The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things - nails, wire, car bodies, ship building, girders and bridges amongst others. High carbon steel: High carbon steel contains up to about 1.5% of carbon.

Types of Cast Iron. 1. Gray Cast Iron: ( Types of Cast Iron ) The most common type of cast iron is known to be gray cast iron which features a graphite microstructure that consists of various small fractures. It is named in such a way as the presence of these small fractures is responsible for creating the appearance of a gray color.

While ashwagandha may have potential as an iron supplement, it is not typically considered a rich source of this vital nutrient. There are many other foods that are much higher in iron, including red meat, poultry, fish, legumes, and leafy greens. Additionally, many foods are fortified with iron, including breakfast cereals, pasta, and bread.
White cast iron shows a white fracture and have the following relative compositions: It consists of Carbon – 1.75 to 2.3%, Silicon – 0.85 to 1.2%, Manganese – 0.10 to 0.40%, Phosphorus – 0.05 to 0.20%, Sulphur – 0.12 to 0.35%. Because the carbon is in the form of cementite in metals the white color occurs.
