In 1970, Kobe Steel was the first in Japan to commence the manufacturing and sale of atomized steel powder. In the years since, the properties of steel powder have been recognized across various fields including automotive components, and steel powder has become widely used for powder metallurgy, environmental applications (contaminated soil, and water purification) under the ECOMEL® name, welding rods, deoxidizers and magnetic applications (MAGMEL®).
Due to its excellent compressibility, steel powder can be used to easily manufacture large high-density and high-strength components.
To leverage expertise accumulated over many years to ensure the stable supply of better quality steel powder, in 1992 Kobe Steel completed the new steel powder plant, and has been continuously delivering good quality steel powder employing superior production technologies under the latest strictly enforced quality control systems.
| High purity. | The minimal inclusions make it ideal for a wide range of powder metallurgy, including powder-forged product parts. |
|---|---|
| Excellent compressibility. | Large high-density and high-strength components can be easily manufactured. |
| Good compactability. | As the powder is made up of irregular shapes it has excellent compressive strength, reducing chipping or cracking of a green compact. |
| Extensive range of brands. | You can choose the right brand to suit the intended application. |
| Stable quality. | We consistently deliver good quality steel powder with our superior production technologies and strictly enforced quality control system. |
| Type | Application |
|---|---|
| Pure Iron powder | This iron powder features good compressibility to produce high-compressibility compacts. Thanks to its high apparent density and good flowability, dice can be quickly filled. |
| Free-cutting steel powder | Compacts that have high density and excellent machinability without sacrificing compressibility can be produced. |
| Low alloy steel powder | This is a high-strength, low-alloy steel powder with good compressibility. Stable heat treatability and a uniform structure can be achieved. |
| Soft magnetic iron powder | Its minimal impurities and good compressibility produce excellent magnetic properties. |
Kobe Steel has developed a method to manufacture uniform mixed steel powder by attaching graphite powder, which tends to segregate during mixing, with steel powder. Manufactured under the name SEGLESS®, it meets the needs of customers looking to improve working environments and reduce labor.
Using this method reduces variability in the amount of carbon in green compacts while also reducing variation in apparent density and dimensional change rate, leading to improved productivity.
