Generation Description
 

AISI 302/304/304L STAINLESS Steel BALLS

They show excellent mechanical attributes, toughness and corrosion resistance. AISI 304L gives lower carbon content material, AISI 302 far better mechanical attributes. Balls are supplied in the passivated situation.

 

Purposes

Stainless steel balls are broadly used in bearings, vehicles, motorcycles, bicycles, home appliances, chemical equipment, textile equipment, food equipment, mining equipment, instruments, and other fields.

Corrosion Resistance

Very very good corrosion resistance with respect to organic and natural substances, oxidating remedies, foodstuff, sterilizing solutions. Great resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of hot chloride answers and to pressure corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid answers. AISI 302 shows somewhat greatest corrosion resistance with regard to AISI 304/304L stainless steels.

Notes

Property	Description
Hardness*	Balls can be equipped in the (one) Chilly Labored (HRC twenty-39, standard solution) or (2) ANNEALED (HV 100-250, on need) circumstances.
Magnetism	Eventual magnetism of AISI 316 balls and in common of all austenitc stainless steels strictly is dependent by the manufacturing approach, specific inquiries for not magnetic balls need to priorly reported.
Precision Quality**	On specifical request and for large quantities, we can supply G10 and G16 precision quality balls. Diameters from three.000 mm to one/2″.
Precision Quality**	On specifical request we can source G20-24-twenty five-28-forty-forty eight-50-sixty-eighty precision grade balls.
