Material Notes:

Good scaling resistance and can be subjected to reducing sulphur environments without risk. Subject to 475°C embrittlement and grain coarsening at temperatures above 950°C. s-phase may form after long time exposures to temperatures around 650°C.Applications: Mostly used in high temperature applications with sulphurous atmospheres and/or low tensile loads such as for installations within: Chemical industry (drums)Power industry (coal burners)Metalworking industry (heat treatment boxes)Furnace technology (walls, doors)Available in hot rolled plate (Quarto) form.
