OREANDA-NEWS. April 1, 2010. OMZ-Special Steels, a part of OMZ Group, had manufactured an unique support roll billet from a 360-ton ingot for Hyundai Steel (South Korea). The billet is over 10 m in length and 2 m in diameter.

The unique characteristics of the billet involve using a new steel grade with increased chrome concentration. The new steel grade was developed after conducting extensive research and engineering work, ensuring higher hardness on a specified depth along the surface length.

Besides, the original technology had allowed to use differential heat treating without employing expensive equipment. The new differential heat treating mode was developed by OMZ-Special Steels specialists using computer modeling specifically for the Hyundai Steel billet’s size.

The billet is to be shipped soon for final treating, to be performed by Kharkov-based Turboatom plant.
