4893 Kb (253MA) SMAW Stick Electrodes




4893 Kb (253MA)

 
TYPE 
Rutile coated electrode for heat resistant stainless steel SMAW welding.
APPLICATIONS 
Joining and cladding high heat resistant CrNi-steels of the same kind such as heat treatment equipment and chemical installations.
PROPERTIES 

High corrosion resistance and excellent weldability on both AC and DC+. The weld deposit is scale and oxidation resistant up to 950ºC. Interpass temperature should be kept below 150ºC.
