Production Description
 

AISI 302/304/304L STAINLESS Steel BALLS

They show excellent mechanical traits, toughness and corrosion resistance. AISI 304L gives lower carbon content, AISI 302 better mechanical traits. Balls are provided in the passivated issue.

 

Purposes

Specific bearings and pumps, aerosol pumps, gardening and house sprayers, perfume miniature pumps, seams, medical application valves, agricultural backpack sprayers. They are used in foodstuff, aerospace and military industry.

Corrosion Resistance

Really great corrosion resistance with respect to natural substances, oxidating options, foodstuff, sterilizing options. Good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of sizzling chloride answers and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid answers. AISI 302 displays somewhat greatest corrosion resistance with respect to AISI 304/304L stainless steels.

Notes

Property	Description
Hardness*	Balls can be provided in the (1) Cold Worked (HRC twenty-39, standard item) or (two) ANNEALED (HV one hundred-250, on need) conditions.
Magnetism	Eventual magnetism of AISI 316 balls and in standard of all austenitc stainless steels strictly is dependent by the production procedure, specific inquiries for not magnetic balls must priorly reported.
Precision Quality**	On specifical request and for large quantities, we can provide G10 and G16 precision grade balls. Diameters from 3.000 mm to 1/2″.
Precision Quality**	On specifical ask for we can provide G20-24-twenty five-28-40-48-50-sixty-eighty precision grade balls.
