2.9mm 0.114inch AISI304 Stainless Steel Ball for Bearing Balls 0.099g

 Production Description

They screen good mechanical traits, toughness and corrosion resistance. AISI 304L supplies lower carbon content material, AISI 302 much better mechanical attributes. Balls are supplied in the passivated problem.


Specific bearings and pumps, aerosol pumps, gardening and house sprayers, perfume miniature pumps, seams, health care software valves, agricultural backpack sprayers. They are employed in foodstuff, aerospace and military industry.

Corrosion Resistance 
Extremely very good corrosion resistance with respect to natural and organic substances, oxidating remedies, foodstuff, sterilizing solutions. Great resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of very hot chloride options and to pressure corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid options. AISI 302 shows marginally best corrosion resistance with respect to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be supplied in the (one) Cold Worked (HRC 20-39, common product) or (2) ANNEALED (HV 100-250, on demand) problems.
Magnetism Eventual magnetism of AISI 316 balls and in common of all austenitc stainless steels strictly is dependent by the production method, particular inquiries for not magnetic balls must priorly described.
Precision Quality** On specifical request and for massive quantities, we can offer G10 and G16 precision grade balls. Diameters from three.000 mm to one/two”.
Precision Quality** On specifical ask for we can source G20-24-25-28-40-48-50-60-eighty precision quality balls.
