We offer three types of high strength screw wire: an austenite type, a precipitation hardening type, and a conventional hardening type, enabling customers to select a type depending on their needs.
Austenite Type :
| Steel Types | DHS30 |
|
|---|---|---|
| Characteristics | The consistent workability as well as the hardness following screw rolling enables manufacturing of screws with hard ridges. |
Precipitation Type :
| Steel Types | DSP1H | |
|---|---|---|
| Characteristics | Hardness is increased by heat treating after cold working. Corrosion resistance is better than standard Cr type screw materials. |
Conventional Hardening Type :
| Steel Types | NAS600X | |
|---|---|---|
| Characteristics | We have greatly increased the strength and corrosion resistance compared to the previous conventional hardening type screw material, SUS410. |
