A042 stainless steel electrode 
 Description: A042 is a titanium calcium type of ultra-low carbon stainless steel electrode Cr23Ni13Mo2 can be AC ??and DC. As the weld by adding an appropriate amount of Mo, thus improving the weld metal crack resistance and corrosion resistance. 


 Uses: used the same type of ultra-low carbon stainless steel (such as urea reactor lining) and dissimilar steel welding.
