Dranoel Posted August 8 (edited) How far into the steel does case hardening go? Will it effect the steel deeper than bluing? The reason I ask is that I was having an idea for my next project and wanted to try something different. Most of my builds I blue then slide the polish the flats back down to bare metal. But I'm wondering if I can case harden the slide, then blue over top of the case hardening and then polish the bluing off the flats to take it back down to a polished color case hardening. Can I even blue over CCH? Edited August 8 by Dranoel Quote Share this post Link to post Share on other sites
Yondering Posted August 8 A few things to point out: - "Case hardening" is a broad category that covers a lot of different hardening processes and depths. Nitride treatment, for example, is case hardening. - Color case hardening is one category of case hardening with varying methods to achieve it, but generally it is mostly decorative and the hard zone is relatively shallow. - The appearance of color case hardening is purely cosmetic and is easily worn off or removed, and sometimes will fade on it's own. If you blue a color case hardened surface, that color is gone. You can't polish off the blue and expect anything but bright steel underneath. Quote Share this post Link to post Share on other sites
