Cast iron products under consideration are manhole covers, Cast iron pipe, Malleable iron fittings, and Grey iron castings. Cast iron, an alloy of iron that contains 2 to 4 percent carbon, along with varying amounts of silicon (up to 3 percent) and manganese and traces of impurities such as sulfur and phosphorus. Cast iron is highly preferred for its casting ability into complex shapes when molten and its low cost. It is the favoured choice over steel because of its compressive strength, excellent vibration dampening, corrosion resistance, wear-resistance and ease of machining capability. Different types of cast irons are produced using different process and heat treatment techniques.
