The following types of materials are usually the most ductile
The percentage of carbon in pig iron varies from
Pig iron contains at least 92% Fe and has a very high carbon content, typically 3.5 - 4.5%.
Sulphur in pig iron tends to make it
Presence of sulfur tends to make iron hard and produces unsound castings. Wrought iron and steel produced from iron containing sulfur makes wrought iron and steel to be brittle when heated
Hardness of steel depends on
Depending on the temperature and composition of the steel, it can be hardened or softened.
To make steel harder, it must be heated to very high temperatures.
The final result of exactly how hard the steel becomes depends on the amount of carbon present in the metal.
Corrosion resistance of steel is increased by addition of
Eutectoid steel contains following percentage of carbon
Solder is an alloy consisting of
Actuallly there were two types of solder tin-lead alloy and tin copper alloy.Due restrictions in several countries only tin-copper solder is in use now.
Which of the following parameters is/are false for steel?
