AWS E309MoL-16
Description: A042 is an ultra-low carbon Cr23Ni13Mo2 stainless steel electrode with titanium calcium coating. It can be used for both AC and DC. Due to the addition of an appropriate amount of molybdenum, the crack resistance and corrosion resistance of the deposited metal are improved. Application: For the same type of ultra-low carbon stainless steel materials (such as urea synthesis tower lining) and dissimilar steel welding, etc. Chemical composition of weld metal(%):| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
