Characteristic
201: Cr-Mn stainless metal balls, with qualities equivalent to AISI 302/304 balls (somewhat greater mechanical qualities). Balls are supplied in the passivated condition.
304: Unhardened austenitc stainless metal balls, they display excellent mechanical qualities, toughness and corrosion resistance. AISI 304L offers reduce carbon content material, AISI 302 far better mechanical traits. Balls are supplied in the passivated problem.
316: Austenitic stainless steel balls with larger corrosion resistance than AISI 304 balls. They present very good toughness. AISI 316L has a reduce carbon content material (maximum ,030%). Balls are offered in the passivated condition.
420C: Martensitic hardened stainless metal balls, they characteristic great hardness, corrosion resistance, put on and abrasion resistance. Balls are offered in the passivated situation.
440C: Martensitic hardened stainless steel balls, they attribute exceptional hardness, wear resistance, area finishing, narrow dimensional tolerances. For that reason this kind of metal is often employed in precision gadgets. Balls are supplied in the passivated issue.
Corrosion Resistance
201: Related to the corrosion resistance of AISI 302/304 materials.
304: Quite great corrosion resistance with respect to organic and natural substances, oxidating remedies, foodstuff, sterilizing remedies. Very good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of scorching chloride remedies and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 shows a bit best corrosion resistance with regard to AISI 304/304L stainless steels.
316: Quite great corrosion resistance with regard to organic substances, great resistance to several sturdy acids (acetic, phosphoric, sulphuric acid) and on sea h2o. They are subjected to pitting and crevice corrosion in existence of sizzling chloride solutions and to pressure 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: Very good corrosion resistance in industrial atmosphere, freshwater, steam, alcool, ammonium, a number of oilfield merchandise and organic and natural compounds, dairy merchandise, delicate acid environments. Fairish in foodstuff and alkaline solutions. Honest in salt environment. It does not resist in speak to with sea water and strong acids (even if diluted).
440C: The substance resists to corrosion in contact with freshwater, steam, oil, petrol, alcoholic beverages. They are subjected to pitting corrosion in sea water environments. Inadequate corrosion resistance in acid environments.
Software
201: Particular bearings, automotive components, switches, die casting devices. They are widely employed in the electronic market.
304: Special bearings and pumps, aerosol pumps, gardening and household sprayers, perfume miniature pumps, seams, health care application valves, agricultural backpack sprayers. They are utilised in foodstuff, aerospace and armed forces industry.
316: Specific bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber, army, textile sector. Apps in photographic devices, health care devices, quick couplings, recirculating balls, ink cartridges, jewels.
420C: Particular bearings, anti-friction bearings, special pumps, recirculating balls, lighters, pens, automotive seatbelts & components.
440C: Precision bearings, anti-friction bearings, particular valves, conveyor belts and rollers, ballpoint pens. They are used in foodstuff, medical devices, fast couplings, recirculating ball bearings, knotting units, oil refinery products.
