Can anyone please define each of and differentiate between the following -- pig iron- cast iron- wrought iron- steelI have checked the books and the internet, but each new page just presents a whole new definition. I would be very grateful if you could help.Thanks!
i just learnt this last year but i forgotten some of them. For cast iron, there is a higher carbon content as well as silicon. The addition of silicon causes the carbon to diffuse out of the carbide to form graphite. Cast iron is generally brittle hence is usually casted into different shapes. Hence the name. For steel, the carbon content is lower. Steel is generally stronger and more ductile but also more expensive than cast iron. There are many different types of steel like alloy steel, high carbon steel, low carbon steel and stainless steel. For wrought iron, i can't exactly remember but i think that wrought iron has higher ductility and can be formed by forging pig iron i thought is crude form of iron. not sure though
replace the battery/when they get weak the alarm starts to react
You enter the wonderful world of metallurgy here. Pig, cast and wrought iron refers to the way the iron is purified and formed as a product. Steel is a generic term for iron-carbon mixtures (a few percent carbon at most) that have mechanical properties superior to iron. Stainless steels have elements such as nickel and cobalt added, which forms a metal that does not rust easily, and has even superior mechanical properties.
