FIELD: metallurgy.
SUBSTANCE: grey bearing cast iron can be used for cast anti-friction items with upgraded mechanical and operational properties for sleeves of engines and mechanisms of friction. Iron contains, wt %: carbon 3.0-3.4; silicon 2.0-2.4; manganese 0.6-0.8; phosphorus 0.1-0.2; sulphur 0.02-0.12; chromium 0.4-0.6; nickel 0.2-0.5; copper 0.4-0.8; aluminium 0.03-0.7; barium 0.008-0.025; nitrogen 0.002-0.012; titanium 0.03-0.08; iron - the rest.
EFFECT: iron possesses high ultimate bending strength and low tendency to cracking in cast items.
