DETAILS
LINCORE® 55 Flux-Cored Wire delivers a deposit which resists metal-to-metal rolling or sliding wear as well as mild abrasion. Composition and properties depend upon dilution. Single layer deposit properties depend upon base metal and/or build-up material. Cold parts should be warmed to at least 25ºC (75ºF). Higher preheat of 150 - 260ºC (300 - 500ºF) may be necessary on thick parts or heavy sections. Interpass temperature between 150ºC (300ºF) and 200ºC (400ºF) do not affect the hardness of Lincore® 55 significantly.
