В составе сплава компоненты проявляют себя следующим образом. Марганец, рений, бор, хром обеспечивают повышенную твердость и износостойкость сплава. Титан улучшает металлическую основу сплава. Бор стабилизирует карбиды. Ванадий увеличивает прочность и вязкость сплава, препятствует образованию заусениц и трещин, образующихся при истирании.In the composition of the alloy, the components manifest themselves as follows. Manganese, rhenium, boron, chromium provide increased hardness and wear resistance of the alloy. Titanium improves the metal base of the alloy. Boron stabilizes carbides. Vanadium increases the strength and viscosity of the alloy, prevents the formation of burrs and cracks formed during abrasion.

Сплав выплавляют в электропечах и отливают в горячие (400-450°C) металлические формы, обмазанные огнеупорной глиной. Отливки отжигают при температуре 740-760°C.The alloy is smelted in electric furnaces and cast into hot (400-450 ° C) metal molds coated with refractory clay. Castings are annealed at a temperature of 740-760 ° C.
