 The hardness of steel balls is very important for the applications of steel balls. KN steel ball pay high attention on the inspection of hardness of steel balls of each lot production. The report of hardness test of steel balls are issued to the customers after each shipping.

From 0.5mm to 3.5mm balls are our advantage

Chrome steel   AISI52100 100Cr6  Gcr15  

Bearing steel  balls are hardened and tempered through their entire diameter to insure uniform structure and hardness. Ball hardness is controlled within a range of HRC 60 - 67 as measured on a parallel surface.

Stainless steel  offer excellent corrosion resistance in organic, acid, industrial and marine environments. The non magnetic properties combined with exceptionally high toughness at all temperatures make these steels an excellent selection with many applications. AISI 316 stainless steel offers superior corrosion resistance due to the higher nickel and molybdenum content.
