Addressing environmental issues! We also respond to environmental burden substances and compliance with the RoHS directive.
"SP Processing (Super Passivation)" is a groundbreaking stainless steel surface modification technology that generates a corrosion-resistant layer through a unique surface treatment technique, further enhancing stability. The newly developed products "SP Bronze" and "SP Black," designed to provide even higher corrosion resistance in oxidation coloring, particularly emphasize the corrosion performance of chromium (SUS410, 430). [Features] - High corrosion resistance that can be considered semi-permanent - Particularly for martensitic stainless steel (SUS410 series) tapping screws and drill screws, corrosion resistance has improved by about 20 times compared to conventional products - Available at a low cost that is not much different from conventional treatment prices → Mass production method using a fully automated dedicated line For more details, please contact us or download the catalog.
