NIPPON KINZOKU CO., LTD. has announced the launch of its fourth environmentally-friendly “Eco-Product” series, STA (Special Tension Annealing) finish stainless steel, which eliminates warping and refines crystal grain size for high-definition etching.
In the etching process, spring material warping has been an issue. STA finish greatly reduces this warping, dramatically improving dimensional stability.
Furthermore, in response to demand for smoother etched surfaces, it has achieved finer crystal grain sizes. This makes the product suitable for high-precision microfabrication applications.
These characteristics enable process elimination and simplification, contributing to improved energy efficiency and reduced environmental impact throughout the manufacturing process. Additionally, greater product design flexibility enables the optimization of shapes and specifications, thereby contributing to improved processing efficiency and yield.
