Manufacturing Description
 

AISI 302/304/304L STAINLESS Steel BALLS

They screen excellent mechanical qualities, toughness and corrosion resistance. AISI 304L supplies lower carbon material, AISI 302 greater mechanical characteristics. Balls are offered in the passivated issue.

 

Programs

Stainless steel balls are extensively used in bearings, cars, bikes, bicycles, home appliances, chemical equipment, textile machinery, meals equipment, mining equipment, instruments, and other fields.

Corrosion Resistance

Very excellent corrosion resistance with regard to organic substances, oxidating remedies, foodstuff, sterilizing solutions. Good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of very hot chloride remedies and to pressure corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid answers. AISI 302 displays marginally best corrosion resistance with respect to AISI 304/304L stainless steels.

Notes

Property	Description
Hardness*	Balls can be supplied in the (1) Chilly Worked (HRC twenty-39, standard product) or (2) ANNEALED (HV 100-250, on demand) situations.
Magnetism	Eventual magnetism of AISI 316 balls and in general of all austenitc stainless steels strictly is dependent by the producing approach, certain inquiries for not magnetic balls ought to priorly documented.
Precision Grade**	On specifical request and for big portions, we can offer G10 and G16 precision quality balls. Diameters from three.000 mm to one/two”.
Precision Grade**	On specifical ask for we can supply G20-24-twenty five-28-forty-forty eight-50-60-80 precision quality balls.
