Creating Another Success Story in Vietnam
POSCO STAINLESS STEELPOSCO’s stainless steel products are manufactured by the latestfacilities and technology.
Stainless steel, called the flower of steels, contains more than 12%of chromium and tends to be rustproof. Therefore, it is used asinterior and exterior materials for building, kitchenwares, industrialparts, automotive components, medical instruments and so forth.
POSCO has established integrated manufacturing system frommelting shop to hot & cold rolling process. POSCO produces 2.2million tons of stainless steel products annually.POSCO also pursues complete quality control and deliverymanagement, and strives to achieve customer satisfaction.

A non-glossy cold rolled product that has undergone both annealing and pickling process. Used for petrochemical plant, automobile parts, building materials, pipe, etc.
Skinpassed products of No.2D. Compared to No.2D, it attains a brighter and flatter finish. It is the standard surface with improved mechanical properties. Applicable for almost all uses.
Polished product with 100-120 mesh abraser.Variety of uses including building exterior and interior, various kinds of electronic products, kitchenware that require an attractive glossy finish.
Polished product with 150-180 mesh abraser. It has an attractive silvery-white surface, which is finer than No.3. Used for bathtubs, building exterior and interior, food industry installations, etc.
It is a product with continuous striped pattern acquired by polishing. Most widely used for building exterior and interior.It is also used for sash, doors, panel of building.
After cold rolling, the coil is annealed in a protective gas that prevents oxidisation of the surface and skinpassed. BA product is highly reflective. Also it is used for home appliances, small-sized mirror, kitchenware, building materials and others that require highly reflective properties.
Dull surface is matt finish produced by grinding with a fine rugged roll.Widely used for exterior and interior of train and building that require reduced light reflection.
