Micro-alloyed steel: New standard for reformer tubes

Keywords: [tubes] [metallurgy] [alloy] [reformer]

Reformer furnace tubes are designed to operate under high temperature and pressure. Historically, these tubes exhibit improved creep resistance at higher temperatures. The improvements in creep resistance are directly attributed to micro-alloying elements that combine with the carbon in the tube metallurgy to form carbides. These carbides strengthen the tube metallurgy and limit creep deformation. Present and future developments in heat-resistant alloys are discussed in this article.

A very interesting summary.
By the way, do you mind telling me what are the recommended materials specification for a "waste heat boiler", which design temperature is 950°C.?
