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

304: Unhardened austenitc stainless metal balls, they screen great mechanical attributes, toughness and corrosion resistance. AISI 304L offers reduced carbon content material, AISI 302 better mechanical attributes. Balls are supplied in the passivated problem.

316: Austenitic stainless steel balls with increased corrosion resistance than AISI 304 balls. They show very good toughness. AISI 316L has a reduce carbon material (greatest ,030%). Balls are provided in the passivated situation.

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

440C: Martensitic hardened stainless metal balls, they attribute remarkable hardness, dress in resistance, area ending, slim dimensional tolerances. For that explanation this type of steel is usually employed in precision devices. Balls are supplied in the passivated issue.

Corrosion Resistance
201: Comparable to the corrosion resistance of AISI 302/304 materials.
304: Quite excellent corrosion resistance with regard to natural substances, oxidating remedies, foodstuff, sterilizing answers. Very good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of very hot chloride options and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid options. AISI 302 displays somewhat ideal corrosion resistance with respect to AISI 304/304L stainless steels.

316: Very good corrosion resistance with regard to natural substances, great resistance to many robust acids (acetic, phosphoric, sulphuric acid) and on sea drinking water. They are subjected to pitting and crevice corrosion in presence of scorching chloride solutions and to anxiety 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: Excellent corrosion resistance in industrial atmosphere, freshwater, steam, alcool, ammonium, many oilfield merchandise and organic compounds, dairy goods, moderate acid environments. Fairish in foodstuff and alkaline options. Reasonable in salt environment. It does not resist in make contact with with sea h2o and powerful acids (even if diluted).

440C: The material resists to corrosion in contact with freshwater, steam, oil, petrol, liquor. They are subjected to pitting corrosion in sea h2o environments. Very poor corrosion resistance in acid environments.

Software
201: Particular bearings, automotive parts, switches, die casting units. They are commonly employed in the electronic sector.

304: Special bearings and pumps, aerosol pumps, gardening and family sprayers, perfume miniature pumps, seams, medical software valves, agricultural backpack sprayers. They are employed in foodstuff, aerospace and army business.

316: Unique bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber, navy, textile industry. Purposes in photographic gadgets, medical devices, swift couplings, recirculating balls, ink cartridges, jewels.

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

440C: Precision bearings, anti-friction bearings, special valves, conveyor belts and rollers, ballpoint pens. They are utilized in foodstuff, healthcare devices, fast couplings, recirculating ball bearings, knotting devices, oil refinery products.
