| Weldability |
Limited weldability of high-alloyed steel. Requires heat treatment before welding (on leave of absence at 650-710 °C with cooling in air or quenching in water 1050-1100 °C), preheating to 200-300 °C of the welded parts. After welding to relieve stresses and reduce the hardness of the parts of a welded joint subjected to vacation at 650-710 °C. |
