Manufacturing Description
 

AISI 302/304/304L STAINLESS Metal BALLS

They show great mechanical attributes, toughness and corrosion resistance. AISI 304L supplies lower carbon content material, AISI 302 greater mechanical traits. Balls are presented in the passivated issue.

 

Purposes

Special bearings and pumps, aerosol pumps, gardening and household sprayers, fragrance miniature pumps, seams, medical application valves, agricultural backpack sprayers. They are employed in foodstuff, aerospace and army sector.

Corrosion Resistance

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

Notes

Property	Description
Hardness*	Balls can be provided in the (1) Cold Labored (HRC 20-39, regular solution) or (2) ANNEALED (HV 100-250, on desire) problems.
Magnetism	Eventual magnetism of AISI 316 balls and in general of all austenitc stainless steels strictly is dependent by the production approach, certain inquiries for not magnetic balls need to priorly documented.
Precision Quality**	On specifical ask for and for big quantities, we can source G10 and G16 precision grade balls. Diameters from three.000 mm to 1/2″.
Precision Quality**	On specifical request we can source G20-24-25-28-forty-forty eight-fifty-sixty-eighty precision grade balls.
