201: Cr-Mn stainless metal balls, with properties comparable to AISI 302/304 balls (a bit larger mechanical traits). Balls are offered in the passivated issue.

304: Unhardened austenitc stainless steel balls, they screen excellent mechanical traits, toughness and corrosion resistance. AISI 304L offers lower carbon content, AISI 302 much better mechanical qualities. Balls are presented in the passivated situation.

316: Austenitic stainless metal balls with larger corrosion resistance than AISI 304 balls. They demonstrate great toughness. AISI 316L has a reduce carbon articles (highest ,030%). Balls are presented in the passivated situation.

420C: Martensitic hardened stainless steel balls, they function good hardness, corrosion resistance, wear and abrasion resistance. Balls are supplied in the passivated situation.

440C: Martensitic hardened stainless metal balls, they function outstanding hardness, dress in resistance, area ending, slender dimensional tolerances. For that cause this sort of metal is frequently utilized in precision devices. Balls are provided in the passivated condition.

Corrosion Resistance
201: Equivalent to the corrosion resistance of AISI 302/304 materials.
304: Quite good corrosion resistance with regard to organic substances, oxidating answers, foodstuff, sterilizing remedies. Excellent resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of very hot chloride answers and to tension corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid answers. AISI 302 exhibits somewhat very best corrosion resistance with regard to AISI 304/304L stainless steels.

316: Extremely great corrosion resistance with regard to organic and natural substances, very good resistance to many powerful acids (acetic, phosphoric, sulphuric acid) and on sea drinking water. They are subjected to pitting and crevice corrosion in presence of scorching chloride answers and to anxiety corrosion when temperature exceeds 60°C. They do not resist in contact with hydrochloric and hydrofluoric acids, aqua regia, iron and magnesium chlorides.

420C: Very good corrosion resistance in industrial ambiance, freshwater, steam, alcool, ammonium, several oilfield items and natural and organic compounds, dairy items, delicate acid environments. Fairish in foodstuff and alkaline answers. Reasonable in salt ambiance. It does not resist in speak to with sea h2o and sturdy acids (even if diluted).

440C: The content resists to corrosion in speak to with freshwater, steam, oil, petrol, alcohol. They are subjected to pitting corrosion in sea h2o environments. Bad corrosion resistance in acid environments.

201: Specific bearings, automotive components, switches, die casting devices. They are commonly utilised in the digital industry.

304: Unique bearings and pumps, aerosol pumps, gardening and family sprayers, fragrance miniature pumps, seams, health-related application valves, agricultural backpack sprayers. They are used in foodstuff, aerospace and army sector.

316: Specific bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber, navy, textile market. Apps in photographic products, medical instruments, rapid couplings, recirculating balls, ink cartridges, jewels.

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

440C: Precision bearings, anti-friction bearings, special valves, conveyor belts and rollers, ballpoint pens. They are employed in foodstuff, medical devices, rapid couplings, recirculating ball bearings, knotting products, oil refinery gadgets.
