Purpose of the development: The technology is designed for engineering products (rolls, bowls, plates of armor protection) of high-chromium iron-carbon alloys with carbon content of 3-3.5% chromium - 12-21,5% of the nanostructured matrix (plate thickness and bainite phase is 20 -30 nm) due to the implementation of the bainite transformation during cooling products with cast heat

Recommended application field: Metallurgy, machinery

Advantages over analogues: The technology provides: - Reducing the consumption of expensive alloying elements: chromium - 24% nickel - 50%, titanium, vanadium and tungsten - 100%; increase in wear resistance of 1.5-2 times; - Improving the heat resistance of 1.5 times; - Increasing component life by 2-3 times.

The development stage readiness: Ready for application
