Foundries sprung up throughout the east, casting saddlery hardware, carriage parts, and agricultural implements. Like other investment castings, there are also different producing methods of iron castings. Malleable iron founding is one of the oldest national industries, begun in the United States by Seth Boyden (1788-1870) in the 1820s. The favourable influence of the addition of tellurium into malleable cast iron molten metal on the tested properties after annealing as well as an percentation of graphite structure from 2. Clark, who along with his brother-in-law Abel Buell brought the foundry to Westmoreland, ran the ironworks until 1871 and was the first of six generations who still own and manage it. The firm was founded as Oakhill Malleable Iron Company in 1833 and was established under its present name in Westmoreland in 1850. The history of this foundry, which was the oldest malleable iron company in continuous operation in the United States for many years, was inseparable from that of the small town of Westmoreland, where neighbors and workers kept time by the foundry bell. Malleable iron is a cast ferrous metal that is initially produced as white cast iron and is then heat treated to convert the carbon-containing phase from iron carbide to a nodular form of graphite called temper carbon.
