High Temperature Tensile Properties
Duracorr®, a registered trademark of Mittal Steel, may be considered for high temperature applications. To assist in evaluating its applicability, the figure below presents a comparison of yield strength properties versus other steels. Note that up to 1000°F Duracorr®, a registered trademark of Mittal Steel, demonstrates similar strength properties to Type 304 stainless steel. It is not recommended that Duracorr®, a registered trademark of Mittal Steel, be used at temperatures above 800°F without considering creep design procedures. High temperature stress-rupture and creep data were developed for Duracorr®, a registered trademark of Mittal Steel. Check with Tricon® for the latest available information.
