304 stainless steel balls:
Very good corrosion resistance with respect to organic substances, oxidating solutions, foodstuff, sterilizing solutions. Good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of hot chloride solutions and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions.
316 stainless steel balls:
Very good corrosion resistance with respect to organic substances, good resistance to several strong acids (acetic, phosphoric, sulphuric acid) and on sea water. They are subjected to pitting and crevice corrosion in presence of hot chloride solutions and to stress corrosion when temperature exceeds 60°C. They do not resist in contact with hydrochloric and hydrofluoric acids, aqua regia, iron and magnesium chlorides.
420C stainless steel balls:
Good corrosion resistance in industrial atmosphere, freshwater, steam, alcool, ammonium, several oilfield products and organic compounds, dairy products, mild acid environments. Fairish in foodstuff and alkaline solutions. Fair in salt atmosphere. It does not resist in contact with sea water and strong acids (even if diluted).
440C stainless steel balls:
The material resists to corrosion in contact with freshwater, steam, oil, petrol, alcohol. They are subjected to pitting corrosion in sea water environments. Poor corrosion resistance in acid environments.
