Part Number:- SSB370

Stainless Steel Blackener 370 is an acidic liquid concentrate used full strength or diluted with up to 3 parts water to blacken stainless steel at room temperature. Recommended for color coding parts and blackening engravings on stainless steels. Produces a pleasing dark gray/black finish. No sealer required.

Please note, ALL stainless steel surfaces are passive by nature and may require activating.

This is done by immersing your part into a solution of 50% Hydrochlric Acid, which is available at nearly all hardware stores.

The second picture of the clip and hook is of 316 stainless steel and required the acid dip, and after that it went black almost immediately. 

When diluting any acid always pour acid into water. NEVER the other way around.

316 Stainless Steel  always needs activating, othere stainless steels may not. 

If they wont blacken and you haven't activated them, activate them.

Hydrochloric acid is the acid used by brickies to clean off excess mortar.
