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.
POSCO operates an integrated production system that ranges from steel making to hot rolling and cold rolling, producing two million tons of stainless steel products every year. Stainless steel products can be classified into austenitic stainless steel, ferritic stainless steel and martensitic stainless steel according to their alloy components and tissue structure. Their typical applications include car exhaust pipes, kitchen appliances, electronics and construction materials. Emerging applications include eco-friendly sectors, such as EV battery cases and LNG.

 

Product variants

  • Austenitic Series(300 Series)

    This stainless steel is the most widely used of all its kinds. It contains chrome and nickel and features good formability, weldability and anti-corrosion. The most common austenitic stainless steel is Type 304. There are also other notable austenitic stainless steels-Types 316L, 321 and 304J1 to name a few-produced by adding different alloy elements such as Mo, Ti and Cu. Main applications of austenitic stainless steel include kitchen utensils, construction and chemical instruments.

 

  • Ferritic Series(400 Series)

    For ferritic steel, chrome is one of its alloy components. This gives the steel low thermal expansion and a good resistance to corrosion. The most common austenitic stainless steel is Type 430. There are also other notable austenitic stainless steels-Types 409L, 430J1L and 444 to name a few-produced by adding different alloy elements such as Ti, Nb and Mo. Its main applications include exhaust systems and home appliances.

 

  • Martensitic Series

    Martensitic steel contains 12 percent of chrome. Its higher content of carbon compared to other types of steel can give it greater hardness through quenched heat treatment. Its main applications include cutlery and disc brakes.

 

  • Duplex Series

    Duplex steel combines austenitic and ferritic steels to provide higher strength and better resistance to corrosion. It is extensively used for industrial purposes including water tanks and desalination installations.
