Wootz steel (According to traditional history wootz steel originated in India before the birth of Christ.: Wootz steel, also known as Seric steel, is a crucible steel characterized by a pattern of bands and high carbon content. These bands are formed by sheets of microscopic carbides within a tempered martensite or pearlite matrix in higher carbon steel, or by ferrite and pearlite banding in lower carbon steels. It was a pioneering steel alloy developed in India in the mid-1st millennium BCE and exported globally.  wikipedia.org Rus7) |
