Stellite 25 Cobalt-based alloy electrode and wire
Latest company news about Stellite 25 Cobalt-based alloy electrode and wire

1. Product Introduction

Stellite cobalt base alloys consist of complex carbides in an alloy matrix. They are resistant to wear, galling and corrosion and retain these properties at high temperatures. Their exceptional wear resistance is due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a CoCr alloy matrix.

 

(1).Description

This tungsten strengthened cobalt-chromium alloy is the cast version of the wrought alloy L605. A special low carbon material has been found to have exceptional thermal fatigue resistance and is useful for tools to work hot steel. The alloy also resists hot metal on metal wear.

 

(2).Corrosion Resistance

Stellite alloy 25 is resistant to oxidation and carburization up to 1900°F. The alloy resists wet chlorine at ambient temperatures and is resistant to nitric and hydrochloric acids under certain conditions. Exposure testing is recommended to verify performance.

 

(3).Wear

Stellite alloy 25 forms a protective oxide film during hot metal-on-metal wear which prevents metal transfer and damage due to adhesion. The alloy is resistant to thermal cracking and surface fatigue. Since the micro- structure is relatively free of carbide reinforcement, it is not recommended for low stress or low angle particle erosion service.

 

(4).Process performance and requirements

a.The alloy has satisfactory cold and hot forming properties. The thermal processing temperature ranges from 1200 ℃ to 980℃.

b.The average grain size of the alloy is closely related to the degree of deformation of the forging and the final forging temperature.

c.The alloy can be connected by melt welding, resistance welding and fiber welding.

d.Solid solution treatment of alloy: forgings and forging rods are 1230℃, water-cooled.
