Effect of the Operating Temperature of a Steam Methane Reforming Furnace on Structural Changes and Crack Susceptibility in Welding 800HT Nickel Alloy

The long-term operation of 800HT nickel alloy parts of a steam methane reforming furnace at temperatures above 800°C leads to significant embrittlement of the metal, sharp grain growth, and precipitation and coagulation of metal carbides along the grain boundaries. The operation of equipment at lowe...
