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

304: Unhardened austenitc stainless steel balls, they show very good mechanical traits, toughness and corrosion resistance. AISI 304L offers decrease carbon material, AISI 302 far better mechanical characteristics. Balls are offered in the passivated situation.

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

420C: Martensitic hardened stainless steel balls, they characteristic good hardness, corrosion resistance, put on and abrasion resistance. Balls are supplied in the passivated condition.

440C: Martensitic hardened stainless steel balls, they function impressive hardness, dress in resistance, area ending, slim dimensional tolerances. For that explanation this sort of steel is regularly employed in precision products. Balls are provided in the passivated situation.

Corrosion Resistance
201: Equivalent to the corrosion resistance of AISI 302/304 components.
304: Quite very good corrosion resistance with respect to organic and natural substances, oxidating answers, foodstuff, sterilizing remedies. Good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of scorching chloride solutions and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 exhibits slightly greatest corrosion resistance with respect to AISI 304/304L stainless steels.

316: Really great corrosion resistance with regard to organic substances, good resistance to many sturdy acids (acetic, phosphoric, sulphuric acid) and on sea drinking water. They are subjected to pitting and crevice corrosion in existence of very hot chloride remedies and to stress corrosion when temperature exceeds 60°C. They do not resist in speak to 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 products and organic and natural compounds, dairy merchandise, gentle acid environments. Fairish in foodstuff and alkaline options. Reasonable in salt ambiance. It does not resist in make contact with with sea h2o and powerful acids (even if diluted).

440C: The substance resists to corrosion in get in touch with with freshwater, steam, oil, petrol, alcoholic beverages. They are subjected to pitting corrosion in sea drinking water environments. Bad corrosion resistance in acid environments.

Application
201: Unique bearings, automotive parts, switches, die casting gadgets. They are widely employed in the electronic sector.

304: Particular bearings and pumps, aerosol pumps, gardening and home sprayers, fragrance miniature pumps, seams, medical software valves, agricultural backpack sprayers. They are utilized in foodstuff, aerospace and army sector.

316: Special bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber, army, textile business. Apps in photographic products, health care devices, swift couplings, recirculating balls, ink cartridges, jewels.

420C: Particular bearings, anti-friction bearings, unique pumps, recirculating balls, lighters, pens, automotive seatbelts & elements.

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