What is the difference between the pig iron, wrought iron and steel?
Iron cast iron wrought iron division refers to: wrought iron through a variety of after heating their carbon content decreases, the hardness increases. The difference is that the number of pig iron and wrought iron with carbon content of pig iron with high carbon content, wrought iron has a lower carbon content. The carbon content of steel between iron and wrought iron.
Toughened glass with high impact strength (4 higher than ordinary flat glass - 5 times), flexural strength (5 times higher than ordinary flat glass), good thermal stability and smooth, transparent, cutting and other characteristics. In the case of strong impact damage, fine granular debris is scattered, no sharp edges, so also called safety glass.It has almost the same hardness as steel and has many uses. Its hardness makes it widely used and can be seen everywhere
Steel toughness, mainly used in tension, and the main iron carbon than steel, toughness is not good, it is generally used for pressure. Tempered glass refers to the other trace elements added in the processing of glass makes it have the same properties as steel, hence the name.
