DUR E 400 CrMo SMAW Stick Electrodes




DUR E 400 CrMo

 
TYPE 
Basic coated electrode for rebuilding heat resistant machine parts and buffer layers.
APPLICATIONS 
Hardfacing, rebuilding, overlays, machine parts, wheels, conveyors, crossings, bufferlayers prior to hardfacing etc
PROPERTIES 

Outstanding alloy against high impact combined with abrasion including metal to metal friction and increased working temperatures upto 550°C. Due to the high resistance to cracking and toughness, all weld metal requires no buffer layer except on materials considered critical. Suited for wear parts subject to heavy impact and shock. The weld metal is machinable with carbide tip tools, hardening is possible. The maximum hardness is dependent on the base metal and is often achieved in the first layer.
