Stainless steel electrode CHS042 (A042) comply with: GB / T983 E309LMo-16 AWS A5.4 E309LMo-16 Description: CHS042 rutile type of drug skin ultra-low carbon stainless steel electrode. AC and DC. As the weld proper amount of molybdenum is added, it increases the weld metal crack resistance and corrosion resistance. Uses: low carbon stainless steel materials (such as urea reactor lining) for the same type and dissimilar just welding.
