How to Protect Steel from Corrosion. Hot Bluing

Рет қаралды 47,456

Жыл бұрын

Bluing is a passivation process in which steel is partially protected against rust using a black oxide coating. It is named after the blue-black appearance of the resulting protective finish.
In order to successfully blue your steel you need to heat it to a temperature of 300-400 degrees Celsius (bluish color) and then dip it into the vegetable oil.

its nice, but this process makes the steel a lot hard to stain

It's for estheticis only. Never heat steel for structural purposes.

Yes, you right 👍 Better to use cold bluing on tempered steel.

I think it is extra virgin whale oil from endangered norwales, mixed with rendered fur seal blubber.

@@7rixee Yes, you must use this formula for bluing your steel as well! The rendered baby fur seal oil, in my opinion, is what adds the beautiful bluish colour. The other oils will make the steel item corrosion resistant. But, the beautiful bluish colour is all baby fur seal oil. Why even try to blue anything without the ever important baby fur seal rendered oil? It would be barbaric, even cruel towards the steel. Love the steel, club a seal!

Making the item of stainless steel, originally, is the only way to stop salt water corrosion. But that is preemptive rust prevention. If the item is already made out tcof steel, nothing will stop if from corrosion from salt water. You may be able to slow down the corrosion. But inevitably, that metal will rust

If you live on the coast, you’ve seen stainless corrode. Just takes a lot longer.

So, rust removal agent like wd-40 is actually not required?

@bennyboyy7 4 ай бұрын

Wd 40 removes water, not rust. Since it's an oil it just helps with a lot more than removing water.

@@mocknugget It does work! like others pointed out, you don’t have to worry about corrosion but if you want the blued color then you can definitely do this. Just don’t do it on anything that is tempered because you will lose the tempering.
