I got a client whom I get to build a cool set of traditional-ish andirons for an outside rumsford style fireplace... He wants them to stay "black" and I am not sure how its possible to make that happen... The fireplace is covered, kind of a open patio area with a big timber framed cover... but still outside.... I figure if they have a fire often enough it wont be a huge issue but if its months then I am worried about rust... This is not a huge dollar deal but its a couple grand and I need to be able to tell the guy how to maintain the iron somewhat... Any help??

Whatever you are, be a good one.

Larry, Have you considered linseed oil? We've had reasonable results on A36 with an initial
wipe down at a dull red to black heat. An occasional additional wipe down with a light coat and rag for maintenance. Haven't used it in your exact situation. Your results may ....

Have you experimented with the Inconel?

does he ever plan on actually having a fire in this fireplace?
any finish you put on will eventually burn off and begin to rust.
at work the finish we put on almost everything is a mixture of linseed oil, turpentine and Japan drier.
we flash the water off with the torch and apply the mixture. depending on the type of finish we are looking for we then take stove bright high temp spray it over the surface and lightly take a cup brush to it until it dries.

you might try a sample on some scrap take and spray it down with stove bright high temp, let it dry then lightly cup brush it. It usually gives the painted finish a more glossy natural steel look. I'm not sure how long it will hold up though.

I'd be interested to find out what you end up doing, and what works! good luck!

How bout quenching it in dirty motor oil at a black heat? Soap and water get the stink off, and it does really work.........

A couple of hardware stores around me still carry 'stove black' which is a liquid wax with graphite powder in it. Makes a nice black finish and it's easy to renew. Another possibility is high temp black with wax or stove-black over it. That gives a much different texture than black paint combined with the protection of the paint underneath.

I think with an outdoor fireplace the client is either going to have to accept paint or the need for regular maintenance to prevent rust.

Larry,

This looks like a good candidate for forged stainless. This is great for oustside fireplaces, You have those big hammers for the the 304.

You might want to try a product called Briwax, color, Ebony. It is available from Woodworkers Supply. It is a black wax which I put on warm and blackens the steel very nicely and holds up well. Not sure in a fire situation though. It would work for touch up after the fire to keep them black. I have put it on cold for touch up and works well.

Make 'em from 410 & don't poslish or passivate. Stays gray forever. Dishwashers won't even shine it back up!

No matter where you go... there you are.

I think the stainless recommendations sound interesting... I could have tried to push that if I would have had the suggestion earlier in the project... No money in it for stainless at this point though.. I had some time to work on it this week and have made some progress

I dont think you should loose any sleep over not being made of stainless. Some time ago my roommate and I thought we would be coolCool and make a firepit that would not look like a rusty piece of crap all the time so we cut open one of our empty kegs and afrter 2 or 3 fires we had the same rusty crap as we wanted to avoid:( When making bbq's we need to use steel firebox and stainless skin with an air gap so it stays good.
