5.0mm 0.196inch AISI440c Stainless Steel Balls for Toys 0.509g

5.0mm 0.196inch AISI440c Stainless Steel Balls for Toys 0.509g

 Generation Description

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


Stainless metal balls are extensively used in bearings, cars, motorcycles, bicycles, house appliances, chemical machinery, textile machinery, foodstuff machinery, mining equipment, instruments, and other fields.

Corrosion Resistance 
Really good corrosion resistance with respect to organic and natural substances, oxidating answers, foodstuff, sterilizing remedies. Very good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of sizzling chloride solutions and to pressure corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid answers. AISI 302 displays marginally best corrosion resistance with regard to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be equipped in the (1) Cold Labored (HRC twenty-39, common product) or (2) ANNEALED (HV 100-250, on desire) situations.
Magnetism Eventual magnetism of AISI 316 balls and in basic of all austenitc stainless steels strictly relies upon by the manufacturing method, particular inquiries for not magnetic balls need to priorly reported.
Precision Grade** On specifical request and for big quantities, we can source G10 and G16 precision quality balls. Diameters from three.000 mm to one/two”.
Precision Quality** On specifical request we can source G20-24-twenty five-28-forty-forty eight-fifty-60-80 precision grade balls.
