SS304 SS304L Unhardened Stainless Steel Ball For Perfume Miniature Pumps

Brief Introduction

Unhardened austenitc stainless steel balls, they display good mechanical characteristics,

toughness and corrosion resistance. AISI 304L provides lower carbon content,

AISI 302 better mechanical characteristics. Balls are provided in the passivated condition.

Applications

Special bearings and pumps, aerosol pumps, gardening and household sprayers,

perfume miniature pumps, seams, medical application valves, agricultural backpack sprayers.

They are used in foodstuff, aerospace and military industry.

Corrosion Resistance

Very good corrosion resistance with respect to organic substances, oxidating solutions, foodstuff, sterilizing solutions. Good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of hot chloride solutions and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 shows slightly best corrosion resistance with respect to AISI 304/304L stainless steels.

Notes

Property	Description
Hardness*	Balls can be supplied in the (1) COLD WORKED (HRC 20-39, standard product) or (2) ANNEALED (HV 100-250, on demand) conditions.
Magnetism	Eventual magnetism of AISI 316 balls and in general of all austenitc stainless steels strictly depends by the manufacturing process, specific inquiries for not magnetic balls should priorly reported.
Precision Grade**	On specifical request and for big quantities, we can supply G10 and G16 precision grade balls. Diameters from 3.000 mm to 1/2".
Precision Grade**	On specifical request we can supply G20-24-25-28-40-48-50-60-80 precision grade balls.
