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.

Note

Ledeburite steel of carbide class.
Highly wear-resistant steel with through hardenability in sections up to 150 mm.

Fe is the basis.
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.
