CAST WEAR-RESISTANT STEEL FOR LARGE PARTS OF MINING AND SMELTING PROCESSES Russian patent published in 2006 - IPC C22C38/12 

FIELD: metallurgy; making steel for large items of mining and smelting processes under high shock loading and abrasive wear, for example cone-type crushers for coarse crushing and cone-type funnels of filling apparatus.

SUBSTANCE: proposed cast wear-resistant steel contains the following components, mass-%: carbon, 0.80-0.95; silicon, 0.20-0.40; manganese, 8.50-10.0; nickel, 0.50-0.85; tungsten, 0.10-0.30; nitrogen, 0.025-0.045; vanadium, 0.05-0.10; phosphorus, no more than 0.070; sulfur, no more than 0.012, the remainder being iron. Steel may also contain molybdenum in the amount of 0.10-0.30 mass-%.

EFFECT: enhanced wear resistance of large items made from proposed steel.
