Abstract
A method of producing a nickel alloy clad steel pipe including: providing a hollow cylinder of nickel alloy cladding material and a hollow cylinder of steel, placing the hollow cylinder of the nickel alloy cladding material concentrically inside the hollow cylinder of steel or the hollow cylinder of the steel concentrically inside the hollow cylinder of nickel alloy cladding material to form a composite billet, heating the composite billet to 1121-1260° C., and extruding the composite billet, wherein the nickel alloy cladding material comprises 6.0-12.0 wt. % molybdenum, 19.0-27.0 wt. % chromium, 1.0 wt. % maximum tungsten, 0.6 wt. % maximum aluminum, 0.6 wt. % maximum titanium, 0.001-0.05 wt. % carbon, 0.001-0.035 wt. % nitrogen, 0.001-0.3 wt. % silicon, 1.0 wt. % maximum niobium, 2.5 wt. % maximum iron, 0.5 wt. % maximum manganese, 0.015 wt. % maximum phosphorous, 0.015 wt. % maximum sulfur, 1.0 wt. % maximum cobalt, and the balance nickel and may have a solidus temperature greater than 1312° C.
