A Brief Note on the Properties of Grey Cast Iron

A Brief Note on the Properties of Grey Cast Iron

Grey Cast Iron, which is generally an alloy of Carbon and steel, is manufactured by re-melting pig iron. There are appreciable amount of Silicon, Manganese, Phosphorus and Sulphur in it. Grey Cast Iron is popular because they are low cast and can make complex structures.  Let’s see what makes Grey Cast Iron the most popular of all widely used alloys. The following is a list of some of its properties:

High compressive Strength:
The strength of any metal or alloy is defined by its endurance to withstand compressive forces or agents. Grey Cast Iron has a greater compressive strength and therefore, it is widely used in construction to make columns and posts of buildings. Besides, their comparative strength is comparable to that of some mild steels.

Tensile Strength:
Different Grey Cast Iron has different tensile strength ranging from 5 tonnes per square inch to 19 tonnes per square, but on an average their strength is 7 tons per square inch. However, addition of Vanadium can enhance the strength of Grey Cast Iron.

Resistance to Deformation:
Grey Cast Iron is highly deformation-resistant and offers a rigid frame. But, if there is a problem related to construction, then even Grey Cast Iron made structure can tend to breakdown.

Low Melting Point:
Grey Cast Iron possess low melting point in the range of 1140 ºC to 1200 ºC.

Resistance to Oxidation:
Grey Cast Iron is extremely rust-resistant. Rust is formed by the reaction of Iron and oxygen. It is the recommended method to eliminate the effects of corrosion.

Considering the physical and chemical properties of the Grey Cast Iron mentioned above, it is used in a number of industrial applications. VR Foundries supply uncontaminated Grey Cast Iron that is applicable for the construction of sturdy products and in some residential fields. So, learning about properties of Grey Cast Iron from an application perspective is very important.
