Wootz steel is a steel characterized by a pattern of bands or sheets of micro carbides within a tempered martensite or pearlite matrix. It is the pioneering steel alloy matrix developed in South India in the sixth century BC and exported globally.It was also known in the ancient world as Seric Iron.ral tradition in India maintains that a small piece of either white or black hematite (or old wootz) had to be included in each melt, and that a minimum of these elements must be present in the steel for the proper segregation of the micro carbides to take place.
Magnetite is a ferromagnetic mineral that is in the iron oxide family. It is formed of one part wustite and one part hematite. Wustite is itself an iron oxide mineral that is found in meteorites as well as in native iron. Hematite is also a form of iron oxide and is commonly mined as the principal ore of man-made iron.
