Steel grade KhN62VMYUT-bd (old name - EP708-bd) is a grade of heat resistant steel based on nickel and chromium of stable austenitic class, which does not change the structure when cooling in the air after heat treatment. The base of the alloy is nickel, which is about 62% of the total mass. The alloy is alloyed with chromium, tungsten, molybdenum, titanium and aluminum. The most popular semi-finished products are wires, rods and tubes. They are topical in the power engineering industry (mechanical engineering sector that manufactures machinery and equipment for the power industry), the aviation and rocket and space industries. They can withstand a variety of mechanical stresses at very high temperatures of at least 600 °C,

General characteristics

Alloys designed to withstand extreme heat typically fall into the following groups: 1) heat resistant steels - work in loaded condition for a long time at t° up to 600 °C; 2) heat resistant, which have sufficient resistance to work in loaded condition for3) heat-resistant (scale-resistant) steels - they operate in low-loaded and unloaded state at temperatures above 550 °C, they are resistant to chemical attack by the coating in the gas environment. Under the load are understood several loading schemes: static tensile, torsional or bending load, thermal load, which depends on the temperature changes, variable dynamic load with different amplitude and frequency, the dynamic effect of gas velocity flows on the coating.

Application

Pipe grade CHN62VMYUT-vd used in facilities that operate under high pressure in the atmosphere of industrial gases. It is in demand in systems of water and gas drainage, is used for the construction of heat exchange systems. It is used in mechanical engineering and food industry, it is actively used in the manufacture of gas turbine blades. Round in terms of accuracy of rolling is divided into: standard and high accuracy classes (calibrated type). It is used in industrial construction, industrial engineering and machine tool construction, in the production of space equipment. Circles, made of such steel is characterized by plasticity and is easily welded with manual arc welding, so it is possible to quickly build steel structures.
