How to Anodize Steel Black

Anodizing steel black is an easy and popular way to add an attractive finish to metal objects. It requires a few simple steps, but the end result will be worth the effort. This guide will provide step-by-step instructions on how to anodize steel black, so you can get started right away!

Preparing the Steel

The first step in anodizing steel black is to prepare the steel surface for the process. Before beginning, make sure that all oils or other contaminants are removed from the surface of the steel. Use a soft brush and warm water with detergent, then rinse off with clean water and dry thoroughly. You should also sand any rough spots or burrs until they are smooth. Once your object is ready, it’s time to begin the anodizing process.

Anodizing Process

The second step in anodizing steel black is to submerge your object into an acid bath. This will help remove any oxides from the surface of your object so that it can be properly coated with a protective layer of oxide. The type of acid used for this step will depend on what type of metal you are working with; for example, aluminium requires hydrochloric acid, while stainless steel requires sulfuric acid. Make sure you use gloves and safety goggles when handling acids!

Once your object has been submerged in acid for a few minutes, you can move on to applying a voltage to it. Connect one lead of a power supply to your object and another lead (with insulation) to a container filled with electrolyte solution (water mixed with salt). Then turn up the voltage gradually until you reach between 10–15 volts—this will create enough current flow through your object for it to be effectively oxidized. Keep in mind that different metals require different voltages; consult a professional if you’re not sure what voltage level is best for your particular project!


Anodizing steel black is a great way to give metal objects an attractive finish. With just a few simple steps—preparing the surface, submerging it in acid, and applying voltage—you can achieve beautiful results quickly and easily. Whether you’re making jewellery or restoring furniture, this guide will help you get started on achieving beautiful results every time! With just a little practice and patience, anyone can master how to anodize steel black like a pro!
