302 Stainless Steel balls provides extreme toughness and corrosion resistance from oxidizing solutions and many organic compounds in an unhardened state. In its annealed condition it withstands attacks by foodstuffs, dyes, sterilizing solutions and nitric acid. Not recommended for sulfuric or halogen applications. 302 is slightly magnetic.

304 Stainless Steel balls are an austentistic, unhardened stainless steel with excellent resistance to corrosion by oxidizing agents, most organic chemicals, food stuffs and sterilizing solutions. 304 Stainless Steel has a lower carbon content than 302 Stainless Steel. 304 is slightly magnetic. Ask us about our special packaging for surface protection.

316 stainless steel balls  provide resistance to sulfurous acid compounds and other highly corrosive environments. 316 Stainless Steel is used in the presence of sulfuric, phosphoric, and acetic acids. 316 is the least magnetic of the 300 series. Ask us about our special packaging for surface protection.  

AISI type 316L stainless steel balls has a lower carbon content than 316 stainless, which gives it even higher corrosion resistance than the excellent resistance of type 316. Both types offer excellent resistance to sulphuric acid compounds. Applications for type 316L balls include Jewelry and medical uses.

420 Stainless Steel balls offer good hardness and surface finish. It is generally used for all applications requiring resistance to corrosion from water, steam, air and gasoline. 420 is not recommended for applications requiring resistance to most chemical solutions. 420 is also magnetic. We are one of the few suppliers of 420 in millimeters.

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. 440 is also magnetic.
