Application/properties:

Electrode for welding of stainless and heat resistance chromium steels or cast steels having a chromium, content of up to 13%. It is used for corrosion and abrasion resistance surfacing welds (contact surfaces of gas, water and steam fittings) subjected to operation temperatures up to 450°C Depending on type of base metal and wall thickness, preheating and enter pass temperatures from 100°C to 400°C and tempering at 650°C to 750°C are advisable. Weld is non-scaling up to 850°C.
