Cast iron is an iron, carbon and silicon alloy that has been melted and poured into a mould to form a shape. The Chinese developed furnaces for making cast iron around 500 kg. These furnaces were hot enough to melt cast iron so that it could be poured into moulds to make many products including weapons, jewellery and cast iron cookware. The structure of cast iron, which is graphite flakes in a relatively pure iron matrix, has several useful properties. Firstly, the metal expands slightly on solidifying as the graphite precipitates, resulting in sharp, well defined castings. The graphite content also offers good corrosion resistance, particularly when compared to mild steel. Graphite acts as a lubricant, improving wear resistance. We have also achieved expertise in the manufacturing of diversified range of graded cast iron products that are designed in accordance with international parameters and specifications. The casting iron products are available in different sizes catering to the needs of our clients. One of the most distinct features that govern the sale of our |

products is the fact that our products are available at a very reasonable price. We are also fortunate to be blessed with most competent infrastructure and matured professionals that have successfully made us one of the authentic graded cast iron products manufacturers and one of the reliable suppliers from India. At Shri Durga Foundry every furnace heat is measured for carbon content by thermal analysis and the carbon content is adjusted to meet target levels. By carefully adjusting carbon content, our Foundry casts a wide range of gray iron as specified by Standard Specification for Gray Iron Castings. Since gray iron tensile strength and machinability is also controlled by the casting section thickness, the ability to adjust chemistry in small furnace heats is the key to short leadtime casting of small and large castings. We can melt several chemistry programs in a single day with our fast melt induction furnaces, shortening leadtimes for all our castings. |
