DURMAT FD 59L

DURMAT® FD 59 L is a flux core wire, which deposits a high CrC-alloy. It can be used whenever high abrasion accompanied by corrosion is expected. It is not recommended for impact wear conditions. URMAT® FD 59 L is deposited crack free by controlling the operational conditions. It is recommended that the work piece be preheated up to 450°C and this temperature maintained throughout the complete welding process. After Welding, the component should be cooled slowly preferably in the furnace. Best results are achieved by welding in two layers. A maximum deposit thickness of 8 mm is recommended. The resulting deposits cannot be heat treated, machined or forged. Before overlaying previously hard faced surfaces a buffer layer of DURMAT® FD 200 K or DURMAT® FD 250 K is recommended.
Application: Hardfacing on pumps, mixers, impellers and screws, particularly when these parts are subject to wear by abrasion and corrosion.
