Function
201: Cr-Mn stainless steel balls, with homes related to AISI 302/304 balls (a bit increased mechanical qualities). Balls are presented in the passivated situation.

304: Unhardened austenitc stainless metal balls, they exhibit very good mechanical qualities, toughness and corrosion resistance. AISI 304L supplies decrease carbon articles, AISI 302 much better mechanical attributes. Balls are supplied in the passivated issue.

316: Austenitic stainless metal balls with increased corrosion resistance than AISI 304 balls. They show excellent toughness. AISI 316L has a lower carbon content (optimum ,030%). Balls are presented in the passivated problem.

420C: Martensitic hardened stainless steel balls, they characteristic good hardness, corrosion resistance, put on and abrasion resistance. Balls are supplied in the passivated condition.

440C: Martensitic hardened stainless metal balls, they characteristic outstanding hardness, use resistance, surface finishing, slim dimensional tolerances. For that explanation this sort of steel is usually used in precision products. Balls are offered in the passivated problem.

Corrosion Resistance
201: Similar to the corrosion resistance of AISI 302/304 supplies.
304: Quite great 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 scorching chloride options and to tension corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid options. AISI 302 demonstrates a bit ideal corrosion resistance with regard to AISI 304/304L stainless steels.

316: Quite excellent corrosion resistance with respect to organic substances, great resistance to several powerful acids (acetic, phosphoric, sulphuric acid) and on sea h2o. They are subjected to pitting and crevice corrosion in existence of scorching chloride remedies 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 atmosphere, freshwater, steam, alcool, ammonium, many oilfield merchandise and natural and organic compounds, dairy products, delicate acid environments. Fairish in foodstuff and alkaline options. Truthful in salt atmosphere. It does not resist in make contact with 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, alcohol. They are subjected to pitting corrosion in sea h2o environments. Poor corrosion resistance in acid environments.

Application
201: Specific bearings, automotive parts, switches, die casting devices. They are commonly utilised in the digital market.

304: Particular bearings and pumps, aerosol pumps, gardening and household sprayers, perfume miniature pumps, seams, health-related software valves, agricultural backpack sprayers. They are used in foodstuff, aerospace and armed forces business.

316: Specific bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber, army, textile industry. Apps in photographic units, medical devices, rapid couplings, recirculating balls, ink cartridges, jewels.

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

440C: Precision bearings, anti-friction bearings, specific valves, conveyor belts and rollers, ballpoint pens. They are employed in foodstuff, medical devices, fast couplings, recirculating ball bearings, knotting devices, oil refinery gadgets.
