Function
201: Cr-Mn stainless steel balls, with properties similar to AISI 302/304 balls (slightly greater mechanical characteristics). Balls are provided in the passivated problem.
304: Unhardened austenitc stainless metal balls, they screen very good mechanical characteristics, toughness and corrosion resistance. AISI 304L provides reduced carbon content, AISI 302 greater mechanical qualities. Balls are offered in the passivated situation.
316: Austenitic stainless metal balls with higher corrosion resistance than AISI 304 balls. They display great toughness. AISI 316L has a lower carbon content (highest ,030%). Balls are supplied in the passivated condition.
420C: Martensitic hardened stainless metal balls, they feature excellent hardness, corrosion resistance, dress in and abrasion resistance. Balls are supplied in the passivated issue.
440C: Martensitic hardened stainless steel balls, they attribute exceptional hardness, wear resistance, surface area finishing, narrow dimensional tolerances. For that explanation this variety of metal is usually utilized in precision gadgets. Balls are provided in the passivated situation.
Corrosion Resistance
201: Related to the corrosion resistance of AISI 302/304 components.
304: Very good corrosion resistance with regard to natural and organic substances, oxidating remedies, foodstuff, sterilizing solutions. Excellent resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of sizzling chloride options and to pressure corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid remedies. AISI 302 shows marginally very best corrosion resistance with respect to AISI 304/304L stainless steels.
316: Really good corrosion resistance with respect to natural and organic substances, excellent resistance to many powerful acids (acetic, phosphoric, sulphuric acid) and on sea h2o. They are subjected to pitting and crevice corrosion in presence of sizzling chloride solutions 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: Good corrosion resistance in industrial atmosphere, freshwater, steam, alcool, ammonium, a number of oilfield items and organic compounds, dairy items, moderate acid environments. Fairish in foodstuff and alkaline answers. Fair in salt atmosphere. It does not resist in contact with sea h2o and powerful acids (even if diluted).
440C: The materials resists to corrosion in get in touch with with freshwater, steam, oil, petrol, liquor. They are subjected to pitting corrosion in sea water environments. Bad corrosion resistance in acid environments.
Application
201: Specific bearings, automotive components, switches, die casting products. They are widely utilised in the digital business.
304: Specific bearings and pumps, aerosol pumps, gardening and household sprayers, perfume miniature pumps, seams, health-related software valves, agricultural backpack sprayers. They are utilized in foodstuff, aerospace and army industry.
316: Particular bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber, military, textile industry. Purposes in photographic units, health-related devices, rapid couplings, recirculating balls, ink cartridges, jewels.
420C: Unique bearings, anti-friction bearings, specific pumps, recirculating balls, lighters, pens, automotive seatbelts & elements.
440C: Precision bearings, anti-friction bearings, particular valves, conveyor belts and rollers, ballpoint pens. They are utilized in foodstuff, health-related instruments, fast couplings, recirculating ball bearings, knotting devices, oil refinery products.
