Manufacturing Description
 

AISI 302/304/304L STAINLESS Steel BALLS
They screen great mechanical attributes, toughness and corrosion resistance. AISI 304L supplies lower carbon content, AISI 302 much better mechanical attributes. Balls are provided in the passivated condition.

Applications
Unique bearings and pumps, aerosol pumps, gardening and house sprayers, perfume miniature pumps, seams, health-related application valves, agricultural backpack sprayers. They are utilized in foodstuff, aerospace and military industry.

Corrosion Resistance 
Really good corrosion resistance with respect to organic substances, oxidating options, foodstuff, sterilizing options. Excellent resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of sizzling chloride answers and to anxiety corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid answers. AISI 302 demonstrates a bit best corrosion resistance with regard to AISI 304/304L stainless steels.
