| Weldability | Steel is welded without restrictions. Welding ways: ADS and RDS. For manual arc welding it is recommended to use electrodes TSL-11 filler wire SV-08Х19Н10Б. The same wire is used for argon-arc and arc automatic welding. For electric-arc automatic welding is used the flux an-26. Heat treatment after welding is not required. For joints of NPP equipment recommended automatic arc submerged arc welding and manual argon arc welding with non-consumable electrode (filler or without filler material). To improve the overall corrosion resistance of welded assemblies and relieve residual stresses applied on the hardened air from 950-1050 °C (aged for at least 2.5 minutes/mm of maximum wall thickness, but not less than 1 hour). |
| Propensity to temper brittleness | When heated in the range of 350-750 °C in the ferritic steel component of the processes related to 47 |
| Forging temperature | Start - 1150 °C, the end - 850 °C. |
| Workability by cutting | Close to the machinability of steels 12KH18N9T, 12KH18N10T. |
| Features of heat treatment | Steel products to eliminate the tendency to intergranular corrosion are subjected to hardening regime: heating to 1050±25 °C, exposure during heating for quenching for products with wall thickness up to 10 mm - 30 min, over 10 mm — 20 min + 1 min per 1 mm max thickness cooling in water or air. Products austenite-ferritic steels do not require heat treatment after welding. |
| Propensity to intergranular corrosion | Satisfactory resistance to intergranular corrosion. |
