Function
201: Cr-Mn stainless steel balls, with qualities related to AISI 302/304 balls (marginally higher mechanical qualities). Balls are provided in the passivated issue.

304: Unhardened austenitc stainless steel balls, they display very good mechanical characteristics, toughness and corrosion resistance. AISI 304L gives lower carbon material, AISI 302 much better mechanical traits. Balls are offered in the passivated condition.

316: Austenitic stainless steel balls with increased corrosion resistance than AISI 304 balls. They present very good toughness. AISI 316L has a lower carbon articles (highest ,030%). Balls are presented in the passivated issue.

420C: Martensitic hardened stainless metal balls, they function very good hardness, corrosion resistance, put on and abrasion resistance. Balls are offered in the passivated situation.

440C: Martensitic hardened stainless steel balls, they function impressive hardness, wear resistance, surface finishing, slim dimensional tolerances. For that purpose this type of metal is often utilised in precision gadgets. Balls are presented in the passivated issue.

Corrosion Resistance
201: Similar to the corrosion resistance of AISI 302/304 materials.
304: Quite excellent corrosion resistance with regard to natural and organic substances, oxidating solutions, foodstuff, sterilizing options. Good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of scorching chloride answers and to anxiety corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid answers. AISI 302 displays slightly very best corrosion resistance with regard to AISI 304/304L stainless steels.

316: Really excellent corrosion resistance with respect to organic and natural substances, excellent resistance to many strong acids (acetic, phosphoric, sulphuric acid) and on sea water. They are subjected to pitting and crevice corrosion in existence of hot chloride remedies and to pressure corrosion when temperature exceeds 60°C. They do not resist in make contact with with hydrochloric and hydrofluoric acids, aqua regia, iron and magnesium chlorides.

420C: Very good corrosion resistance in industrial atmosphere, freshwater, steam, alcool, ammonium, a number of oilfield merchandise and organic compounds, dairy products, delicate acid environments. Fairish in foodstuff and alkaline answers. Reasonable in salt environment. It does not resist in contact with sea water and sturdy acids (even if diluted).

440C: The materials resists to corrosion in make contact with with freshwater, steam, oil, petrol, alcoholic beverages. They are subjected to pitting corrosion in sea water environments. Very poor corrosion resistance in acid environments.

Software
201: Specific bearings, automotive factors, switches, die casting products. They are commonly employed in the electronic business.

304: Particular bearings and pumps, aerosol pumps, gardening and family sprayers, fragrance miniature pumps, seams, health-related software valves, agricultural backpack sprayers. They are utilised in foodstuff, aerospace and armed forces sector.

316: Special bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber, armed forces, textile sector. Apps in photographic devices, health care devices, rapid couplings, recirculating balls, ink cartridges, jewels.

420C: Specific bearings, anti-friction bearings, particular pumps, recirculating balls, lighters, pens, automotive seatbelts & components.

440C: Precision bearings, anti-friction bearings, special valves, conveyor belts and rollers, ballpoint pens. They are utilised in foodstuff, health-related devices, swift couplings, recirculating ball bearings, knotting devices, oil refinery gadgets.
