Stainless steel rutile coated low carbon electrode for use in high strength, unalloyed and heat treatable steels, ferritic Cr and austenitic CrNi steels. Ideal for dissimilar metals, buffer layers on mild steel and low alloyed steels prior to build up or overlaying.
Features and Applications
Rutile coated low carbon electrode for use in high strength unalloyed and heat treatable steels, ferritic Cr and austenitic CrNi steels, austenitic Mn steels
Similar type austenitic stainless steels, dissimilar metals, buffer layers on mild and low alloyed steels prior to build up or overlaying with any stainless electrodes, joining of corrosion resistant stainless steel with mild or low alloy steels, clad steels
Good crack resistance with hard to weld steels
The weld metal contains a high ferrite %
Requirement of re-drying for minimum 2 hours at temperatures between 120°C-200°C
