Description Steelun of 15ХМФА Alloy structural steel:

15ХМФА steel is used: for the manufacture of seamless hot-deformed pipes with improved corrosion and cold-resistance (article 15ХМФА), with an outer diameter from 60 to 426 mm, strength class not less than K54, infield pipelines, transporting products of oil wells (high-pressure conduits at a pressure of 24.0 MPa).

Note

Structural alloy steel of high corrosion resistance and cold-resistance.

According to TU 1317-006.1-593377520-2003 the chemical composition is given for steel grade 15ХМФА. The mass fraction of hydrogen in the steel in the metal of the pipe should not exceed 1.0 ppm (2.0 ppm in the ladle sample, niobium and titanium can be added from the calculation of the mass fraction to 0.030% and 0.010%, respectively.) In the deoxidized steel for the globularization of sulfide inclusions enter calcium (silicocalcium) or cerium from the calculation of the mass fraction of 0.050%.
