| Weldability | Without restrictions. Welded joints made by other methods, in addition to spot welding, prone to intergranular corrosion. To increase the resistance to brittle destruction in kolosovo the zone of the welded joints operating at temperatures above 500 °C welded assemblies are subjected to tempering in air 970-1020 °C (aged for at least 2.5 minutes/mm of maximum wall thickness, but not less than 1 hour). In the presence of hard surfacing in welded assemblies to produce a stabilizing annealing at a temperature of 950-980 °C (aged for at least 2 h), cooling with the furnace or with the furnace to 300 °C and then in air. To relieve residual stresses of welded assemblies, complex configuration, apply leave in 585-615 °C with air cooling, if the temperature of the product does not exceed 500 °C. |
| Forging temperature | Start - 1200 °C, the end - 850 °C. the cross Sections up to 350 mm cooled in air. |
| Macrostructure and contamination | Macrostructure of steel shall be no traces of shrinkage, delamination, foreign inclusions. |
| 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. |
| Corrosion resistance | The steel should not have the tendency to intergranular corrosion. |
