POSCO Succeeds in Mass Producing Eco-friendly Graphite Free Cutting Steel

POSCO (CEO Jeong-Woo Choi) succeeded in developing and mass-producing eco-friendly graphite free cutting steel named PosGRAM (GRAphitic steel for Machinability) for the first time in the world and has set to expand sales.

POSCO’s PosGRAM is expected to enhance the national industrial competitiveness, as it is to replace lead free cutting steel, which was entirely reliant on imports.

Free cutting steel is a kind of wire rod product that is specially designed to be machined by chip removal with high productivity. It is mainly used for fabricating parts for automotive and electronic & OA equipment, where complex shapes and size precision are required.
