High-chromium irons have good mechanical properties, high hardness in a cast state, low fluctuation of hardness when properties change. High-chromium irons almost don't concede in fluidity to regular gray cast iron that allows using parts sufficiently difficult form directly after casting without the following machining.
high carbide content which forms along with austenite during solidication as a proeutectic or eutectic phase depending on alloy composition and partic ularly depending upon carbon and chromium content, high chromium irons h t w is a high chromium white cast iron that is used where high corrosion and abrasion resistance are
Due to the high content of chromium in the alloy, it is easy to form a film on the surface of the molten iron, so the liquid iron seems to have poor fluidity, but in fact, the fluidity is better. (3) The shrinkage of high chromium cast iron is similar to that of cast steel, and its linear shrinkage rate can be calculated as 1.8% to 2% on the ...
