Manufacturing Description
 

AISI 302/304/304L STAINLESS Metal BALLS

They show great mechanical qualities, toughness and corrosion resistance. AISI 304L offers lower carbon material, AISI 302 better mechanical attributes. Balls are offered in the passivated issue.

 

Applications

Stainless steel balls are widely used in bearings, automobiles, bikes, bicycles, house appliances, chemical equipment, textile equipment, food equipment, mining machinery, devices, and other fields.

Corrosion Resistance

Quite good corrosion resistance with regard to organic and natural substances, oxidating solutions, foodstuff, sterilizing solutions. Excellent resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of hot chloride remedies and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid remedies. AISI 302 exhibits somewhat ideal corrosion resistance with regard to AISI 304/304L stainless steels.

Notes
