WitrynaThe iron manufactured in Blast Furnaces contain about 3 – 4 % of Carbon and smaller quantities of many other impurities such as sulphur, Silicon, etc. This is called Pig Iron. It is a hard but brittle metal and the impurities severely hamper its strength. WitrynaCast iron with 1–3% Ni are used for pump houses, water boxes and other component for service. Gray cast iron has a greater susceptibility to pitting than malleable cast iron. The pitting factor of cast iron is shown in Table 9.15 [32]. Pitting factor is represented as: Deepest pit depth/Average corrosion rate.

WitrynaThe iron that comes straight out of the blast furnace is called pig iron, and it tends to be very brittle because it contains 2 % – 5 % carbon and other types of impurities. Some of the pig iron is placed into molds to make what is known as cast iron. Cast iron is primarily used to make pans, drain covers, engine blocks, and fences.

WitrynaIn materials engineering, cast irons are a class of ferrous alloys with carbon contents above 2.14 wt%. Typically, cast irons contain from 2.14 wt% to 4.0 wt% carbon and anywhere from 0.5 wt% to 3 wt% of silicon. Iron alloys with lower carbon content are known as steel.
