The Japanese company Nippon Kinzoku Group has announced the launch of a new special tension annealing (STA) made of stainless steel, located under its series of eco-friendly products. The STA finish represents an innovation over conventional tensile annealing, providing higher dimensional stability, minimizing deformation during etching, and finer grain cleaning for high precision applications.
Material properties
The STA finish combines heat treatment and shape correction in one step, providing excellent flatness and reducing distortion. In addition, the refined grain provides smoother etched surfaces.
These improvements make it especially valuable in micro-manufacturing and electronics, where precision is crucial.
Technical Specifications
- Available grades: SUS304, SUS301, SUS430
- Thickness range: 0.1 to 0.5 mm
- Width up to: 600 mm
- Special version: refined grain SUS304 for smoother etched surfaces
Environmental benefits and efficiency
By simplifying processes and reducing the number of production steps, STA finishes increase energy efficiency, reduce environmental impact, and support carbon neutrality goals.
Nippon Kinzoku has officially certified the STA finish as an eco-friendly product, reinforcing its goal for 2050.
