The heat-resistant sheet 02Х8Н22С6( EP 794ВД ) 5x1000x2000 mm The use of steel 02Х8Н22С6 02Х8Н22С6 steel used for the manufacture of welded chemical equipment operating under action of concentrated nitric acid at high temperatures (85% concentration and higher temperature up to 100 °C). Steel smelted with the use of special methods of melting: electroslag remelting, plasma arc and vacuum-arc remelting. The standards and specifications for steel 02Х8Н22С6 THAT 14-1-1024-81 ; THAT 14-1-3164-81 ; THAT 14-1-3233-81 ; THAT 14-1-3660-83 ; THAT 14-1-3801-85 ; THAT 14-1-3812-84 ; THAT 14-1-5076-91 ; Chemical composition of steel 02Х8Н22С6 C Cr Fe Mn Ni P S Si ≤0,02 7,5-10 DOS. ≤0,6 21-23 ≤0,03 ≤0,02 5,4-6,7 Mechanical properties of steel 02Х8Н22С6 Technological parameters 02Х8Н22С6 The temperature interval of hot plastic deformation of steel 02Х8Н22С6 is 1150-850 °C, hot and cold steel as well is subjected to bending, and stamping. The recommended heat treatment regime: quenching from 1050 °C in water; the heating time and aging set at the rate of 2 min/mm of thickness of the semifinished product or articles. The same treatment is used for removing the work hardening after hot and cold plastic deformation. Welding of steel 02Х8Н22С6 02Х8Н22С6 steel is welded by manual and automatic welding. For manual arc welding using electrodes OzL-24 with wire of steel 02Х17Н14С4. For automatic arc and manual arc welding recommended wire, steel 02Х8Н22С6. The corrosion rate of welded joints made by all these methods, in 98% HNO3 at 100 °C is 0.22 mm/year. In order to avoid the tendency of welded joints to intergranular corrosion after welding equipment must be subjected to heat treatment (hardening from 1050 °C in water).
