Answer

Iron in the form of castings or forgings can be brittle. Iron forms a metallic crystal structure when changing phase from liquid to solid, and the crystal structure can be subject to brittle failure. If the load or force on something that is cast iron is great enough and applied in the right (wrong) way, it will fail due to this brittle fracture. Generally speaking, things made of iron are engineered and manufactured to provide sufficient strength to resist brittle fracture, but there are a number of things that can cause iron to become more brittle. Temperature is one. If it gets cold enough, an iron part could fail when stress is applied to it in a situation where it would not fail at "room temperature" or above. Iron, or any metal has a certain amount of inherent brittleness (because the metal forms crystal structures when solidifying). And iron can be made more brittle by (decreased) temperature, fatigue, hydrogen, and the list goes on. The volume of literature on the subject is nothing short of staggering. The failure of metal structures, a subset of the science of Metallurgy, is a hugely broad discipline, and it continues to hold up questions that have not been answered.

The iron produced by a blast furnace, called pig iron, is not very useful. It is about 96% iron and contains impurities, mainly of carbon. This makes pig iron very brittle. However, we can treat the iron from the blast furnace to remove some of the carbon.

Iron from a blast furnace is called pig iron and it contains other elements to it. This makes it soft and cannot be used in many things like making a bridge so its content is removed. Then it is added with different elements in different quantities to make it stronger for different uses eg: stainless steel by adding chromium, manganese and nickel or other elements.

The iron that comes out the blast furnace is called cast iron. It is about 96% iron and 4% carbon, and this carbon impurity makes it too brittle to use in constructure. Pure iron, however, is too soft, all pure metals are. That's why we make steel. Three of the most common steels are:

Medium steel - 0.25% carbon

High carbon steel - 0.75% carbon

Stainless steel - a mixture of iron, chromium and nickel. Hope this helps :-)

Because it has not been treated to harden it up there is a process called hardening that involves carbon that strengthens it up.

What is the difference between pig iron and cast iron?

Pig iron is cast iron with a very high carbon content: 4% by weight or more. Cast iron has at least 2% carbon by weight. Less than that, and it's steel. Cast iron and pig iron are not called steel, despite being iron carbides, because they lack the structural strength of steel and are extremely brittle. In terms of the microstructure, cast iron and pig iron contain no cementite, austenite, or martensite. Historically, "pig iron" refers to cast iron made by a particular process: the high-carbon molten iron made in a blast furnace was poured into moulds made of sand, which had a particular shape. Narrow trenches would run down the edge of the mould, and then branching off of them there would be the actual ingots. The whole setup looked to the ironworkers like a sow suckling piglets, so the product became known as pig iron.


What is pig iron?

Pig iron is the intermediate product of smelting iron ore with a high-carbon fuel such as coke, usually with limestone as a flux. Charcoal andanthracite have also been used as fuel. Pig iron has a very high carbon content, typically 3.5-4.5%, which makes it very brittle and not useful directly as a material except for limited applications.The traditional shape of the molds used for these ingots was a branching structure formed in sand, with many individual ingots at right angles to a central channel or runner. Such a configuration is similar in appearance to a litter of piglets suckling on a sow.When the metal had cooled and hardened, the smaller ingots (the pigs) were simply broken from the much thinner runner (the sow), hence the name pig iron. As pig iron is intended for remelting, the uneven size of the ingots and inclusion of small amounts of sand was insignificant compared to the ease of casting and of handling.Other Answers:Pig iron is called pig iron because due to it shape and molds. When the iron come out from its mold due to it contain % of carbon and it look black pigs, when it come out of it mold it look like pigs standing in a group so it is called pig iron.____________________Definition of Pig Iron: The term was derived from the method of casting the bars of iron in depressions or moulds formed in the sand floor adjacent to a furnace. These were connected to a runner (known as a sow) and when filled with metal the runner and the numerous smaller moulds were supposed to resemble a litter of suckling pigs, hence the term pig iron.____________________Wrought Iron is Pig Iron.____________________It was Abraham Darby II (1711-63) who improved the quality of coke-smelted pig iron and made it suitable for forging into wrought iron. Wrought iron was the result of forging pig iron by continued hammering and reheating in order to produce a material which was supple enough to be made into tools and implements.iron ore.___________________

Why is pig iron not useful?

Pig Iron is a very low grade of Iron, often mixed with scrap metals in the smelting process, that is much less sturdy that normal steel. Making it useless for most tasks one would use Steel for.

Which is purer wrought or pig iron?

Pig iron is generally an intermediate product of the wrought iron and steel making process. Pig iron is virtually useless due to the very high impurity content. "Pure" is a strange quantification of the comparison between pig iron and wrought iron. Pig iron is pure pig iron and wrought iron is pure wrought iron if there is a "standard" for the respective materials. I'm guessing that the answer you want is that wrought iron is "more pure."
