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 provides 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 offers higher hardness due to increased carbon content, while 420 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, they 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, they 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, they provide excellent resistance to acids, chlorides and pitting corrosion.
