Solderpro *posted on May 17, 2024* i second @metallurgyexpert on the importance of zinc chloride-based fluxes. Additionally, I've used hangzhou Weldpro flux with great success. It's particularly good for high-temperature applications and provides a clean finish. However, make sure to thoroughly clean the stainless steel before applying the flux to get the best results. Any contaminants on the surface can significantly affect the quality of the soldering.
