Carburization
RA333 was originally developed to withstand high temperature carburizing service. It is one of the most carburization resistant materials available. Because of this ability RA333 has been the choice for all types of applications that require heavily carburizing atmospheres. Fabrications including radiant tubes, corrugated boxes and furnace belt pins have all been made from RA333 to withstand the high carbon potentials within these atmospheres. Resistance to metal dusting environments can be attributed to the alloying elements of silicon and tungsten. Simply having a high temperature alloy with chromium and nickel without these elements would be insufficient for a metal dusting application. Along with alloy chemistry, metal dusting resistance is influenced by grain size. A finer grain size greatly increases the rate at which chromium can diffuse to the surface to form a protective film.
