3.175mm 1 8″ AISI304 Stainless Steel Balls for Bearings, Stamping Hydraulic Parts 0.130g

Production Description

They display good mechanical characteristics, toughness and corrosion resistance. AISI 304L supplies lower carbon content material, AISI 302 far better mechanical attributes. Balls are provided in the passivated issue.


Specific bearings and pumps, aerosol pumps, gardening and home sprayers, fragrance miniature pumps, seams, health-related application valves, agricultural backpack sprayers. They are employed in foodstuff, aerospace and armed forces business.

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


Property  Description
Hardness* Balls can be supplied in the (one) Chilly Labored (HRC twenty-39, standard item) or (two) ANNEALED (HV a hundred-250, on demand from customers) circumstances.
Magnetism Eventual magnetism of AISI 316 balls and in standard of all austenitc stainless steels strictly depends by the production method, distinct inquiries for not magnetic balls should priorly described.
Precision Grade** On specifical ask for and for large quantities, we can provide G10 and G16 precision grade balls. Diameters from 3.000 mm to 1/two”.
Precision Grade** On specifical ask for we can source G20-24-25-28-40-48-fifty-sixty-80 precision quality balls.
