Microstructural Development in HSLA-100 Steel Weld Metals

Abstract

In order to check the validity of the data from the as-received plate samples were re-austenitized, quenched and subsequently tempered for up to 3 hours at 605 deg C. In order to document the long term, high temperature stability of HSLA-100, tempering times were increased up to 48 hours. The microstructures that develop in the coarse-grained heat affected zone (CG-HAZ) of the welds are discussed in this document. At this point, it should be noted that all of the results reported herein are for the 0.04%C version of HSLA-100. We have also examined an 0.02%C version, and the results of these studies (primarily with respect to quenching/tempering and the CG-HAZ) will be submitted shortly.
