CORROSION-RESISTANT CAST IRON WITH SPHERICAL GRAPHITE

摘要

FIELD: metallurgy. ^ SUBSTANCE: cast iron can be used for manufacture of working elements of sludge and sand pumps and hydraulic machines, which pump abrasive pulps, mixtures and suspensions. Corrosion-resistant cast iron with spherical graphite contains the following, wt %: carbon 3.2-4.0; silica 1.5-3.0; manganese 0.8-3.5; chrome 7.0-10.0; nickel 2.0-4.0; boron 0.2-0.4; vanadium 0.4-1.0; molybdenum 0.1-0.5; titanium 0.1-0.4; aluminium 0.05-0.2; cerium 0.03-0.2; magnesium 0.02-0.1; calcium 0.05-0.2; iron- the rest. ^ EFFECT: cast iron has increased resistance to impact of corrosion abrasive media. ^ 2 tbl
