Alloy 02Cr8H22C6
Technical characteristics
Alloy 02Х8Н22С6 belongs to the type of high alloyed austenitic steels. It has high resistance against intergranular corrosion of base metal and welded joints in aggressive environments at t° up to 80 °C. It is used in the production of welded equipment for the synthesis of high concentration (85%) nitric acid, nitrophos, phosphoric acid extraction

Production
Alloy 02Х8Н22С6. is melted in electric arc furnaces. The production is normalized by the following technical specifications: 14-1-3233-81; 14-1-5076-91; 14-1-3801-85; 14-1-3164-81; 14-1-3660-83; 14-1-3812-84 и 14-1-1024-81. This material is classified as stainless, corrosion-resistant, common, heat-resistant and heat-resistant steel. This steel fully meets the strict requirements of the state standard and is quite easy to process by cutting, expanding the possibilities of its use. The following types of rolled steel are produced: rounds, tubes, wires, sheets and strips. The temperature during hot forming is 1170 °C at the beginning of the process and reaches about 900 °C on completion.
Welding
Welding is carried out both manually and automatically. During manual arc welding electrodes OZL-24 with a wire rod 02Х17Н14С4 are used. This type of filler material is also used in automatic arc welding and argon arc welding. Final heat treatment is used to protect the finished welds.
