Weldability Limited-weldability requires primene combined welding techniques.
Macrostructure and contamination The macrostructure of the steel on the other 14-1-3303-82 should not be visible without using the magnifying devices of the traces of shrinkage, bubbles, cracks, and slag inclusions. Macrostructure and surface quality of the sheets on the other 14-1-5056-91 must meet M2a-M3A group surface finish GOST 5582.
Microstructure The contents of alpha phase in the rental should not exceed 0.5 points. Steel on the other 14-1-3303-82 controlled for the content of alpha-phase. The contents of alpha phase shall not exceed 2.0 points.
Features of heat treatment Products hromonikelevoj steel stabilized with titanium, to remove residual stresses and prevent stress corrosion cracking may be subjected to heat treatment according to the requirement stipulated in the draft mode which should be agreed with specialized organization. Steel products are subjected to hardening in order to improve the overall corrosion resistance and ductility, to eliminate the tendency to intergranular corrosion. Hardening is performed according to the mode: heating up to 1100-1120 °C, cooling in water or air. 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. Products with wall thickness up to 10 mm is to be cooled in the air, more than 10 mm in water. Welded parts of complex configuration in order to avoid the leash is to be cooled in the air. To give steel the greatest plasticity and the elimination of the structure of the Sigma phase quenching is recommended when heated to the upper limit. Heat treatment nesvorny products to relieve internal stresses and prevent stress corrosion cracking should be carried out in the following mode: heating up to 900±10°C, exposure time of 2-3 h, air cooling. Welded components manufactured from steel hromonikelevoj with the use of unregulated electrodes, to remove residual stresses and prevent stress corrosion cracking should be subjected to heat treatment regime: heating to a 1020-1060 °C, exposure 2 h, air cooling. Products for welded low carbon pure austenitic electrodes, heat-treated to relieve residual stresses and prevent stress corrosion cracking should be carried out according to mode: heating to a 1020-1060 °C, exposure 2 h, cooling with the furnace to 300 °C, then in air. Products, welded electrodes, stabilized by niobium, should be termoobrabotki to relieve residual stresses and prevent stress corrosion cracking according to the mode: heating up to 1100-1140 °C, exposure 2 h, cooling with the furnace to 300 °C, then in air.
Corrosion resistance The corrosion rate of hire should not exceed 0.5 mm/year. Steel 03KH17N14M3 has a high resistance against intergranular corrosion and knife than steel brands 08KH17N15M3T and 10X17H13M2T.
Propensity to intergranular corrosion Bars on the other 14-1-3303-82 should not possess the propensity to intergranular corrosion in the hardened state.
