AWS D10.4 RECOMMENDED PRACTICES FOR WELDING AUSTENITIC CHROMIUM - NICKEL STAINLESS STEEL PIPING AND TUBING
This document presents a detailed discussion of the metallurgical characteristics and weldability of many grades of austenitic stainless steel used in piping and tubing. The delta ferrite content as expressed by ferrite number (FN) is explained. and its importance in minimizing hot cracking is discussed. A number of Figures and Tables illustrate recommended joint designs and procedures. Appendix A presents information on the welding of high-carbon stainless steel cast pipe fittings.
