Cold Rolled Stainless Steel
Use advice for data set Scope: The declaration applies to 1 ton of cold rolled stainless steel product produced by Outokumpu. The Life Cycle Assessment is based on data from the following Outokumpu production plants: - Outokumpu Nirosta GmbH, Dillenburg, Germany - Outokumpu Nirosta GmbH, Krefeld, Germany - Outokumpu Stainless AB, Avesta, Sweden - Outokumpu Stainless AB, Nyby, Torshalla, Sweden - Outokumpu Stainless Oy, Tornio, Finland - Outokumpu Stainless USA LLC, Calvert, AL, USA - Outokumpu Mexinox S.A de C.V., San Luis Potosi, Mexico Production has been modeled using annual production data from 2017. Where required averaging is based on production output from each site. System boundary: This EPD is cradle-to-gate with options, and includes the following process steps: Upstream production of raw materials, fuels and energy and all relevant upstream transport processes. Production/manufacturing of the stainless steel product. Waste water and treatment of wastes generated on site including swarf, dusts, scrap, slag and waste water. End-of-life (recycling, remelting or disposal of steel scrap).
Technical purpose of product or process Cold rolled products are used in a wide range of applications in building and construction. Typical applications are building envelopes, interior cladding and paneling, heating, cooling and ventilation, lifts and elevators.

General comment on data set This EPD describes cold rolled stainless steel products produced by Outokumpu Oyj. Cold rolled products are supplied as coil, sheet or plate. Cold rolled stainless steel has excellent dimensional tolerances and high surface quality. A number of sheet widths and heights are available to meet the various design specifications and requirements. A multitude of surface finishes are also available, including patterned, wet or dry polished. This EPD is applicable to homogeneous Outokumpu cold rolled products which are used in the construction and building industry.

Technology description including background system The steel scrap is melted in an electric arc furnace to obtain a steel melt. The liquid steel is further refined (adjustment of sulphur, carbon and phosphorous) and alloyed to give stainless steel the required characteristics. The molten steel is then cast into semi-finished steel products like slabs or billets. The semi-finished steel products are hot rolled and then annealed and pickled and cold rolled to a desired thickness. If required, they can also be pattern rolled or polished. Declared unit: The declaration applies to one ton of cold rolled stainless steel product. The declared unit is the production and recycling of one ton of cold rolled stainless steel product.
