Recently Posco in Korea have successfully trial manufactured hot rolled stainless coils in cold rolled stainless coils' thickness level, which means Posco is going to proceed into high value- added products market.
The minimum thickness of hot rolled stainless coils is about 1.2mm normally, while Posco's branch factory CEM has succeeded in producing 0.8mm's hot rolled stainless coils, which is the first time in Korea and second in global.
Comparing with 1.2mm's stainless steel coils, it will need higher rolling force to roll 0.8mm's hot rolled stainless coils by 33% or more. Because if taking common rolling way to produce, cracks will happen in coils. At present we usually take pickling treatment to hot rolled stainless coils and roll them into cold rolled coils in normal temperature, which needs more procedures and definately make the cost higher for stainless cold rolled coils.
Up to now this technology only exists in Avidi from Italy. With this sussessful test from Posco, will help Posco to progress the overseas market in the field of hot rolled stainless coils with thickness under 1mm.
