Production Description
 

AISI 302/304/304L STAINLESS Steel BALLS

They display excellent mechanical qualities, toughness and corrosion resistance. AISI 304L offers lower carbon articles, AISI 302 far better mechanical traits. Balls are supplied in the passivated situation.

 

Applications

Unique bearings and pumps, aerosol pumps, gardening and household sprayers, fragrance miniature pumps, seams, healthcare application valves, agricultural backpack sprayers. They are employed in foodstuff, aerospace and military business.

Corrosion Resistance

Extremely good corrosion resistance with respect to natural substances, oxidating remedies, foodstuff, sterilizing remedies. Excellent resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of sizzling chloride answers and to anxiety corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 demonstrates somewhat best corrosion resistance with respect to AISI 304/304L stainless steels.

Notes

Property	Description
Hardness*	Balls can be supplied in the (1) Cold Labored (HRC 20-39, common solution) or (2) ANNEALED (HV a hundred-250, on need) situations.
Magnetism	Eventual magnetism of AISI 316 balls and in basic of all austenitc stainless steels strictly relies upon by the producing procedure, certain inquiries for not magnetic balls must priorly noted.
Precision Quality**	On specifical ask for and for huge portions, we can provide G10 and G16 precision quality balls. Diameters from 3.000 mm to one/two”.
Precision Grade**	On specifical request we can supply G20-24-25-28-forty-forty eight-50-sixty-80 precision quality balls.
