WEAR RESISTANT CAST STEEL Russian patent published in 1998 - IPC

FIELD: ferrous metallurgy, more particularly machine building, industry. SUBSTANCE: alloying and modification of high-manganese steel with copper, vanadium, pyrodium carbonates comprising calcium, barium, strontium and aluminium make it possible to produce steels having high mechanical properties and wear resistance. Use of the claimed steel allows reducing the amount of metal used and increase efficiency of machines. Steel comprises (wt %): 0.9-1.4 carbon; 9.0-14.5 manganese; 0.30-0.65 silicon; 0.10-0.20 titanium; 0.020- 0.120 phosphorus; 0.005-0.05 sulfur; 0.03-0.55 zirconium; 0.8-1.2 copper; 0.20-0.30 vanadium; 0.005-0.015 calcium; 0.001-0.005 barium; 0.05-0.20 strontium; 0.01-0.14 aluminium; and the iron balance. EFFECT: improved properties of cast iron. 2 tbl
