Stellite 21 rod hardfacing cobalt based welding material

PRODUCT INTRODUCTION:

WISDOM Stellite's™ cobalt base alloys are available as cobalt rods, cobalt electrodes, cobalt wire and cobalt powder.  Cobalt alloys are used primarily for wear applications, our cobalt alloys can be applied by any known fusion welding process or HVOF spraying proess and are particularly well-suited for hardfacing applications.  Cobalt alloys are the most widely used wear resistant hardfacing materials available.  Their unique combination of wear resistance, strength and corrosion resistance make them adaptable to many harsh environments.  Cobalt alloys are selected for their excellent resistance to the widest combination of wear types including adhesive wear, abrasion, erosion, contact fatigue, thermal shock, cavitation wear, corrosion and oxidation.  The degree to which the cobalt alloys retain these properties assures their unique position in the wear technology field.

StelliteTM 1 is a hardfacing alloy possessing excellent abrasion and corrosion resistance for applications such as pump sleeves, rotary seal rings, wear pads, expeller screws and bearing sleeves. It retains its hardness at temperatures in excess of 760°C (1400°F).

          
StelliteTM 1 contains a high proportion of hard, wear resistant 
primary carbides. These render the alloy well suited to applications 
involving extreme low-angle erosion and severe abrasion, with some 
sacrifice in toughness. Compared to other StelliteTM alloys it is more 
crack-sensitive, and care should be taken to minimize the cooling 
stresses experienced during casting and hardfacing processes. Due 
to its high hardness and wear resistance, StelliteTM 1 should only be 
finished by grinding.

           
CORROSION RESISTANCE:

           
StelliteTM 1 has good general corrosion resistance. The typical 
electrode potential in sea water at room temperature is approx. 
-0.4 V (SCE). StelliteTM 1 corrodes primarily by a pitting mechanism 
and not by general mass loss in seawater and chloride solutions. 
More detailed information regarding corrosion resistance can be 
provided on request.
