Bohler KW 10-IG description: GMAW solid wire of type G 13 / ER 410 (mod.) predominantly used for surfacing of sealing faces of valves for gas, water, and steam piping systems at service temperatures up to +450°C. The machinability of the weld metal depends largely upon the kind of base metal and degree of dilution. Joint welding of similar 13% chromium steels shows matching colour of the weld metal and very good ability to polishing. Good feeding, welding and wetting characteristics.
