Attribute
201: Cr-Mn stainless steel balls, with homes comparable to AISI 302/304 balls (marginally increased mechanical attributes). Balls are presented in the passivated problem.
304: Unhardened austenitc stainless steel balls, they exhibit great mechanical characteristics, toughness and corrosion resistance. AISI 304L provides reduce carbon content, AISI 302 better mechanical attributes. Balls are offered in the passivated condition.
316: Austenitic stainless steel balls with increased corrosion resistance than AISI 304 balls. They show good toughness. AISI 316L has a lower carbon content material (maximum ,030%). Balls are provided in the passivated situation.
420C: Martensitic hardened stainless steel balls, they attribute good hardness, corrosion resistance, wear and abrasion resistance. Balls are offered in the passivated issue.
440C: Martensitic hardened stainless steel balls, they function exceptional hardness, wear resistance, surface ending, slim dimensional tolerances. For that purpose this kind of steel is usually utilized in precision units. Balls are offered in the passivated problem.
Corrosion Resistance
201: Comparable to the corrosion resistance of AISI 302/304 resources.
304: Really good corrosion resistance with regard to natural substances, oxidating answers, foodstuff, sterilizing solutions. Good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of hot chloride options and to anxiety corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid options. AISI 302 demonstrates slightly very best corrosion resistance with respect to AISI 304/304L stainless steels.
316: Extremely excellent corrosion resistance with regard to organic and natural substances, excellent resistance to numerous powerful acids (acetic, phosphoric, sulphuric acid) and on sea h2o. They are subjected to pitting and crevice corrosion in presence of sizzling chloride answers and to pressure 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 environment, freshwater, steam, alcool, ammonium, many oilfield items and natural compounds, dairy products, gentle acid environments. Fairish in foodstuff and alkaline remedies. Reasonable in salt atmosphere. It does not resist in speak to with sea water and robust acids (even if diluted).
440C: The substance resists to corrosion in speak to 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: Particular bearings, automotive parts, switches, die casting products. They are widely employed in the digital industry.
304: Unique bearings and pumps, aerosol pumps, gardening and household sprayers, perfume miniature pumps, seams, healthcare software valves, agricultural backpack sprayers. They are utilised in foodstuff, aerospace and navy market.
316: Specific bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber, armed forces, textile industry. Apps in photographic gadgets, medical devices, quick couplings, recirculating balls, ink cartridges, jewels.
420C: Unique bearings, anti-friction bearings, special pumps, recirculating balls, lighters, pens, automotive seatbelts & elements.
440C: Precision bearings, anti-friction bearings, specific valves, conveyor belts and rollers, ballpoint pens. They are employed in foodstuff, health care instruments, fast couplings, recirculating ball bearings, knotting products, oil refinery devices.
