Application: tool blanks.
Advantages: the use of the technology of remelting of waste of tool production including modification and control of crystallization conditions for the formation of dispersed structure and make tools of high performance properties provides: the savings of the alloying elements; reducing the complexity and energy consumption; increase of operational stability by 1.5–2.2 times; the modification during melting; regulation of speed of crystallization; the use of precise casting techniques; ability to use as charge materials scrap, shavings, metal-abrasive sludge.
Key features: hardness up to 64–67 HRC; heat resistant up to 60–64; impact viscosity, kJ/m2 100–300; the metal utilization factor 0.85–0.9; wear resistance is 1.3-1.5 times higher compared to wear rolled materials.
Developed: Research Laboratory of Material Science and Foundry Technology, Dr. Fyodor Rudnitskiy, PhD (Cand. Techn.).
