TiN

Titanium nitride is an extremely hard ceramic material, often used as a physical vapor deposition coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.

We suggest that you add coating to your slide, however we do not make you. Stainless slides do not need coating as much as carbon steel slides do. Both can rust (yes stainless can rust) it all depends on the grade of metal and the conditions in which the slide is in.

We no longer offer a cold bluing solution. If you choose to not have a coating on your milled slide, it will be returned back to you milled and oiled. By purchasing this product you agree to these terms and conditions. We are not responsible if your slide rusts or corrodes when selecting no coating
