HN73MBTJU (EI698) grade is high-alloyed heat-resisting steel. Except for substantial proportion of nickel (65,073 — 71,2%) and chrome (26−29%), there are also niobium (2,2%), titanium (<2,75%), molybdenum (<3,2%), iron (1%). Such components as carbon, phosphorus, sulfur, mangan and other are contained in a tenth and in one hundredth of percent. Alloying has to be done for increasing workable features (a heat-resistance, a resistance to aggressive environment). A superfluous alloying increases a cost of alloy. That is why it has to be done very economically.
Chemical composition of alloy
Smelt of a metal is done in open induction furnace. Rolling is done at a temperature of 1170 °C at the beginning, and at 800 °C in the end of process. After deformation, a steel should be cooled. According to a first pattern, there must be done a cooling in water, in oil, or in air. During a second pattern, a cooling is done with a help of water with further holding (3−4.5 hours). Pipes can be made of standard and increased accuracy. There are manufactured pipes of various thread types on customer’s request: for example with a cylindrical cut thread of different length or without thread at all. Bar, rod are made with a help of hot-rolling and design. It must be done for making an accurate outer diameter. Welding of HN73MBTJU grade is done with a help of electrodes KTI-762.
HN73MBTJU pipes can work under load at a temperature of about 650 °C for a long time. They are used in mechanical engineering, for manufacturing disks, runners. It is also used in industrial chemistry, petrochemical, paper-and-pulp industries. This steel is suitable for making gas-water conveyance pipes, which are used in industrial, civil building (f. e. in heat-exchange systems). Besides, there can be made connecting gangways and pipe fittings for tubes of stainless steel. In this case, seams must possess the same requirements toward heat resistance. It depends on utilised alloy, selection of welding materials, welding conditions, presence of heat treatment on completing a process.
