Slab
● Available Specification
Through internal quality control starting from ironmaking process to continuous casting
process, KRAKATAU POSCO’s slab is produced in minimum impurities process which lead to slab
product with the best cleanliness.

Why Choose KRAKATAU POSCO’s Slab?
③ Casting slab product with smooth surface and reliable internal quality by usingsoft-reduction technology
Soft-reduction : Preventing centered segregation with dynamic parameter to
optimize segregation monitoring
Grade 1 based on Mannesman Standard
*) Checked through Macro Etch and S-print test
② Tight control of impurities and solved gas to reduce inclusion and deliver moltensteel with excellent quality through integrated refining process
- 1st refining (KR-BOF) : remove main impurities (S, C, Mn, Si, P), add Fe-alloy
- 2nd refining (RH-LF) : 2nd adjustment for alloy addition, remove gas inside
molten steel and slag modification for catch inclusion
Excellent internal quality
① Tight control of iron ore extraction to produce high ratio of molten iron
- Balancing molten iron temperature (1,5000C) to minimize occurence of impurities
- Control ore basicity to make homogeneous slag
- Low cost production by maintain O/C (ore : coke ratio) at 5.0

Why Choose KRAKATAU POSCO’s Plate?
● Plate can be produced within 3 weeks afterplacing order *for common order
● Secures world-class delivery assurancesame as POSCO does.
● Rolling process is precisely controlled as low as possible atthe minimum allowable temperature (i.e SS400 <9500C)
※ Advantages : - Ensure supreme formability without cracking
- Increase scale adhesion
- Maintain bright surface
● Rolled with precise levelling control to ensure residual stress-free products
- Temperature control during hot leveller process by deforming plate above transformation temperature(>7230C or eutectoid point)

① Cleanliness ② Production Time
③ Formability & Machineablity
● Uses high quality slab with reliable internal
quality
※ Checked through Macro Etch and S-print test
● Plates are produced by using technology
transferred from POSCO that has advanced
quality control
