Characteristic
201: Cr-Mn stainless steel balls, with houses comparable to AISI 302/304 balls (marginally larger mechanical qualities). Balls are offered in the passivated condition.
304: Unhardened austenitc stainless metal balls, they screen good mechanical qualities, toughness and corrosion resistance. AISI 304L gives reduced carbon content material, AISI 302 better mechanical characteristics. Balls are supplied in the passivated situation.
316: Austenitic stainless metal balls with increased corrosion resistance than AISI 304 balls. They show excellent toughness. AISI 316L has a reduced carbon content (greatest ,030%). Balls are supplied in the passivated situation.
420C: Martensitic hardened stainless metal balls, they function excellent hardness, corrosion resistance, use and abrasion resistance. Balls are offered in the passivated condition.
440C: Martensitic hardened stainless steel balls, they feature impressive hardness, wear resistance, floor finishing, slim dimensional tolerances. For that reason this variety of metal is regularly utilised in precision devices. Balls are offered in the passivated problem.
Corrosion Resistance
201: Related to the corrosion resistance of AISI 302/304 components.
304: Quite good corrosion resistance with regard to organic substances, oxidating answers, foodstuff, sterilizing options. Very good 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 stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 shows somewhat very best corrosion resistance with regard to AISI 304/304L stainless steels.
316: Really good corrosion resistance with regard to organic substances, good resistance to several robust acids (acetic, phosphoric, sulphuric acid) and on sea drinking water. They are subjected to pitting and crevice corrosion in presence of very hot 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: Great corrosion resistance in industrial atmosphere, freshwater, steam, alcool, ammonium, a number of oilfield products and organic and natural compounds, dairy products, gentle acid environments. Fairish in foodstuff and alkaline remedies. Truthful in salt ambiance. It does not resist in get in touch with with sea water and strong acids (even if diluted).
440C: The materials resists to corrosion in speak to with freshwater, steam, oil, petrol, liquor. They are subjected to pitting corrosion in sea h2o environments. Poor corrosion resistance in acid environments.
Software
201: Specific bearings, automotive parts, switches, die casting devices. They are widely used in the electronic sector.
304: Unique bearings and pumps, aerosol pumps, gardening and household sprayers, perfume miniature pumps, seams, health care application valves, agricultural backpack sprayers. They are employed in foodstuff, aerospace and army business.
316: Particular bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber, navy, textile sector. Programs in photographic units, health care devices, fast couplings, recirculating balls, ink cartridges, jewels.
420C: Specific bearings, anti-friction bearings, special pumps, recirculating balls, lighters, pens, automotive seatbelts & factors.
440C: Precision bearings, anti-friction bearings, unique valves, conveyor belts and rollers, ballpoint pens. They are used in foodstuff, health care instruments, swift couplings, recirculating ball bearings, knotting gadgets, oil refinery products.
