For 400 series alloys, try a 33% by volume of SSB370 and 67% by volume water solution or a

25% by volume of SSB370 and 75% by volume water solution.

Difficult to blacken surfaces may require the use of SSB370 at full strength (100% by volume).

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.
