good quality AISI420 stainless steel balls

Hardened Stainless Steel
AISI 440C stainless steel balls afford the advantage of maximum hardness combined with corrosion-

resisting properties. This hardness, together with precise geometry and fine surface finish, makes them

especially useful for both bearing and valve applications in petroleum refineries and other severe

environmental applications. 
Consumable electrode vacuum melted (CEVM) and vacuum induction melted/vacuum arc remelted

(VIM-VAR) material is available upon request. All sizes and grades of corrosion-resisting hardened

stainless steel balls are passivated.

Hardened Stainless Steel 
AISI type 420 stainless steel balls have fair-to-good corrosion resistance and good material strength.

They resist corrosion from alcohol, ammonia, food environments, fresh water, many petroleum products

and organic materials and some mild acid environments. They are found in bearings, valves, lighters and

writing instruments.

Material Analysis:

C= max 0.15%, Cr=17 - 19%, Mn=max 2.0%, Si=max 1.00%, S= max0.03%, P=max 0.045%,

Ni=8-10%

Unhardened Stainless Steel
AISI type 304 stainless steel balls meet requirements for an unhardened ball with excellent toughness

and resistance to corrosion. Corrosion resistance may be increased through annealing. Both non-annealed

and annealed balls are widely used in valves and related equipment. 
Stainless type 304 balls are capable of resisting corrosion by such agents as oxidizing solutions, most

organic chemicals, food stuffs and sterilizing solutions. They are moderately resistant to sulfuric acids.

Non-magnetic properties available upon request. Applications include aerosol, sprayers, finger pump

mechanisms, milk machine blenders, food processing equipment and medical applications.
