Function
201: Cr-Mn stainless steel balls, with homes similar to AISI 302/304 balls (somewhat larger mechanical traits). Balls are offered in the passivated condition.

304: Unhardened austenitc stainless steel balls, they display very good mechanical traits, toughness and corrosion resistance. AISI 304L offers lower carbon content, AISI 302 EPT mechanical attributes. Balls are offered in the passivated condition.

316: Austenitic stainless metal balls with higher corrosion resistance than AISI 304 balls. They present excellent toughness. AISI 316L has a lower carbon content (maXiHu (West EPT) Dis.mum ,030%). Balls are provided in the passivated issue.

420C: Martensitic hardened stainless steel balls, they feature good hardness, corrosion resistance, wear and abrasion resistance. Balls are provided in the passivated problem.

440C: Martensitic hardened stainless metal balls, they function remarkable hardness, use resistance, surface area finishing, nEPT dimensional tolerances. For that explanation this variety of steel is regularly used in precision units. Balls are presented in the passivated situation.

Corrosion Resistance
201: Similar to the corrosion resistance of AISI 302/304 resources.
304: Quite excellent corrosion resistance with respect to organic substances, oXiHu (West EPT) Dis.courting remedies, foodstuff, sterilizing answers. Good resistance with regard 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 sixty degC. They do not resist to sulfuric acid solutions. AISI 302 shows somewhat very best corrosion resistance with respect to AISI 304/304L stainless steels.

316: Quite very good corrosion resistance with respect to natural substances, great resistance to several powerful acids (acetic, phosphoric, sulphuric acid) and on sea water. They are subjected to pitting and crevice corrosion in existence of sizzling chloride remedies and to tension corrosion when temperature exceeds sixty degC. They do not resist in speak to with hydrochloric and hydrofluoric acids, aqua regia, iron and magnesium chlorides.

420C: Great corrosion resistance in EPTT ambiance, freshwater, steam, alcool, ammonium, a number of oilfield merchandise and organic compounds, dairy products, mild acid environments. Fairish in foodstuff and alkaline options. Truthful in salt ambiance. It does not resist in speak to with sea h2o and strong acids (even if diluted).

440C: The content resists to corrosion in speak to with freshwater, steam, oil, petrol, alcoholic beverages. They are subjected to pitting corrosion in sea water environments. Very poor corrosion resistance in acid environments.

Application
201: EPT bearings, automotive factors, switches, die casting units. They are commonly used in the electronic business.

304: EPT bearings and pumps, aerosol pumps, XiHu (West EPT) Dis.Hu (West EPT) Dis.dening and EPTT sprayers, perfume miniature pumps, seams, health care application valves, agricultural backpack sprayers. They are used in foodstuff, aerospace and military market.

316: EPT bearings, pumps and valves, aerosol and dispenser sprayers. UEPTTsed in the foodstuff, paper, chemical, rubber, navy, textile industry. Applications in phXiHu (West EPT) Dis.Hu (West EPT) Dis.raphic devices, medical devices, rapid couplings, recirculating balls, ink cartridges, jewels.

420C: EPT bearings, anti-friction bearings, EPTT pumps, recirculating balls, lighters, pens, automotive seatbelts amp elements.

440C: EPT bearings, anti-friction bearings, EPTT valves, conveyor belts and rollers, ballpoint pens. They are utilised in foodstuff, medical devices, rapid couplings, recirculating ball bearings, knotting gadgets, oil refinery devices.
