AISI 440 and 440C stainless steel balls are high-carbon martensitic stainless steels that can be hardened to achieve excellent wear resistance and high load capacity. 440C stainless steel balls provide higher hardness and is widely used in precision bearing and high-performance applications.

AISI 420 and 420C stainless steel balls are martensitic stainless steels that can be hardened to achieve high strength and wear resistance. 420C stainless steel ball offers higher hardness due to increased carbon content, while 420 stainless steel ball provides relatively better corrosion resistance and toughness.

AISI 316 stainless steel balls provide enhanced corrosion resistance compared to 304, particularly in chloride-containing and saltwater-exposure environments. With added molybdenum, 316 stainless steel balls are suitable for chemical processing and corrosion-sensitive applications requiring long-term reliability.

AISI 304 stainless steel balls provide reliable corrosion resistance in humid and mildly corrosive environments. With stable austenitic structure and consistent performance, 304 stainless steel balls are widely used in industrial applications requiring durability and cleanliness.

904L stainless steel balls are high-alloy austenitic stainless steel balls designed for highly corrosive environments. With high nickel, molybdenum and copper content, 904l stainless steel balls provide excellent resistance to acids, chlorides and pitting corrosion.
