Properties and Applications

Basic coated stainless steel electrode for welding heat resisting chromium and chromium-nickel steels as well as cast steels. Weld metal deposit is fully austenitic stainless steel, containing 25% chromium and 20% nickel. Suitable for welding heat treatment and industrial fumaces and equipments which are service temperatures up to 1200°C. Weld metal is non-scaling up to 1250°C. Especially high charpy impact energy at low temperatures. Weld metal is not corrosion resistant to sulphurous combustion gases. Used with DCEP.
