Stainless Steel Ball AISI 420c G100 25.4mm 1inch Stainless Steel Ball for Valve or Bearings

Stainless Steel Ball AISI 420c G100 25.4mm 1inch Stainless Steel Ball for Valve or Bearings

Generation Description

They exhibit good mechanical traits, toughness and corrosion resistance. AISI 304L offers lower carbon content, AISI 302 far better mechanical traits. Balls are provided in the passivated issue.


Special bearings and pumps, aerosol pumps, gardening and household sprayers, fragrance miniature pumps, seams, health care application valves, agricultural backpack sprayers. They are utilised in foodstuff, aerospace and military industry.

Corrosion Resistance 
Extremely very good corrosion resistance with regard to organic substances, oxidating solutions, foodstuff, sterilizing answers. Excellent resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of very hot chloride answers and to pressure corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid remedies. AISI 302 exhibits slightly very best corrosion resistance with regard to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be equipped in the (one) Chilly Worked (HRC twenty-39, regular item) or (2) ANNEALED (HV 100-250, on demand) problems.
Magnetism Eventual magnetism of AISI 316 balls and in general of all austenitc stainless steels strictly is dependent by the production approach, specific inquiries for not magnetic balls should priorly documented.
Precision Grade** On specifical request and for huge quantities, we can offer G10 and G16 precision quality balls. Diameters from 3.000 mm to 1/2″.
Precision Grade** On specifical ask for we can offer G20-24-twenty five-28-40-forty eight-fifty-60-eighty precision quality balls.
