AISI 440C Stainless Steel Balls

AISI 440C Stainless Steel Balls

Stainless Steel 440C Balls are martensitic and hardened in nature, the hardness achieved is excellent and also is good wear resistant. The highest surface finishing and tight dimensional tolerances can be manufactured with this material.

Application: High Precision bearings, aerospace, knotting devices, oil and gas industry, quick release couplings, automotive industry, pharma industry and so on.

Steel balls have good corrosion resistance and can withstand oil, petrol, steam and alcohol.
