fasteners, quick-disconnect couplings, etc. AISI440 Stainless Steel balls are martensitic type stainless steel that is used extensively in steel ball bearing applications that require hardness, dimensional stability, corrosion resistance, and toughness.

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.AISI440 balls are uses in bearings, valves, locking mechanisms, fasteners and quick-disconnect couplings etc.
