Basic type stainless steel electrode with high recovery, which is used for welding of 12-14% Cr and 3-4% Ni containing stainless and heat resistant chromium steels or cast steels. Deposits martensitic stainless steel weld metal. Also suitable for corrosion and abrasion resistant surfacing of contact surfaces of gas, water, sea water and steam fan, fan blades and fittings in hydro-electric plants and continuous casting rolls. Used with DCEP. For wall thickness over 10 mm preheating to max. 150°C and after welding tempering or normalizing + tempering are recommended. Especially in joint welding a buffer layer with EI 312 or EIS 307 electrode is advisable.
