Stainless steel balls have similar mechanical properties as chrome steel balls with the advantage of being resistant to corrosive environments. There are several types of stainless steel balls, ranging from the 440C type which offers the greatest hardness and surface finish to the 302 which has extreme toughness and corrosion resistance.
As one of the leading manufacturers of steel balls with 33 years& acute; experience, we are in the position to supply steel balls with good quality and reasonable price.
