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 ...

15 kwi 2016 · Cast Iron. 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.
30 wrz 2021 · The document provides information on cast iron, including its history, manufacture, composition, types, properties, uses, production/processing, and future applications.
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,
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.
The document discusses various types of alloy cast irons and their properties and applications. It focuses on Ni-hard alloys which contain 4% nickel and 2% chromium (Ni-hard 1 and 2) or 9% chromium, 6% nickel, and 2% silicon (Ni-hard 4).
Cast irons are iron based alloys containing more than 2% carbon, 1 to 3% silicon and up to 1% manganese. As cast irons are relatively inexpensive, very easily cast into complex shapes and readily machined, they are an important engineering and structural group of materials.
