Tohoku Steel Co., Ltd.

Special Alloy

Melting / forging
We provide wide variety of materials including ferrous and nonferrous alloys in a small lot and in a short period of time.
Development / testing
Our expertise technoloy can assist customers to develop new materials, manufacture prototypes, and to analyze materials and components.

Melting / forging

It answers to such needs!
Process Features Manufacturing range
  • From nonferrous metals to ferrous metals with a cobalt, nickel or copper base, we provide special alloys (magnetic material, heat-resistant alloy, low-thermalexpansion material, electronic use material and target material for coating) made up of various compositions.
  • By mixing strictly selected raw materials and vacuum/atmospheric melting, we can narrowly control the compositions of materials, which is demanded especially for functional materials.
  • By performing high vacuum melting/refining which is difficult in a large vacuum furnace, we are able to manufacture clean alloys with a low-level of gas components.
  • Ingots are available in square or circular shapes, and various sizes, to meet a wide range of customer needs.
  • We also deal with materials other than the examples mentioned. Please feel free to contact us for details.
Dissolved component examples

Ingot size
  • We perform forging of materials provided by customers and even deal with an integrated manufacturing from melting to forging processes.
  • We can manufacture various dimensions of square, circular and rectangular shapes.
  • We can also deal with dimensions other than those mentioned, so feel free to contact us with any questions.
Manufacturing Dimensions

Development / testing

Our technical strength are cultivated and accumulated form our long-term development and manufacturing of new materials through cooperation with research organizations, Tohoku University, and its related institutions in Sendai.

Material development

To help improve function of existing materials corresponding to customers' requirements and develop new materials.
Generally, we perform material development tasks under nondisclosure agreements.
Technical Division is responsible for development tasks for heat-resistant steel and soft-magnetic stainless steel.

Analysis / testing
  • Purchased materials seem to be different from the usual.
  • Although the same ingredients are supposedly being used, the quality of a product seems different.
  • What type of foreign material could be mixed in?
    And where did it come from?

When these sort of issues arise, we will assist in finding solutions.

Delivery time

Although delivery times will vary according to the timing of reception of order, we can have the cast material delivered in two weeks to a month, and forged ingots in a month to a month and a half.
