4122 HL-Kb SMAW Stick Electrodes




4122 HL-Kb

 
TYPE 
High recovery, corrosion resistant stainless steel stick electrode
APPLICATIONS 
Hardfacing shafts from stainless steel parts, molt repairs, rebuilding pump parts etc. Suitable for plating and joining equal and similar ferritic Cr-steels and cast steels. This alloy is specially suitable for sealing surfaces on water-, steam and gas-valves, especially for sulphuric gases.
PROPERTIES 

Proper weldings are subject to the recommended heat treatment. The deposit is resistant to seawater, thin acids and scale resistant in air and oxidizing gases up to 950°C . The weld deposit can be tempered and also can sustain working temperatures up to 450° C. and will offer scale resistance up to much higher temperatures. Preheating is recommended at 150 - 350° C. depending on the thickness of the base metal. Similar base metals should be pre-heated at 300° C to 400° C.
