Jun 22, · High-chromium (25 – 35% Cr) cast irons are recommended during operation in oxidizing acids, especially in nitric acid. They exhibit good corrosion resistance in sulfuric acid of any concentration at temperatures up to 80°C, and in phosphoric acid at a concentration ≤ 60% up to the boiling temperature and with a concentration of ≤ 85% up to 80°C.

High-chromium cast irons are widely needed by several industrial areas where wear is the dominant environment. They are used in mining, cement- and steel-making plants, and many others. Their microstructure consists of netted eutectic carbides embedded in an austenitic or martensitic matrix. The wear behaviour is mainly controlled by the carbides shape and also matrix type. Several scientific

Jul 23, · High-chromium cast iron (HCCI) has been widely used for wear-affected equipment and operating conditions, such as wear-resistant lining board, crusher jaw plate, mining and mineral machinery processing, and oil sands handling [ 3, 4, 5, 6 ]. The good wear resistance of HCCI is due to the lots of (Fe,Cr) 7 C 3 carbides [ 7, 8, 9 ].
