- High strength and excellent processability
- Mass production starting this year

POSCO developed the world`s first environment friendly Bismuth (Bi) free cutting steel and entered mass production.

POSCO started development of the Bi free cutting steel which is harmless to the body and environment friendly since 2005 and succeeded in production development after 5 years, completing preparations for mass production recently.

Free-cutting steel means steel that is high in strength but easy to cut, and is in the form of long steel wire rods, round, thin, and long in form.

Until now, free cutting steel was composed of lead (Pb) due to its excellent processability, but there were opinions that the lead accumulated in the body during processing can be fatal requiring an alternative solution to the health problems of workers.

Accordingly, POSCO started the new product development in 2005, adding Bi which is used in digestive medicine, drinks, and cosmetics, maintaining the processability of lead free cutting steel. The company once again proved its technical dominance by being the world`s first to succeed in mass production development of harmless environment friendly free cutting steel.

1.5 million tons of lead free cutting steel is produced annually, while 35,000 tons are all imported in to Korea. The replacement effect is great by replacing lead free cutting steel with Bi free cutting steel, and it is expected to contribute to increasing profitability as a high value added product compared to other steels.

Bi free cutting steel was registered as official material for TV designs after receiving quality certification from LG Electronics, completing application tests with the first supply in August. The material will be applied to all TV products manufactured by LG Electronics in the new year.
