stainless steel recycling flow

Life of stainless steel products

Stainless steel is characterized by its excellent corrosion resistance and durability, and widely used in various fields by taking advantage of the characteristics.Old stainless steel products and life-expired stainless steel machines no longer in use are scrapped and recycled.

Important as rare metals

Nickel (Ni) and chromium (Cr) contained in stainless steel are generally said to be high in scarcity value. These metals are defined as rare metals in Japan. It can be said that they are metal resources of high material recycle importance.

Working with Metal One Corporation and the Metal One Group to contribute to the upstream area through to the downstream area of the stainless value chain.

Metal One Stainless Raw Materials Corporation makes maximum use of its know-how on stainless steel scraps and the Metal One Group’s advantage of scale. As a company playing a key role in the stainless value chain at the start and end of the material flow that ranges from the upstream area to the downstream area of the stainless value chain, Metal One Stainless Raw Materials Corporation contributes to the stable supply of stainless steel materials that can be recycled by 100%.

Radioactivity detection equipment

Efforts toward the proper disposal of valuable recyclable resources

Stainless steel is an ideal material for recycling. As one of our efforts toward the proper disposal of this valuable recyclable resource, we introduced detection equipment to each of our major worksites. The load on each vehicle passing the security gate is inspected in order to prevent the intrusion of radioactive materials into recycling resources.
