NIKRA – High Alloyed Nodular Rolls
Unlike MX Rolls, the micro-structure of NIKRA is based on carbided martensitic and bainitic. Similarly NIKRA is applicable for late intermediate and finishing stands widely. Due to its hard surface, preferred to improve of surface quality of rolled bar, round bar, and such a long round products at finishing stands. The rolls chemically consist higher Nickel and Molybdenum than regular sphero rolls.
