Japanese Kamiyama Tekkosho Develops Blanca Heat Treatment
Add to my favorite
The company made its first attempt into the heat treatment field in 2020 and developed "Zero Chromate", a chrome-free electroplating technology, and this time went on to develop RoHS and REACH compliant "Blanca" heat treatment used on SUS410 stainless steel screws. "Blanca" means "white" in Spanish. The name implies the visually appealing and damage-free heat treatment. It sustained 4,000 hours in a salt spray test. It prevents red rust and corrosion, can self-heal and fasten stainless steel plates.
