    How To Weld 4140 Steel WELDING ANSWERS

    The best way to prevent cracking would be to anneal the 4140 part before welding. That is not always feasible. You can weld 4140 Q&T following the same guidelines as for regular 4140 on this post. However, you must know that you will lose the Q&T properties after welding. If these are critical they most be restored through PWHT.Steel 42CrMo4:characteristics, properties, analogues Steel grade 42CrMo4 is popular in the machine building industry and is used to make high-strength parts of compressors, turbines, working elements of heavy ground and underground equipment, and parts of agricultural machines. Welding. Steel grade 42CrMo4 has low weldability due to high crack sensitivity.
