Spheroidal Graphite Cast Iron
Ductile iron, also called ductile cast iron, spheroidal graphite iron, or nodular cast iron. While most varieties of cast iron are brittle, ductile iron is much more flexible and elastic, due to its nodular graphite inclusions.
Compare with Iron and Steel
From the carbon content of material, we can divide iron and steel. Cast irons typically contain 2-4 wt% of carbon with a high silicon concentrations and a greater concentration of impurities than steels.
Fe - C Curve
Iron (Fe) is not a high-purity metal commercially but contains other chemical elements which have a large effect on its physical and mechanical properties. The amount and distribution of these elements are dependent upon the method of manufacture. The most important commercial forms of iron are listed below.Pig iron is the product of the blast furnace and is made by the reduction of iron ore. Read more
Fastener Products
Fasteners are manufactured in a wide range of materials from common steel to titanium, plastic and other exotic materials. Many materials are further separated into different grades to describe specific alloy mixtures, hardening processes, etc. In addition, some materials are available with a variety of coatings or plating to enhance the corrosion resistance, or appearance of the fastener.
Fastener material can be important when choosing a fastener due to differences between materials in strength, brittleness, corrosion resistance, galvanic corrosion properties, and of course cost. Read more
Iron Comparison- Gray Iron and Ductile Iron
Gray Iron,
Gray iron or grey iron was the original “cast iron”. It is an alloy of carbon, silicon, and iron, containing from 1.7 to 4.5% C and 1 to 3% Si. It is relatively easy and inexpensive to make. Compared to the more modern engineered irons, gray iron has a lower tensile strength and lower ductility. Read more
Factors that influence product development
Product Analysis is the process of identifying, looking at or disassembling a product and identifying its main features. The aim is to understand more about a product and improve it in the future. Many factors influence the development of a product, some are listed below. Read more
