Bainitic steel strips

Heat processing (austempering) is conducted in advance; no further heat processing for obtaining spring properties is needed.Therefore, there is no concern about deformation due to heat processing after molding, while saving adjustment processes (cost-cutting) can be expected.
A well-established balance between intensity and processability enables various press processes such as bending.

Applications

Various washers Flat spiral springs

High-precision hardened steel strips

Heat processing (austempering) is conducted in advance; no further heat processing for obtaining spring properties is needed, which is similar to Bainitic steel.
Products with hardness and flatness higher than Bainitic steel strips are available.

Applications

SKS81 High-bright blue[Foil Hardened ribbons] Wrapping carriers SKS81 Cold-finished[Foil Cold finished] Lens diaphragm fins for single-lens reflex cameras

Magnesium-alloy strips

Our cold rolled magnesium-alloy strips have excellent warm pressing properties with high strength achieved by control at the level of crystal.
These magnesium-alloy products have high surface quality and advanced dimensional precision, providing the best coils for streamlining press processing.

Applications

AZ31B[High attenuation] Speaker diaphragms  AZ31B[Light] Lap-top PC housing

High-precision weld-drawn pipes

Our high-quality welding technology and various tests (leak test and eddy-current inspection) provide products at lower cost but with higher precision when compared to seamless pipes.

Applications

Glow plugs Cooling pipes for beer dispensers Medical surgical knives

High-precision deformed steels

Our high-level rolling technology and molding process technology serve to mold your desired cross-section shape into strip forms. Compared to drawing, cutting, or pressing, significant cost-cutting effects can be achieved.

Applications

I bars Guide markers

Sheet working and pressing products

Pressing products

We can offer processing for material arrangements to secondary processing (pressing, etc.) so that products for each part can be available.

Applications

SUS304 Thickness 6.0mm [Pressing products] Heat exchanger production jig

Electromagnetic products

The world's thinnest grain-oriented or non-oriented ultra-thin electromagnetic steel strips (40μm - 150μm) are available.
When compared to thick materials, extremely low iron loss (extremely low energy loss) is achieved.
This feature is especially outstanding in high-frequency areas, while contributing to high efficiency in high-frequency transformers and reactors, along with energy savings.
Furthermore, wound cores and electric equipment produced based on ultra-thin electromagnetic steel strips are also available.

Applications

Ultra-thin electromagnetic steel strips  Wound cores Electric equipment (reactors)

Specimens(almen strips)

・These strip specimens are used for measuring the peening strength depending on the deformation size of the bending that is caused after shot peening.
・These specimens conform to the Japanese Industrial Standards (JIS B 2711: 2013).
・SK85 (C: 0.80-0.90%) is used as the material.
・Tab. 1 shows the dimensions and hardness of each specimen.

Type Nominal dimension Thickness(mm) Width (mm) Length (mm) Hardness Sales unit
N 0.78 0.760 ~ 0.810 19.0 +0、-0.1 76.0 ±0.4 HRA 72.5~76.0 100 specimens
1.3 1.270 ~ 1.320 HRC 44 ~ 50

Relationship of ark height between specimen N and A

(Specimen selection) Use the appropriate type of almen strip for the peening strength within the range of use.
The figure on the left shows the relationship of the almen ark height between specimen N and A under the same shot peening conditions.
Use specimen A normally, while specimen N is used where the peening strength is low.
It is desirable to use almen strips with an almen ark height of 0.6mm or less (0.15-0.6).
