Outokumpu - Stainless Steel Manufacturer for Pulp and Paper Applications

A world leader in stainless steel, Outokumpu supplies the pulp and paper industry on every continent with the materials, expertise and support required to build more cost-efficient plants. This focus has led to long-term partnerships (over 60 years in some cases) with many of the world's leading suppliers to the pulp and papermaking businesses.

Our customers expect a great deal of us. They expect us to be right on the cutting edge - all the time. They expect us to be responsible and farsighted corporate citizens, providing materials that are not only tough enough to handle punishing conditions, but also resistant enough to meet increasingly stringent environmental legislation. That's why we have refined our duplex grades over many years. Today, we offer a broad spectrum of grades to meet varying corrosive environments.

Our plants, mainly situated in Finland, Sweden, Britain and the U.S., produce a wide range of stainless steel products including hot and cold rolled coil, sheet and plate, precision strip as well as tubular and long products. Our products are available in various dimensions, grades and surface finishes.

Outokumpu produces part of its raw material in its own chromium mine and ferrochrome facility. Outokumpu operates in some 30 countries and employs 11 000 people. The level of annual sales is some six billion euro. Outokumpu Oyj is listed on the Helsinki stock exchange.

STAINLESS STEEL PRODUCTS

For pulp and paper applications, Outokumpu supplies most types of stainless steel products including:

• Hot rolled quarto plate
• Hot and cold rolled plate, sheet and coil
• Tubes and pipes
• Fittings and flanges
• Long products (billets, rods and bars)
• Suction roll shells

DUPLEX ADDS STRENGTH TO STAINLESS

Duplex stainless steel high strength to weight ratio provides options other grades cannot match - with no compromise in performance. Take cost, for example: A wall thickness reduction of 50% compared to carbon steel and 35% compared to clad steel is well within reach, offering a welcome cost reduction to equipment suppliers across the industry.

The rising popularity of duplex stainless steels opens up a wide range of new applications, including batch and continuous pulp digesters as well as some pulp bleaching systems. It's cost-efficient, flexible, easy to weld and long lasting. So it's easy to see why duplex is rapidly becoming the construction material of choice.

LDX 2101® - AIR REPLACES EXPENSIVE NICKEL

LDX 2101 is the latest additional contribution in the duplex stainless steel family with the same desirable properties as other duplex stainless steels - high strength, good corrosion resistance, welding and engineering properties.

LDX 2101 has a low nickel content, replaced by nitrogen (from air) and manganese, which implies a low and stable price and together with the high strength it is a cost efficient alternative to lower strength stainless steels as well as coated C-Mn steels.
