15 kwi 2016 · This document provides information on various types of cast iron: - White cast iron forms massive carbides when iron cools rapidly, making it very hard but brittle. It is used for abrasion resistance. - Grey cast iron contains flake graphite in a matrix, giving it good machinability and vibration damping. It is widely used for machine parts.
High-silicon cast irons represent the most universally corrosion- resistant alloys available at moderate cost. When silicon level exceeds 14.2%, high-silicon cast irons exhibit excellent corrosion resistance to H 2 SO 4 , HNO 3 , HCl,
25 mar 2016 · ALLOY CAST IRON: An alloy cast iron is one which contains a specially added element or elements in sufficient amount to produce a measurable modification in the physical or mechanical properties. Alloying elements are added to cast iron for special properties such as resistance to corrosion, heat, or wear, and to improve mechanical properties ...
8 lis 2021 · This document discusses different types of cast irons and their properties. It begins by explaining the composition of cast iron which contains more than 2% carbon along with alloying elements like silicon, sulfur, manganese, and phosphorus.
Cast iron is one of the oldest ferrous metals in commercial use. It is primarily composed of iron (Fe), carbon (C) and silicon (Si), but may also contain traces of sulfur (S), manganese (Mn) and phosphorus (P). It has a relatively high carbon content of 2% to 5%.
Fabrication of metals and alloys. Four basic manufacturing processes: Casting– to give a shape by pouring in liquid metal into a mold that holds the required shape, and letting harden the metal without external pressure. Forming– to give shape in solid state by applying pressure.
21 sie 2018 · There are three different high-alloy cast irons that are resistant to corrosion: high-silicon, high-chromium and high-nickel cast irons, depending on the alloying elements incorporated to the iron in substitutional solid solution.
