Stainless steel waste

Nord holding operates with stainless steel waste according to the norms of the
 Waste Management Act.

Stainless steel waste is chrome-nickel pieces, parts,
shavings, etc. with different nickel contents.

In the nomenclature of Nord holding, they are divided into 5 types:

Types of stainless steel waste

  • STAINLESS STEEL WITH 8%
    minimum nickel (Ni) content
  • STAINLESS STEEL WITH 9%
    minimum nickel (Ni) content
  • STAINLESS STEEL WITH 10%
    minimum nickel (Ni) content
  • STAINLESS STEEL FROM SHREDDING INSTALLATIONS
    separated when shredding old cars
  • STAINLESS STEEL TURNINGS

Stainless steel is categorized as a ferrous metal, but it is not attracted to a magnet.
It is a steel alloy with chromium and nickel content in different ratios.

Stainless steel waste is accepted without the presence of other metals and admixtures, impurities,
and the turnings and shredding materials – without excessive moisture and oil.

When receiving stainless steel waste, same are checked for radioactivity
and categorized according to Nord holding’s nomenclature based on origin and nickel content.

The nickel content is determined using a chemical analysis device.

After acceptance, the stainless steel waste is sorted, cut into sizes,
baled as necessary and delivered to recycling facilities.

Recycling process

In theory, stainless steel waste is 100% recyclable. The chromium,
nickel and molybdenum contained in their composition are extremely valuable raw materials with a high value.

Stainless steel waste is recycled by being used in the production of new stainless steel.

  • SHREDDING
    Shredding of stainless steel waste.
  • CHEMICAL ANALYSIS
    Chemical analysis of the shredded fraction and separation by type.
  • MELTING
    Stainless steel scrap and raw materials are melted together in an electric arc furnace.
  • ANALYSIS AND CORRECTIONS
    The molten material is analyzed and adjustments are made to the chemical composition according to the product specifications.
  • PREPARATIONS
    The molten material is cast into billets.
  • END PRODUCTS
    Plates, sheets, rods, wire and others are produced from the billets.

In the production of stainless
steel are used about:
