Potential Ultraweldable Steels for Truck Castings

Tests were performed to determine the ultraweldability (i.e., improved steel material which does not require preheating or post heating during manufacturing or during reconditioning) of five steels that were identified during previous Federal Railroad Administration (FRA) research conducted by Transportation Technology Center, Inc. (TTCI). The five steels selected for evaluation for this work were: HSLA 65, HSLA 100, HY-80, LCC, and LC3. Testing was performed at the Transportation Technology Center (TTC) in Pueblo, CO, and Ohio State University from July 2016 to late 2017. The HSLA 65 and HSLA 100 steels met the requirements for ultraweldability. These steels can be welded without preheat or post weld heat treatment. They will also have a very low occurrence of hydrogen-induced cracking.
