Steel making company POSCO began the development of the Bi free-cutting steel in 2005, which is both harmless to the body and environmentally friendly.
Until now, free-cutting steel contained lead for ease of processability. It is high in strength but easy to cut and form long steel wire rods. Concerns over the possibility of lead accumulating in the body and eventually proving fatal has lead to the development of this new improved version.
Bi, which is found in digestive medicine, drinks and cosmetics, is used to replace lead to maintain the processability of the steel. 1.5 million tonnes of lead free-cutting steel is produced per year, of which 35,000 tonnes is imported to Korea. This is set to be replaced by the Bi free-cutting steel, and therefore contribute to increasing profitability as a high value added product compared to other steels.
The product is currently being used as the official material for TV designs after receiving quality certification from LG Electronics, and is due to be applied to all TV products by the company from 2012. POSCO has once again proved its dominance by being the first to succeed in mass production development of harmless environment friendly free-cutting steel.
