440C stainless steel ball

AISI 440-C stainless steel balls are made of magnetic material and have a higher through hardness than other stainless steel balls. AISI 440-C stainless steel balls are considerably resistant to corrosion from water, steam, oil, gasoline, and alcohol. These metal balls are passivated. The high hardness, high grade of surface finish, and extremely accurate tolerances of AISI 440-C stainless steel ensure that this alloy is an excellent choice for stainless steel precision ball bearings, oil refinery valves, ball point pen balls, and other rigid environmental applications.

440C Stainless Steel Balls Material Analysis

AISI Type 440C balls are a martenistic-type stainless steel, which is used extensively in bearing applications that require corrosion-resisting properties. 440C balls are resistant to corrosion from fresh water, steam, crude oil, gasoline, perspiration, alcohol, blood and foodstuffs. Maximum resistance to corrosion and tarnishing is only achieved when 440C is fully hardened and surfaces are polished to a high luster. TRD provides 440C balls in vacuum melt condition upon request. Sizes are available in millimeters, inches and fractions.
