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.
Thermoplastic-sheathed cable (TPS) consists of an outer sheath of polyvinyl chloride (PVC) insulation (the thermoplastic element) covering a core of one or more conductors of annealed copper.It is the most commonly used type of wiring for residential and light commercial construction in developed countries.t is incorrect to use Romex to refer to NM cable generically, as the Romex name is a trademarked brand of the Southwire Company. In modern products, the color of the NM cable sheath (or jacket) indicates either the gauge of the current carrying conductors within it, or special properties of the sheathing itself.
