|Designation GOST Cyrillic||Х9ВМФ|
|Designation GOST Latin||X9BMF|
|By chemical elements||Cr9WMoV|
Х9ВМФ steel is used: for the manufacture of parts gaskets drill bits (between the crown and tungsten carbide tipped); mnogovolnovye work rolls of the mills for rolling thin and the thinnest of sheet metal working at temperatures of +800 °C.
Ledeburite steel of carbide class.
Highly wear-resistant steel with through hardenability in sections up to 150 mm.
|Bars and shapes||В32||TU 14-19-40-88|
According to TU 14-19-40-88 the chemical composition is presented for steel grade X9VMF-III. The steel is introduced by calculation of titanium by 0.15%, cerium by 0.05%, niobium by 0.15%, and chemical analysis is not determined. Other requirements for the chemical composition of steel, allowable deviations from the standards of chemical composition and residual contents of elements - in accordance with GOST 5950.
|Macrostructure and pollution||The quality of the macrostructure of bars on the other 14-19-40-88 must comply with the requirements of GOST 5950, the Central porosity, point heterogeneity in the macrostructure should not exceed 1 point for each type.|
|Particularities of production of goods||On the other 14-19-40-88 forged rods are supplied in the annealed state (after annealing or high tempering). The hardness of the steel in the delivery state should be no more than 255 HB (indentation diameter not less than 3.8 mm).|
