FERROUS METALS
Properties and Uses
Ferrous metals are alloys containing iron, most are magnetic, though some are only weakly so. The name Ferris comes from the Latin word Iron “Ferrum”.This bike is made of different ferrous metals the muffler is low-carbon steel, the Chains medium carbon steel and the springs are high carbon steel, the brake disc is cast iron the plastic hydraulic lines are protected by braided stainless steel and the fork chrome moly and some of the tools used for making this bike would have been tungsten alloy we are going to look at these different steels and see why they are used for different jobs. In the stone age it took a week to cut down a tree. With the discovery iron a steel X did the job in one hour. Iron had a tremendous impact on lifestyle and food production it was one of the most important changes for mankind today iron is the backbone of the world with built. It is strong plentiful and cheap Iron comes from iron-ore such as hematite, which is similar to rust, it is a combination of iron and oxygen. The oxygen is removed by heating the ore with carbon from coke the carbon removes the oxygen leaving iron but there is still some carbon left and this affects the properties of the iron so the carbon content has to be adjust carefully in a second furnace oxygen is blown through the molten iron the oxygen burns up carbon allowing steelmakers to adjust the amount of carbon. iron and carbon are known as steel.
CARBON CONTENT
The carbon content affects the properties.
We have
Pure Iron
Low Carbon Steel(mild steel)
Medium Carbon Steel
High Carbon Steel
Cast Iron
The low-carbon Steel is soft and easily Scratched the High-Carbon is much harder so High-Carbon Steel can cut Low-Carbon Steel
