Product Description

Product Name:Good comment on the quality Stellite 1 / 6/12 / 21 cobalt based alloy welding wire stellite 6 welding electrode ERCoCr-A

Product description:         

 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.

 

Cobalt-Based Alloy Bare Rod: 
- AWS RCoCr-C (Stellite 1) 
- AWS RCoCr-A (Stellite 6) 
- AWS RCoCr-B (Stellite 12)

AWS RCoCr-C 
It has excellent wear and heat resistance at high temperature.
Recommended use for making valve seal inserts , rotating sealing ring, drill heads, cutter edge ,etc

 

AWS RCoCr-A 
The most widely used Cobalt Alloy with good mechanical 
properties at different temperatures,  Recommended use 
for making valve seat material, hot shear blade, high temperature valve , turbine blade ,etc.

 

AWS RCoCr-B 
It has excellent resistance on high heat, corrosion 
and abrasion.  Recommended use for making high-
pressure valve, shear edge, sawteeth, etc.

 

AWS RCoCr-E 

It has excellent resistance on high heat, corrosion 
and abrasion.  Recommended use for making fuild valve,

brass casting die , vlave seat, etc.
