An Introduction to Nitriding - ASM International

An Introduction to Nitriding THE NITRIDING PROCESS, rst developed in the early 1900s, con-tinues to play an important role in many industrial applications. Along with the derivative nitrocarburizing process, nitriding often is used in the manufacture of aircraft, bearings, automotive components, textile machin-ery, and turbine generation Cast Iron - an overview ScienceDirect TopicsGraphitization is a form of attack characteristic of gray iron which considerably weakens the iron. Cast iron with 13% Ni are used for pump houses, water boxes and other component for service. Gray cast iron has a greater susceptibility to pitting than malleable cast iron. The pitting factor of cast iron is shown in Table 9.15 [32]. Pitting

Classification and Basic Metallurgy of Cast Iron[1

This article discusses the classification schemes for cast irons and describes the characteristics of major categories, including gray iron, white iron, ductile iron, compacted graphite iron, mottled iron, malleable iron, and austempered ductile iron. It also discusses some of the basic principles of cast iron metallurgy.

of the grey cast iron. The gate must introduce molten metal into the mould with minimum turbulence and must reduce turbulence in the runner regions. Though iron is not a dross forming substance, it is ferrous alloy with extreme melting temperatures and hence its velocity must be controlled with a greater care. Grey Cast Iron - an overview ScienceDirect TopicsGray iron is so named because its fracture has a gray appearance. It contains carbon in the form of flake graphite in a matrix that consists of ferrite, pearlite, or a mixture of the two. The fluidity of liquid gray iron, and its expansion during solidification due to the formation of graphite, has made this metal ideal for the economical production of shrinkage-free, intricate castings such as engine blocks.

Mistry MakeToolApr 25, 2020 · It is sometimes made of cast steel or malleable cast iron, but most are made ofcast iron. However, most heavy duty vises are 55,000 psi cast steel or 65,000 psi ductile iron. Some vises have a cast iron body but a steel channel bar. Cast iron is popular because it is typically 30,000 psi grey iron which is rigid, strong and inexpensive.

    Malleable Cast Iron - Properties and Uses

    Malleable iron starts as a white iron casting that is then heat treated for a day or two at about 950 °C (1,740 °F) and then cooled over a day or two. As a result, the carbon in iron carbide transforms into graphite nodules surrounded by a ferrite or pearlite matrix, depending on cooling rate. SinterCast AB Compacted Graphite IronCompacted Graphite Iron. Cast irons are differentiated by the shape of the graphite particles. Grey cast iron is characterized by randomly oriented graphite flakes, while the graphite in ductile iron exists as individual spheres. The graphite particles in CGI are randomly oriented and elongated as in grey iron, but they are shorter, thicker and

    May 02, 2018 · Introduction. Ductile iron possesses the processing advantages of grey iron, such as low melting point, good fluidity, castability and machinability, and engineering advantages of steel, including high strength, ductility and wear resistance. Achieving the desired quality consistently at low cost in a production foundry is, however, still a What Is Galvanized Iron? - Monroe EngineeringJan 30, 2020 · Oxidation will cause the iron to rust and corrode. How Iron Is Galvanized. There are several methods used to create galvanized iron, one of which is the hop-dip method. The hot-dip method involves the deposition of zinc onto the surface of iron by dipping the iron is molten, hot zinc. Its the most common method used to create galvanized iron.

These are iron-carbon alloys (and a form of cast iron) with carbon contents in excess of 2%, generally in the range 2 to 4% with the addition of about 1% silicon. They differ from steels in that the carbon present exceeds the solubility limit of 1.7%. This carbon is present in the form of austenite while the excess
