Metallurgy - Casting Britannica
If the molten iron is chill cast (i.e., rapidly cooled), it will form a “white” iron containing about 60 percent cementite, or iron carbide. This material is hard and wear-resistant, but it has no ductility at all. These cast irons are usually given a heat treatment to improve

Gray iron metallurgy Britannica
2021-5-20 cast iron. cast iron is either so-called gray iron or white iron, the colours shown by fracture. Gray iron contains more silicon and is less hard and more machinable than is white iron. Both are brittle, but a malleable cast iron produced by a prolonged heat treatment was developed in France in.

Blackheart malleable iron metallurgy Britannica
2021-5-20 cast iron. In iron processing: White iron. Blackheart malleable iron, on the other hand, is made by annealing white iron in a neutral atmosphere, again at a temperature of 900° C. In this process, cementite is decomposed to form rosette-shaped graphite nodules, which are less embrittling than flakes.

Whiteheart malleable iron metallurgy Britannica
cast iron. In iron processing: White iron. Whiteheart malleable iron is made by using an oxidizing atmosphere to remove carbon from the surface of white iron castings heated to a temperature of 900° C (1,650° F). Blackheart malleable iron, on the other hand, is made by annealing white iron in a neutral.

Types of Cast Iron. Iron that is poured into a mold of sand or other material is called cast iron. Pig iron is a crude form of cast iron poured from the blast furnace. There are five major types of cast iron: white, malleable, gray, ductile, and high alloy. In general they contain 2 percent or more of carbon plus silicon.

Iron and Steel - 1911 Encyclopedia Britannica
2021-1-19 3. Definitions. Wrought iron is slag-bearing malleable iron, containing so little carbon (0.30% or less), or its equivalent, that it does not harden greatly when cooled suddenly.. Steel is iron which is malleable at least in some one range of temperature, and also is either (a) cast into an initially malleable mass, or (b) is capable of hardening greatly by sudden cooling, or (c) is both so ...

2019-4-24 The development of iron casting is based on a long history of innovation – just like the history of The C.A. Lawton Co. The first article of this series traced the history of iron casting from its earliest expressions, thousands of years ago, to Europe in the early 1800s. In this article, we follow the growth of iron castings from the 1800s through the 1950s – the New Iron Age.
