Size 1.588mm to 6.35mm Precision 440 Stainless Steel Balls for Auto
440 stainless steel balls offer the precise geometry and fine
surface finish that makes them especially useful for bicycles,
casters, drawer slides, door locks and many other applications with
the added benefit of corrosion resistance. 440 stainless steel is a
high carbon martensitic stainless steel which has high strength,
good hardness and wear resistance. This type of stainless is
capable of attaining, after heat treatment, the highest strength,
hardness and wear resistance of all the stainless alloys. Unlike
some stainless steel, this 400 series metal has a composition which
allows it to be attracted to a magnet.microstructure for each
stainless steel ball. Throughout the manufacturing process,
statistical process control assures tolerance accuracy, fine
surface finish and consistent high quality. Chrome steel balls
offer the precise geometry and fine surface finish that makes them
especially useful for bicycles, casters, drawer slides, door locks
and many other applications.
