Application\/properties:<\/strong><\/p>\n\n\n\n

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\u00b0C Depending on type of base metal and wall thickness, preheating and enter pass temperatures from 100\u00b0C to 400\u00b0C and tempering at 650\u00b0C to 750\u00b0C are advisable. Weld is non-scaling up to 850\u00b0C.<\/p>\n\n\n\n
