Ductility and Strength are the two major characteristics of modern rebars. We at Hama Steel ensures these two characteristics by Nital Etching Test in which we get the rings of Martensite at outer surface, Ferrite+Pearlite at the core and Bainite in between, by stirring the precisely prepared surface of rebar in the solution of Nitric acid and Ethano.
