Stainless Steel Feature

201: Cr-Mn stainless steel balls, with properties similar to AISI 302/304 balls (slightly higher mechanical characteristics).

 

Balls are provided in the passivated condition.

304: Unhardened austenitc stainless steel balls, they display good mechanical characteristics, toughness and corrosion resistance.

 

AISI 304L provides lower carbon content, AISI 302 better mechanical characteristics.

 

Balls are provided in the passivated condition.

316: Austenitic stainless steel balls with higher corrosion resistance than AISI 304 balls. They show good toughness.

 

AISI 316L has a lower carbon content (maximum 0,030%). Balls are provided in the passivated condition.

420C: Martensitic hardened stainless steel balls, they feature good hardness, corrosion resistance,

 

wear and abrasion resistance. Balls are provided in the passivated condition.

440C: Martensitic hardened stainless steel balls, they feature remarkable hardness, wear resistance, surface finishing,

 

narrow dimensional tolerances. For that reason this type of steel is frequently used in precision devices.

 

Balls are provided in the passivated condition.

Corrosion Resistance

201: Similar to the corrosion resistance of AISI 302/304 materials.

304: Very good corrosion resistance with respect to organic substances, oxidating solutions, foodstuff, sterilizing solutions.

 

Good resistance with respect to atmospheric corrosion and dyes.

 

They are subjected to pitting and crevice corrosion in presence of hot chloride solutions and to stress corrosion

 

when temperature exceeds 60°C. They do not resist to sulfuric acid solutions.

 

AISI 302 shows slightly best corrosion resistance with respect to AISI 304/304L stainless steels.

316: Very good corrosion resistance with respect to organic substances, good resistance to several strong acids

 

(acetic, phosphoric, sulphuric acid) and on sea water.

 

They are subjected to pitting and crevice corrosion in presence of hot chloride solutions and

 

to stress corrosion when temperature exceeds 60°C.

 

They do not resist in contact with hydrochloric and hydrofluoric acids, aqua regia, iron and magnesium chlorides.

420C: Good corrosion resistance in industrial atmosphere, freshwater, steam, alcool, ammonium,

 

several oilfield products and organic compounds, dairy products, mild acid environments.

 

Fairish in foodstuff and alkaline solutions. Fair in salt atmosphere.

 

It does not resist in contact with sea water and strong acids (even if diluted).

440C: The material resists to corrosion in contact with freshwater, steam, oil, petrol, alcohol.

 

They are subjected to pitting corrosion in sea water environments. Poor corrosion resistance in acid environments.

Application

201: Special bearings, automotive components, switches, die casting devices.

 

They are widely used in the electronic industry.

304: Special bearings and pumps, aerosol pumps, gardening and household sprayers, perfume miniature pumps, seams,

 

medical application valves, agricultural backpack sprayers. They are used in foodstuff, aerospace and military industry.

316: Special bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber,

 

military, textile industry. Applications in photographic devices, medical instruments, quick couplings, recirculating balls,

 

ink cartridges, jewels.

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

440C: Precision bearings, anti-friction bearings, special valves, conveyor belts and rollers, ballpoint pens.

 

They are used in foodstuff, medical instruments, quick couplings, recirculating ball bearings, knotting devices,

 

oil refinery devices.
