Abstract

This WRC Bulletin records the data used to gain approval of ASME and API for application of Alloy 115, UNS K91060 (T115) at elevated temperatures.  All data and property equations are provided herein in both US Customary and Metric units.  Included in the data collections and curve fits are yield and tensile strengths, Larson-Miller stress-rupture equations and the Omega Coefficients and corresponding strain rates based on creep data for the stresses and temperatures included.  Also contained within this Bulletin are available data for welded joints, intended to demonstrate the suitability of welded constructions of Alloy 115 for elevated temperature service, and establish modifications to the provided base metal properties to account for the behavior of welded joints.
