Insta-Blak 335 is recommended for blackening cold and hot rolled carbon steels, alloy steels, tool steels, as well as cast iron, forged steels and powered metal. It will even blacken A2 Tool Steel without using a prep (although it may have a small amount of smut). It will not blacken stainless steels.

Insta-Blak 335 works well for properly cleaned steel sheets and parts for inferior architectural steel finishes. 

Insta-Blak 335 is Perfect For: 

  • Tools/fasteners, firearms, architectural surfaces, and furniture 
  • Steel sheets and architectural surfaces 
  • A2 Tool Steel 
  • Expedited Shipping 

How to Use: Insta-Blak 335 

Insta-Blak 335 is a liquid-based solution that produces a black finish equal in depth of blackness and in corrosion resistence to that obtained with the conventional hot black oxide processes.
