WELDING PROPERTIES OF CHROMIUM-NICKEL-MOLYBDENUM HARDENABLE STAINLESS STEELS
BS>Semiaustenitic hardenable stainless steels types AM-350 and AM-355 were found to have excellent weldability by the same techniques and processes that are used for austenitic stainiess steels. By appropriate low-temperature postweld heat treatments, the weld and base metals may be transformed to a high- strength tempered martensitic structure. Both alloys have welded and hardened strengths equal to 90 to 100% of the base-metal strengths. The welded joints also possess excellent ductility after hardening. In addition, the hardening of the alloys is not produced by elements that are generally incompatible to welding in stainless steels, such as aluminum, beryllium, phosphorus, or titanium. These two factors give the steels considerably better resistance to hot cracking during welding than other hardenable stainless steels. (J.H.M.)
