    Description

    06KH18N10T steel is used: for the manufacture of extremely thin-walled cold — and warm-deformed pipes for pipelines and structures of various purposes; welded equipment operating in environments of increased aggressiveness (the solutions of nitric, acetic acids, alkaline solutions and salts); structures to be welded by spot welding; wire woven grids with square cells of micron size, used for control and separation of materials by particle size, filtration of liquids, gases and other purposes.

    Note

    Steel corrosion resistant austenitic class.

    Macrostructure and pollution In the macrostructure of billets on the other 14-1-3935-85 in the state of delivery should be free of cracks, delamination, subcortical bubbles, curled up crusts, traces of shrinkage, inclusions, visible to the naked eye. Assessment of the quality of the macrostructure of a metal are also in points. For billets of metal of all kinds of smelting the Central porosity, point heterogeneity and phase separation in the square should not exceed a score of 1.0 for each species. For pipe billets with a diameter more than 110 mm of metal open arc and vacuum-induction melting Central porosity, point heterogeneity and phase separation in the square should not exceed a score of 2.0 for each species.
    Microstructure 06Х18Н10 steel has a lower content of ferrite phase than that of steel grade 08CR18NI10TI. In the tube blank on the other 14-1-3935-85 the content of the ferritic phase must not exceed 2.0 points, by agreement of the parties shall be allowed 2.5 points.
    Corrosion resistance Tubular billet on the other 14-1-3935-85 must withstand the test of intercrystalline corrosion.
