Function
201: Cr-Mn stainless metal balls, with qualities equivalent to AISI 302/304 balls (a bit larger mechanical qualities). Balls are presented in the passivated situation.
304: Unhardened austenitc stainless steel balls, they exhibit excellent mechanical attributes, toughness and corrosion resistance. AISI 304L supplies decrease carbon content, AISI 302 much better mechanical qualities. Balls are supplied in the passivated situation.
316: Austenitic stainless steel balls with increased corrosion resistance than AISI 304 balls. They display good toughness. AISI 316L has a reduced carbon material (greatest ,030%). Balls are offered in the passivated issue.
420C: Martensitic hardened stainless metal balls, they feature very good hardness, corrosion resistance, wear and abrasion resistance. Balls are offered in the passivated condition.
440C: Martensitic hardened stainless steel balls, they function outstanding hardness, use resistance, floor finishing, slender dimensional tolerances. For that cause this sort of steel is regularly used in precision units. Balls are presented in the passivated issue.
Corrosion Resistance
201: Related to the corrosion resistance of AISI 302/304 materials.
304: Very great corrosion resistance with regard to natural and organic substances, oxidating solutions, foodstuff, sterilizing solutions. Very good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of very hot chloride remedies and to tension corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid answers. AISI 302 displays slightly greatest corrosion resistance with regard to AISI 304/304L stainless steels.
316: Really great corrosion resistance with respect to organic substances, good resistance to several powerful acids (acetic, phosphoric, sulphuric acid) and on sea h2o. They are subjected to pitting and crevice corrosion in existence of hot chloride options and to stress 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: Excellent corrosion resistance in industrial atmosphere, freshwater, steam, alcool, ammonium, numerous oilfield products and natural and organic compounds, dairy merchandise, delicate acid environments. Fairish in foodstuff and alkaline remedies. Reasonable in salt ambiance. It does not resist in contact with sea drinking water and strong acids (even if diluted).
440C: The substance resists to corrosion in make contact with with freshwater, steam, oil, petrol, alcohol. They are subjected to pitting corrosion in sea water environments. Very poor corrosion resistance in acid environments.
Application
201: Particular bearings, automotive factors, switches, die casting products. They are commonly employed in the digital market.
304: Special bearings and pumps, aerosol pumps, gardening and house sprayers, fragrance miniature pumps, seams, health care application valves, agricultural backpack sprayers. They are used in foodstuff, aerospace and military sector.
316: Specific bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber, army, textile market. Programs in photographic units, health care devices, swift couplings, recirculating balls, ink cartridges, jewels.
420C: Particular bearings, anti-friction bearings, special pumps, recirculating balls, lighters, pens, automotive seatbelts & elements.
440C: Precision bearings, anti-friction bearings, special valves, conveyor belts and rollers, ballpoint pens. They are utilized in foodstuff, health care instruments, rapid couplings, recirculating ball bearings, knotting gadgets, oil refinery gadgets.
