Techalloy AK-10 description: Techalloy AK-10 is a low alloy steel welding wire developed for welding of high strength steels with adequate ductility at low temperatures. The hardness of the undiluted weld will be less than 235 BHN. The requirement of heat and inter-pass temperatures should be determined taking the base plate chemistry and thickness into consideration.
Note: Mechanical properties of welds listed below are greatly influenced by the preheat, inter-pass temperature, the heat input and the post-weld heat treatment.
