Technological properties

Name The value
Weldability Without restrictions. Welding method: SMAW - electrodes OzL-8, OzL-12 on wires 02Х19Н9, CCC, ESW. Recommended subsequent heat treatment. Welded joints made by other methods, in addition to spot welding, prone to intergranular corrosion.
Forging temperature Start - 1200 °C, the end - 850 °C. the cross Sections up to 300 mm are cooled in stacks on the air.
Features of heat treatment Steel used for products, not subjected to welding is designed to work in environments do not cause intergranular corrosion. To increase the resistance against General corrosion and eliminate the tendency to intergranular corrosion and to improve the ductility of the workpiece material is subjected to annealing regime: heating to 1050-1100 °C, cooling in water. The holding time at the heating for hardening to products with a wall thickness up to 10 mm - 30 min, over 10 mm - 20 min + 1 min per 1 mm maximum thickness.
