Our proprietary equipment, designed with accumulated cold rolling expertise, and the industry-leading proprietary technologies developed by it, meet all your needs.
Development Background
In recent years, with the miniaturization and higher density of electronic devices and the lightweighting of automobiles, the metal materials used are increasingly required to simultaneously achieve higher levels of both low permeability properties that resist magnetization even after processing and deep drawability that enables the formation of complex shapes. However, achieving both of these properties simultaneously has been a difficult challenge with conventional stainless steel.
To meet these market needs, our company has developed the "NK-305 Series" using proprietary technology. We offer two steel grades that deliver optimal performance tailored to specific applications.
Features and Benefits of the NK-305 Series
1. NK-305S: Extremely low permeability for enhanced reliability of electronic components
It significantly suppresses the generation of magnetism during heavy processing, achieving properties that surpass those of SUS316 - a common low-permeability stainless steel. This makes it ideal for camera modules and various sensor components where magnetic interference must be minimized, contributing to the prevention of product malfunctions. Furthermore, cost reduction is possible by replacing SUS316 with NK-305S.
(Example applications: camera components, mobile device components, etc.)
2. NK-305Y: Excellent deep drawing properties improve productivity for complex-shaped parts
Exceptionally soft with excellent elongation, it handles demanding deep drawing processes. It facilitates forming complex automotive parts and other shapes that were previously difficult to manufacture, significantly contributing to improved processing efficiency and yield in customer production.
(Examples of applications: automotive parts, electronic component enclosures, etc.)
