In response to the growing demand for higher performance and faster processing in analytical and medical devices, NIPPON KINZOKU has developed two innovative products based on its FINE PIPE technology: "High-Precision Inner Surface" small-diameter tubes and "FINE PEEK-ST" stainless steel and PEEK resin composite tubes. These products align perfectly with the industry's shift toward extreme precision, resulting in a surge of inquiries and expanding orders for the “FINE PIPE” series.

NIPPON KINZOKU’s “FINE PIPE” Series Welded Drawn Pipes Outperforming Seamless Pipes

Fine Profile is a generic term for products made by continuously processing ferrous and nonferrous metals into irregularly shaped cross sections with different thicknesses in the width direction using our unique rolling technology. It contributes to customers' process reduction, environmental improvement, manufacturing cost reduction, and yield improvement as an alternative to various processes such as cutting and grinding.

NIPPON KINZOKU’s Cold Profile Rolled Products Are Named "Fine Profile” to Strengthen Sales Expansion

The scale of the global diabetes crisis is expanding. In line with this trend, the global demand for insulin needles continues to escalate. Furthermore, insulin delivery is evolving toward "painless" experiences that reduce patient burden. Modern designs prioritize minimizing pain and bruising, leading to the widespread adoption of ultra-fine needles. This trend is further supported by the growing popularity of compact, portable pen injectors. Additionally, the global rise in weight-management medications—which also utilize these ultra-fine needles—is further accelerating market expansion. We supply NK-304NKM, a specialized stainless steel for thin-walled welded tubes used in medical and cosmetic applications, most notably for "painless needles". This material offers a superior combination of stable weldability and excellent drawability. Our quality advantage is highly recognized and valued throughout the global market.

We have developed our own “FI finish”, a stainless steel surface pre-coated with an inorganic coating (about 1μm in thickness) that offers electrical insulation resistance.

NK-301ZF combines high strength with high ductility, enabling both weight reduction of parts and simplification of manufacturing processes. These characteristics have led to its adoption in a wide range of applications, including smartphone components, diaphragm, and flat spiral spring.

FB (Fine Black®): An extremely thin transparent oxide film is formed on the surface of stainless steel to achieve a metallic look and deep black color through light interference and absorption phenomena. The surface is treated with a special hard film to provide excellent corrosion and wear resistance. M-FB (Matte FB): Developed “Matte tone” FB finish to meet the market need for “matte” products. BA5 (Bright Annealing): In addition to the general metallic glossy BA finish (surface finish by bright heat treatment after cold rolling), the “BA5” finish is even higher glossy by our proprietary technology. PW (Pearly White): Finished in stainless steel with a calm satin tone (aluminum tone). (Graphic: Business Wire)

Introduction of NIPPON KINZOKU’s Original Stainless Steel Grades and Design Variations

By reducing the thickness of the electrical steel strip, eddy current loss (core loss) can be significantly lowered. Eddy currents are electrical currents generated within the electrical steel strip by alternating magnetic fields; they are a primary factor that increases core loss.

Conventional TA (Tension Annealing) finish has been highly evaluated as a stainless spring material with excellent flatness, low residual stress, and dimensional stability after processing. STA finish, which is a further evolution of this finish, minimizes residual stress and is optimized for etching processing.
