Stainless steel ball is used in various fields, our factory can produce many types of stainless steel balls including 400 series martensitic stainless steel (we have patent degaussing technology) and 300 series austenitic stainless steel，and for martensitic steel balls, the heat treatment process of martensitic steel balls is complex, and high precision requirements. Martensitic steel ball can be used in aviation, aerospace, bearings, motors, high precision instruments, valves and oil due to the perfect corrosion resistance, wear resistance toughness and hardness. We also have normal stainless steel ball for daily necessities and crafts.
