Composition of White Cast Iron. With a lower silicon content (containing less than 1.0 wt% Si – graphitizing agent) and faster cooling rate, the carbon in white cast iron precipitates out of the melt as the metastable phase cementite, Fe3C, rather than graphite. In the figure, there is the iron–iron carbide (Fe–Fe3C) phase diagram.
Iron is the fourth most abundant element, by mass, in the Earth's crust. The core of the Earth is thought to be largely composed of iron with nickel and sulfur. The most common iron-containing ore is haematite, but iron is found widely distributed in other minerals such as magnetite and …

In this article we will discuss about:- 1. Introduction to Cast Irons 2. Composition and Cooling Rate of Cast Irons 3. Comparison of Properties 4. Science of Development of Microstructures. Introduction to Cast Irons: Cast irons are iron-carbon (and silicon) alloys having carbon or carbon equivalent value, more than 2% (actually it is 2.1 1%), i.e., more …
Beginners should always choose irons described as "game improvement" or "super game improvement," as these provide the golfer the most help. Set Composition A typical, off-the-shelf set of irons will include a 3-iron through pitching wedge (advertised as "3-PW"), 8 clubs total.

Introduction. Alloy steels contain a wide range of steels whose compositions exceed the limitations of C, Mo, Cr, Va, Mn, Ni, Si, and B fixed for carbon steels. These steels are more responsive to mechanical and heat treatments than carbon steels. AISI 8620 alloy steel is a common, carburizing alloy steel. This alloy steel is flexible during ...
Red meat, egg yolk, carrots, fruit, whole wheat, and green vegetables contribute most of the 10–20 milligrams of iron …
12.5 Iron And Steel Production ... A typical BOF cycle consists of the scrap charge, hot metal charge, oxygen blow (refining) period, testing for temperature and chemical composition of the steel, alloy additions and reblows (if necessary), tapping, and slagging. The full furnace cycle typically ranges from 25 to 45 minutes.
The four basic types of cast iron are white iron, gray iron, malleable iron, and ductile iron. In addition to these basic types, there are other specific forms of cast iron to which special names have been applied, such as chilled iron, alloy iron, and compacted graphite cast iron. Gray Cast Iron

The main component of the cast iron structure is ferrite, which has very low strength. The strength of cast iron increases with growth in the portions of pearlite, bainite, and …
Composition of Cast Irons: (a) Carbon: ADVERTISEMENTS: As the carbon content increases, the melting point (as compared to steels) is lowered to between 1200° to 1140°C, and thus, carbon acts as a graphitiser. But, more the graphite formed, lower are the mechanical properties. (b) Silicon (0.5-3.0%):

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.
