Production Description
 

AISI 302/304/304L STAINLESS Steel BALLS

They exhibit excellent mechanical attributes, toughness and corrosion resistance. AISI 304L supplies lower carbon articles, AISI 302 far better mechanical attributes. Balls are offered in the passivated condition.

 

Programs

Stainless steel balls are broadly used in bearings, cars, bikes, bicycles, house appliances, chemical machinery, textile machinery, foodstuff equipment, mining equipment, instruments, and other fields.

Corrosion Resistance

Extremely good corrosion resistance with respect to organic and natural substances, oxidating remedies, foodstuff, sterilizing solutions. Good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of scorching chloride options and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid remedies. AISI 302 demonstrates a bit ideal corrosion resistance with respect to AISI 304/304L stainless steels.

Notes

Property	Description
Hardness*	Balls can be equipped in the (one) Chilly Worked (HRC twenty-39, common product) or (two) ANNEALED (HV one hundred-250, on demand from customers) problems.
Magnetism	Eventual magnetism of AISI 316 balls and in standard of all austenitc stainless steels strictly is dependent by the producing method, certain inquiries for not magnetic balls should priorly described.
Precision Grade**	On specifical ask for and for huge portions, we can source G10 and G16 precision quality balls. Diameters from 3.000 mm to 1/two”.
Precision Quality**	On specifical request we can provide G20-24-twenty five-28-40-48-fifty-60-80 precision grade balls.
