Blackening stainless steel help
Blackening stainless steel help
(OP)
I need to blacken some stainless steel parts and was told that heating them up to around 600 degrees C would do the trick, but half a canister of mapp gas later I'm convinced that's a load of crap.
I found some chemical coating kits for sale on the internet but I'm very sure that I could get the components locally for much cheaper and faster than I could on the net. What would be a good combination of chemicals that would allow me to do this?
I've found a few mixes on the yahoo answers forums, but before I go spending money on things and find out that they don't work, I'd rather ask the experts here and get a surefire recipe the first time out.
thanks guys

If you can get by with a coating you might want to checkout Dampney or Hi Temp Coatings.
Personally I've only seen truly black SS once or twice in my time and that came from a nitriding process that went wrong. You have to remember that Stainless is Stainless and there is essentially no oxide to work with.
