304 Stainless steel ball 

 

AISI 304 steel balls have no good hardness but offer good corrosion resistance,

 

they offer good resistance to atomospheric corrosion, dyes, food processing, valves, sex products and so on.

 

Hardness :HRC25-39

 

316 Stainless steel ball

 

AISI 316 steel balls have no good hardness, but have better corrosion resistance than

 

AISI 304, AISI 316 stainless steel balls offer good corrosion resistance to sulphuric acid compounds.

 

They are used in nail polish, trigger sprayers, dispenser valves, body jewelry and so on.

 

Hardness :HRC25-39

 

420 Stainless steel ball

 

AISI 420 have good hardness and fair-to-good corrosion resistance and strength,

 

it is generally used for all applications requiring resistance to corrosion such as bearings, valves,

 

writting instruments, food environment, fresh water, many petroleum products and mild acid environments.

 

AISI 420 is also magnetic.

 

Hardness :HRC52-65

 

 

 440 Stainless Steel Ball

 
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.
