WEAR-RESISTANT CAST IRON Russian patent published in 2005 - IPC

FIELD: ferrous metallurgy; production of the wear-resistant cast irons for use in the shock - abrasive wear conditions.

SUBSTANCE: the invention is pertaining to the field of ferrous metallurgy, in particular, to production of the wear-resistant cast irons for use in the shock - abrasive wear conditions. The wear-resistant cast iron contains (in mass %): carbon - 3.6-4.2; silicon - 2.2-3.2; manganese - 4.5-12.0; chromium - 2.7-4.3; copper - 0.25-1.2; titanium - 0.15-0,65; molybdenum - 0.5-1.5; niobium - 2.5-4.5; calcium - 0.005-0.01; iron - the rest. The technical effect is increased shock - abrasive wear-resistance of the cast iron.

EFFECT: the invention ensures an increased shock - abrasive wear-resistance of the cast iron.
