Weldability	Difficult weldability of the steel. In the case of welding electrodes type e-08Х19Н10Г2МБ (stamps EA 898/21 B, etc.) to relieve residual stresses in welded assemblies: a) working at 350 °C and above; b) operating at temperatures above 350 °C, if the hardening is impractical to apply a stabilizing annealing at 850-920 °C (extract after heating the batch for at least 2 hours). To improve the overall corrosion resistance relieve residual stresses in welded assemblies used annealing welded assemblies in air, 1140-1160 °C.
