The earliest cast iron artifacts, found in China, date back to 513 BC. The Chinese of this time had developed furnaces hot enough to melt iron. Using this process, they were able to pour molten iron into a cast or mold to make many products, including cast iron cookware. In 1708 Abraham Darby invented a process for making cast iron in large industrial quantities, suitable for making big structures such as bridges, heavy machinery, etc. His invention helped to start the Industrial Revolution in Europe.

It depends on what you want to use it for. On the Moh's scale, steel is somewhere between 4 and 4.5, whereas iron is between 6 and 7. In swords, both iron and steel kinds have appeared, but steel is slightly better than iron due to its strength-to-weight ratio and its flexibility. Keep in mind, steel--unlike iron--is made of different metals to improve its strength. For piping, steel would be better (but not the first choice among other materials to use). Steel is also more resistant to rust, than iron, and the weldability of steel is better than iron.
Pig iron is the intermediate product of smelting iron ore with a high-carbon fuel such as coke, usually with limestone as a flux. Charcoal andanthracite have also been used as fuel. Pig iron has a very high carbon content, typically 3.5-4.5%, which makes it very brittle and not useful directly as a material except for limited applications.The traditional shape of the molds used for these ingots was a branching structure formed in sand, with many individual ingots at right angles to a central channel or runner. Such a configuration is similar in appearance to a litter of piglets suckling on a sow.When the metal had cooled and hardened, the smaller ingots (the pigs) were simply broken from the much thinner runner (the sow), hence the name pig iron. As pig iron is intended for remelting, the uneven size of the ingots and inclusion of small amounts of sand was insignificant compared to the ease of casting and of handling.Other Answers:Pig iron is called pig iron because due to it shape and molds. When the iron come out from its mold due to it contain % of carbon and it look black pigs, when it come out of it mold it look like pigs standing in a group so it is called pig iron.____________________Definition of Pig Iron: The term was derived from the method of casting the bars of iron in depressions or moulds formed in the sand floor adjacent to a furnace. These were connected to a runner (known as a sow) and when filled with metal the runner and the numerous smaller moulds were supposed to resemble a litter of suckling pigs, hence the term pig iron.____________________Wrought Iron is Pig Iron.____________________It was Abraham Darby II (1711-63) who improved the quality of coke-smelted pig iron and made it suitable for forging into wrought iron. Wrought iron was the result of forging pig iron by continued hammering and reheating in order to produce a material which was supple enough to be made into tools and implements.iron ore.___________________
Cast Iron does not rust or corrode as steel can

to produce less expensive, better-quality iron
Abraham Darby's experiments with coke as a fuel led him to develop a method for smelting iron ore using coke instead of charcoal. This discovery revolutionized the iron industry by making production faster, more efficient, and less expensive. It also played a key role in the Industrial Revolution.

The Iron Bridge near Telford in Shropshire, England, was designed by Thomas Farnolls Pritchard, and it was built by Abraham Darby III.
The first iron bridge was made in Coalbrookdale in Shropshire
He invented coke smelting. Coke is a fuel with few impurities and a high carbon content, usually made from coal. The carbon monoxide produced by its combustion reduces iron oxide (hematite) in the production of the iron product thus creating a better quality of iron.
Thomas Farnolls Pritchard, designed the world's first iron bridge and it was built by by Abraham Darby III.
The world's first cast iron bridge was built over the River Severn at Coalbrookdale in the year 1779.
Abraham Darby replaced charcoal with coke in iron melting in the early 18th century. Darby's use of coke in his furnace at Coalbrookdale revolutionized iron production by allowing for a more efficient and controlled process, leading to the growth of the industrial revolution.
