Popis:	The microstructure and mechanical properties of a welded joint from heat resistant steel SA-335 P5 have been studied directly after welding (as-welded), after post-weld open-flame heat treatment (PWOFHT), and after post-weld electric heat treatment (PWEHT). The elemental content of the welded joint and Vickers hardness were determined. Tensile and bending tests were conducted. A positive effect of heat treatment (especially, PWEHT) on the mechanical properties and structure of the welded joint was shown. It was established that after the PWEHT, the welded joint from steel P5 meets the material requirements of the petrochemical industry. The use of as-welded joint from this steel is not recommended.
