Need blue coating (oxide) on stainless steel to withstand 450 °F

Q. I am looking for a fluorescent blue coating on stainless steel that can withstand 450 °F in an adhesive environment. Prefer an oxide, powder coating is too thick for the .005" wire diameter, not a decorative application.

A. Stainless steel can be heat tinted, 540 -600 °C temp. (blue to dark blue). PC controlled kiln is best heat source. If heat treatment are not good for your objects same colours can be produced by anodizing(or chemically).

Good luck! (according to Dettner/Elze:Handbuch der galvanotechnik [adv: this book on eBay, AbeBooks, or Amazon], Muenchen 1969.)
