Number 937523 V.N.Gridnev, V.G. Gavriljuk, A.V.Kozlov, F.I.Mashlenko, Yu.Ya.Meshkov, K.V.Mikhailov, N.S.Mordyuk Bulletin "Discoveries, Inventions", 1982, ¹ 23	Examples of practical use of technologies developed in the department   Austenitic steel for armouring cables of maritime communications (tensile strength 1950-2000 MPa) Austenitic stainless steel for high-strength non-magnetic pipes for directional orientation systems of  oil drilling (yield strength of 700MPa)   Austenitic stainless steel for corrosion-resistant springs and syringes. Stainless martensitic steel for dental instruments Formation mechanism of coal methane and method of its production of coal The correlation between the presence of iron compounds and methane content in coal beds is determined. The result is confirmed by modelling of methane generation with the mechanical mixture of reactor graphite and iron compounds.
