Stainless Metal Round Beads .5mm .019inch Stainless Metal Balls AISI304 For Drilling Equipment

Generation Description

They exhibit excellent mechanical traits, toughness and corrosion resistance. AISI 304L provides lower carbon articles, AISI 302 greater mechanical attributes. Balls are presented in the passivated issue.


Stainless metal balls are broadly utilised in bearings, cars, bikes, bicycles, family appliances, chemical equipment, textile machinery, meals equipment, mining equipment, instruments, and other fields.

Corrosion Resistance 
Really good corrosion resistance with respect to natural and organic substances, oxidating remedies, foodstuff, sterilizing remedies. Good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of very hot chloride remedies and to tension corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 shows slightly ideal corrosion resistance with respect to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be supplied in the (one) Chilly Labored (HRC 20-39, standard item) or (two) ANNEALED (HV 100-250, on need) circumstances.
Magnetism Eventual magnetism of AISI 316 balls and in common of all austenitc stainless steels strictly relies upon by the manufacturing process, particular inquiries for not magnetic balls should priorly described.
Precision Quality** On specifical request and for massive quantities, we can source G10 and G16 precision grade balls. Diameters from 3.000 mm to 1/two”.
Precision Grade** On specifical request we can supply G20-24-twenty five-28-40-forty eight-50-sixty-eighty precision quality balls.
