201: Cr-Mn stainless metal balls, with houses similar to AISI 302/304 balls (a bit increased mechanical qualities). Balls are presented in the passivated issue.

304: Unhardened austenitc stainless metal balls, they show very good mechanical attributes, toughness and corrosion resistance. AISI 304L supplies reduce carbon content, AISI 302 far better mechanical attributes. Balls are supplied in the passivated issue.

316: Austenitic stainless metal balls with greater corrosion resistance than AISI 304 balls. They display great toughness. AISI 316L has a reduce carbon content material (optimum ,030%). Balls are presented in the passivated condition.

420C: Martensitic hardened stainless steel balls, they function great hardness, corrosion resistance, wear and abrasion resistance. Balls are provided in the passivated condition.

440C: Martensitic hardened stainless metal balls, they attribute outstanding hardness, use resistance, area finishing, slender dimensional tolerances. For that reason this type of metal is frequently utilized in precision units. Balls are presented in the passivated condition.

Corrosion Resistance
201: Related to the corrosion resistance of AISI 302/304 supplies.
304: Extremely excellent corrosion resistance with regard to organic substances, oxidating answers, foodstuff, sterilizing options. Very good resistance with regard to atmospheric corrosion and dyes. 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 to sulfuric acid answers. AISI 302 exhibits somewhat greatest corrosion resistance with respect to AISI 304/304L stainless steels.

316: Extremely very good corrosion resistance with respect to natural substances, excellent resistance to several sturdy acids (acetic, phosphoric, sulphuric acid) and on sea water. They are subjected to pitting and crevice corrosion in existence of scorching chloride remedies and to tension 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 environment, freshwater, steam, alcool, ammonium, several oilfield goods and natural compounds, dairy products, moderate acid environments. Fairish in foodstuff and alkaline solutions. Reasonable in salt atmosphere. It does not resist in get in touch with with sea water and sturdy acids (even if diluted).

440C: The materials resists to corrosion in speak to with freshwater, steam, oil, petrol, alcoholic beverages. They are subjected to pitting corrosion in sea h2o environments. Poor corrosion resistance in acid environments.

201: Specific bearings, automotive elements, switches, die casting devices. They are extensively utilised in the electronic business.

304: Special bearings and pumps, aerosol pumps, gardening and house sprayers, fragrance miniature pumps, seams, healthcare software valves, agricultural backpack sprayers. They are utilized in foodstuff, aerospace and navy sector.

316: Special bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber, army, textile industry. Programs in photographic units, healthcare devices, quick couplings, recirculating balls, ink cartridges, jewels.

420C: Unique bearings, anti-friction bearings, unique pumps, recirculating balls, lighters, pens, automotive seatbelts & elements.

440C: Precision bearings, anti-friction bearings, particular valves, conveyor belts and rollers, ballpoint pens. They are utilised in foodstuff, health-related instruments, rapid couplings, recirculating ball bearings, knotting gadgets, oil refinery units.
