The POSCO Quality

Stainless Steel

Stainless steel is a special steel featuring a splendid surface and good resistance to rust. As a high value-added product, stainless steel can be used for diverse areas without requiring any additional treatment.

Manufacturing Process

Powered by state-of-the-art facility and technology, POSCO operates a totally computerized, end-to-end full automatic production system. This allows us to deliver high-quality and high-performance products fit to the needs of customers.

1. Steel Making

Steelmaking has the greatest impact on the quality and cost of steel products. POSCO has state-of-the-art AOD, VOD and continuous casting facilities.

2. Hot Rolling

Slabs made in the steelmaking plant are rolled into black coils of highly refined thickness and shape before being made into white coils to the needs of customers through heat treatment, pickling and finishing in the annealing and pickling plant. White coils so produced are used for cold rolling, pipes and sheets.

3. Plates

Slabs produced at the steelmaking plant undergo rolling, heat-treatment and a pickling process, which are then cut into sizes as ordered and delivered to the customer. Thick plates are used by the heavy chemical industries that require corrosion resistance, such as petrochemicals, power plant facilities, paper manufacturing and special shipbuilding

4. Cold Rolling

POSCO is equipped with 20 high cluster mills, bright annealing line, TLL (Tension Leveling Line), AFC (Automatic Flatness Control), AGC (Automatic Gauge Control), which enable the production of cold rolled products of 0.1-3.0mm in thickness and up to 1580mm in width in various shapes and surface treatment.
