SUS440C Grinding Stainless Steel Balls G1000 Grade 7/8 Inch 5/8 Inch

SUS440C Grinding Stainless Steel Balls G1000 Grade 7/8 Inch 5/8 Inch

440 Stainless Steel balls are a martenistic-type stainless steel which is used extensively in

steel ball bearing applications that require hardness, dimensional stability, corrosion resistance and toughness.

440 Stainless Steel is also used for corrosion-resistant ball and check valves.

440 ball are resistant to corrosion from fresh water, steam, crude oil, gasoline, perspiration,

alcohol, blood and food stuffs. Maximum resistance to corrosion and tarnishing is only achieved

when 440 is fully hardened and surfaces are polished to a high luster.
