1.45mm 0.057inch AISI304 Stainless Steel Balls for Energy & Mining 0.011g

1.45mm 0.057inch AISI304 Stainless Steel Balls for Energy & Mining 0.011g

Creation Description

They exhibit good mechanical attributes, toughness and corrosion resistance. AISI 304L provides lower carbon content material, AISI 302 far better mechanical traits. Balls are offered in the passivated problem.


Stainless steel balls are extensively utilised in bearings, automobiles, bikes, bicycles, home appliances, chemical machinery, textile machinery, foodstuff machinery, mining equipment, devices, and other fields.

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


Property  Description
Hardness* Balls can be equipped in the (one) Cold Labored (HRC 20-39, common merchandise) or (2) ANNEALED (HV 100-250, on demand) circumstances.
Magnetism Eventual magnetism of AISI 316 balls and in general of all austenitc stainless steels strictly relies upon by the producing method, 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 Quality** On specifical ask for we can source G20-24-twenty five-28-40-48-fifty-60-80 precision grade balls.
