A042
Description:
A042 is titanium calcium type of ultra-low carbon Cr23Ni13Mo2 stainless steel electrode, AC and DC can be used. Due to the weld to add the right amount of Mo, it improves the weld metal crack resistance and corrosion resistance.
use:
For the same type of ultra-low carbon stainless steel and dissimilar steel welding.
