| Weldability | 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). |
| Macrostructure and contamination | Macrostructure of steel when testing for treated templeto should not have shrinkage, porosity, bubbles, captivity, cracks, fistulas, delaminations, and inclusions, podsadecki segregation and exudation of the square. The defects allowed in scores on scales GOST 10243 must not exceed: a). for metal open arc smelting in the Central porosity, point heterogeneity, and 2 points for each parameter; b). for of metal of electroslag remelting: Central porosity 1 point, point heterogeneity - 2 points;). Pousada segregation and exudation square are not allowed. |
| Microstructure | On demand of the consumer steel is carried out in the control of the α-phase, the amount of which in the steel should not exceed 20%. The number of orders control of the α-phase should not exceed 80% of the total annual supply for THAT 14-1-2476-78. |
| Features of production | Plates on the other 14-1-1337-75 comes in heat-treated according to the recommended regime: Quenching in water or air with 1020-1050 NN the fire °C. Mechanical properties of steel thicker than 20 mm are not controlled. Bars hot rolled and forged on the other 14-1-915-74 are supplied without heat treatment. |
| Features of heat treatment | Steel products to eliminate the tendency to intergranular corrosion are subjected to hardening regime: heating to 1020-1050 NN the fire °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. Products austenite-ferritic steels do not require heat treatment after welding. |
