Attribute
201: Cr-Mn stainless steel balls, with homes equivalent to AISI 302/304 balls (a bit greater mechanical traits). Balls are provided in the passivated condition.

304: Unhardened austenitc stainless metal balls, they exhibit excellent mechanical traits, toughness and corrosion resistance. AISI 304L gives lower carbon content, AISI 302 better mechanical characteristics. Balls are offered in the passivated problem.

316: Austenitic stainless steel balls with increased corrosion resistance than AISI 304 balls. They display great toughness. AISI 316L has a lower carbon content (highest ,030%). Balls are supplied in the passivated situation.

420C: Martensitic hardened stainless metal balls, they feature good hardness, corrosion resistance, wear and abrasion resistance. Balls are offered in the passivated situation.

440C: Martensitic hardened stainless steel balls, they characteristic impressive hardness, wear resistance, surface ending, narrow dimensional tolerances. For that reason this type of steel is frequently used in precision products. Balls are presented in the passivated issue.

Corrosion Resistance
201: Comparable to the corrosion resistance of AISI 302/304 components.
304: Quite very good corrosion resistance with regard to natural substances, oxidating remedies, foodstuff, sterilizing answers. Excellent resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of sizzling chloride answers and to anxiety corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 demonstrates a bit ideal corrosion resistance with regard to AISI 304/304L stainless steels.

316: Very excellent corrosion resistance with respect to organic substances, excellent resistance to many strong acids (acetic, phosphoric, sulphuric acid) and on sea water. They are subjected to pitting and crevice corrosion in existence of scorching chloride solutions and to anxiety corrosion when temperature exceeds 60°C. They do not resist in speak to with hydrochloric and hydrofluoric acids, aqua regia, iron and magnesium chlorides.

420C: Great corrosion resistance in industrial environment, freshwater, steam, alcool, ammonium, numerous oilfield items and organic compounds, dairy goods, moderate acid environments. Fairish in foodstuff and alkaline answers. Truthful in salt ambiance. It does not resist in contact with sea drinking water and strong acids (even if diluted).

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

Software
201: Special bearings, automotive elements, switches, die casting gadgets. They are commonly utilized in the electronic market.

304: Special bearings and pumps, aerosol pumps, gardening and household sprayers, perfume miniature pumps, seams, healthcare software 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, armed forces, textile industry. Apps in photographic products, health-related devices, rapid couplings, recirculating balls, ink cartridges, jewels.

420C: Unique 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 utilised in foodstuff, health-related instruments, rapid couplings, recirculating ball bearings, knotting gadgets, oil refinery units.
