Welding
The following types of welding are possible: manual, automatic with flux, under gas shielding. For manual electric-arc welding, there are used electrodes OK 61.30, ОК 67.15 with wire cores such as SW-03HN25MDG, SW-03HN25MDGB. The same masteralloys are used at automatic argon-arc and electric-arc welding. As a means of flux, there is recommended grade AH-18.
Application
Manufacture of chemical welded devices: heat-exchangers, reactors, pipelines, equipment for mineral fertilizer synthesis. Manufacture of tanks that operate in solutions of phosphorus, 55% H2 SO4, spirit of verdigris and similar aggressive environments up to a temperature of 80 °C.
Welding electrodes are made of wire. They are used for joint of nozzle parts, pipe joints, repair of welding composition of nuclear reactors. Sheet is requested for convective coils as a means of two-layered hot-rolled corrosion-resistant sheets, installations for production of ethylene, ammonia, carbon disulfide, hydrogen and other chemical elements. This alloy well operates in temperature range of 700−960°C and pressure of up to 40 atm. In recent times, this steel is utilized in manufacture of branded utensils, pretties, luxury goods.
