Composition of Stellite 3 Powder

Understanding the composition of Stellite 3 Powder is essential to grasp why it performs so well in demanding environments. The alloy is primarily cobalt-based, but it includes other elements that enhance its properties, making it a highly versatile material.

Core Elements in Stellite 3 Powder:

ElementoComposição percentual
Cobalto (Co)50-60%
Cromo (Cr)28-33%
Tungstênio (W)7-10%
Carbono (C)2-2.5%
Níquel (Ni)2-4%
Ferro (Fe)≤ 3%

Cobalt forms the backbone of the alloy, providing excellent wear resistance, while chromium and tungsten add hardness and enhance the material’s ability to resist corrosion and high temperatures. The carbon content contributes to the alloy’s hardness, making it well-suited for wear-prone applications.
