Manufacturing Description
 

AISI 302/304/304L STAINLESS Steel BALLS

They screen good mechanical traits, toughness and corrosion resistance. AISI 304L offers lower carbon material, AISI 302 greater mechanical qualities. Balls are supplied in the passivated issue.

 

Purposes

Particular bearings and pumps, aerosol pumps, gardening and home sprayers, fragrance miniature pumps, seams, health-related software valves, agricultural backpack sprayers. They are utilised in foodstuff, aerospace and army sector.

Corrosion Resistance

Quite excellent corrosion resistance with respect to organic and natural substances, oxidating options, foodstuff, sterilizing answers. Excellent resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of scorching chloride remedies and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid remedies. AISI 302 displays marginally greatest corrosion resistance with respect to AISI 304/304L stainless steels.

Notes
