High Strength, High Ductility Stainless Steel
TOKKIN's uniquely designed production method for JIN™ brings you a material that combines high strength and excellent workability that cannot be obtained with ordinary manufacturing methods. The balance of Yield stress (YS) exceeds 35,000 MPa x Elongation (EL) is among the highest in the world.
Ultrafine Grain Stainless Steel
nanoSUS™ , a stainless steel in which the crystal grain size of the material is refined to about 1μm. The control of microstructure contributes to improving various properties such as strength, fatigue properties, and workability.
Soft Magnetic Material
SUY-1, nanoMAG™, TDS-1, TDJ-1
Soft magnetic material is easily magnetized when a magnetic field is applied, but returns to its original state when the magnetic field is removed. We also manufacture our original steel grades such as electromagnetic stainless steel with corrosion resistance and extremely high strength.
Nickel Alloys, Cobalt alloys,
Materials based on Ni, Co, and Ti are superior to stainless steel in terms of corrosion resistance and heat resistance. In addition to cold-rolled strips manufactured by our company, we also provide thick plates, wires, bars, and ultra-thin pipes sourced from domestic and overseas partner companies for you.
Electrical Resistance Alloys
Electrical Heating Alloys
We handle various types of resistance alloys: "Electrical Resistance Alloys" to control electricity and electric current, and "Electrical Heating Alloys" that utilize the property of metals to generate heat due to electric resistance. We control Temperature Coefficient of Resistance (TCR), conductor resistance, and guarantee thickness with high precision.
Materials for Bellows
TOKKIN 350, HC-22, HC-276,Alloy625, SUS316L, SUS304L
We manufacture TOKKIN 350 and various other metals for bellows, and we can propose materials and specifications according to required properties such as strength, corrosion resistance, and heat resistance.
Materials for Industrial Knives and Blades
TE-2, SK95, SK85, RB-S, SUS420J2
Material which is used to make various blades such as razor blades, shaver blades, and medical blades. Depending on the application and required properties, you can choose from a variety of options such as high carbon steel or martensitic stainless steel.
Low-Temperature Thermal Spraying
(Cold Spray Method)
Cladding Material│CS cladding
A cladded material by using a new manufacturing method that forms a layer on a base material by using cold spray technology, in which metal powder is accelerated to supersonic speeds and sprayed while in a solid state. It can be used not only for metals but also for resins and ceramics.
High-Precision Thickness Materials
TOKKIN manufactures material from 0.010 to 2.00 mm with tight thickness tolerance which are more precise than that of JIS standards or other competitors, and we guarantee highly accurate thicknesses with less variation over the entire length of strip.
(thickness less than 0.10mm)
Stainless Steel, Iron, Steel, Nonferrous Metal
We can make it to foils (less than 0.10 mm thick) in all the materials we manufacture, from stainless steel, low carbon steel, and other steel materials to nickel alloys, cobalt alloys, copper alloys, and other nonferrous metals.
