Posco Specialty Steel is aggressively developing new products such stainless steels, tool steels, Ni-alloys in order to maintain the customer's satisfaction and quality improvement.
We completed development of the followings.


CIMA35 C and Mo are added into the INVAR, these modified alloys are used for high-power-transmission wire
  due to both high strength and low thermal expansion coefficient
INVAR 36A It is used for the communication facilities by low thermal expansion coefficient which is
  about 1/10 in comparision with general stinless steel
SCA10, 12 It has so superior corrosion resistance characteristics that is useful for recuperator pipe
CSS446M alloy for electric parts
CSS FCA2 refactory-strengthening alloy


Furthermore, we are investigating the INVAR alloys such CSS 36A for Bi-Metal, CSS 42A for electric gun COVAR29-18 for glass sealing. in particular, we are studying the high grade-high alloyed steel such M46 which is high-speed tool steel using spray casting. Posco Specialty Steel Coporation focuses on the new materials through the consistent R & D in order to grow into the first-class special maker.
