This process produces black coatings on stainless steel and alloy steels by a "conversion" process. Guruzne Verhofen Explainer. What temperature does stainless steel turn blue? Azzedine Larrode Explainer. How do you make steel blue? Bluing steel is the process of oxidizing the surface to protect it from rust.
You'll need a sander, alcohol wipes, wax and grease remover, bluing solution, cotton balls, sandpaper, a soft cloth, and gun oil. First, you'll need to grind and sand your steel down to remove any finish and make it smooth.
Zugaitz Quispe Pundit. Can stainless steel be colored anodized? Yes, it can be done. It does not have quite the usefulness that aluminum anodizing has. Yes, we can anodize stainless steel to different colors , including black. However in comparison to titanium anodizing , stainless steel colors are not so durable and require some type of protective coating to become durable.
Rigel Huge Pundit. How do you make steel purple? Heat the steel to temperatures from to degrees Fahrenheit, to produce oxidation colors.
At degrees F. These temperatures are commonly used in tempering tool steel. Elizbeth Yahnenko Pundit.
Excessive buffing on stainless steel could result in a grainy appearance so do it with care. Next, suspend the components in a cleaning solution tank to get rid of dirt, oil, grease, and crud. Keep them in that state while you heat them but be sure to not boil up the tank. An ideal temperature is degrees Fahrenheit but it also depends on the manual. Wait for 10 — 15 minutes and then take out the components. Rinse them in a cold water tank after.
You can then u se a soft brush to gently remove all the residue of the cleaning solution on the components. Put all the components into the tank and wait for 5 — 15 minutes. If the solution is still boiling vigorously, then you can expect the bluing to happen naturally. They should start gassing up approximately 2 to 3 minutes after exposure. Then, you can put the components back into the bluing tank and increase the temperature until they turn blue.
Following the treatment in the bluing tank, relocate the components to a cold water tank. Note that it has to be a different tank from the one you used for Step 2. Let them cool down as you take a closer look at the bluing effect. Make sure to check every nook and cranny of the components so that you can find any discoloration or blemishes.
If everything appears good, then you can transfer the components into a hot water tank. In Europe, vanadium and nickel- steel alloys are preferred. Most standard barrels are made with alloy steels , as they offer an excellent balance of strength and cost. The bottom line is that Cerakote will adhere to just about every metal you can come across in the firearms world. The myth of not adhering to as well to stainless steel or Ti was put to rest.
Also the ability to color match optics and parts that are not meant for the oven is invaluable. Use any kind of primer that is rated for stainless steel. Apply your primer. If you want a very smooth application, consider renting a spraying machine from a home improvement store. Begin adding layers of paint. Let dry. Wax the steel once it is completely dry. Stainless is more accurate because you can machine it to closer tolerances than a chrome-moly barrel.
No, it won't last longer than chrome-moly. I've had bolt gun barrels that shot out faster then c-m barrels. The stainless barrels on an average will loose their accuracy about rds sooner than c-m barrels. Bluing is a passivation process in which steel is partially protected against rust, and is named after the blue-black appearance of the resulting protective finish.
Stainless guns can rust, it's just that they are more resistant to rust than carbon steel. If you live in an area that is very humid or wet, if the weapon will be exposed to salt water, if your perspiration eats at a gun , etc. Stainless steel , when used for the overall pistol, is generally selected for it's ability to be less maintenance intensive. Blued steel firearms are more prone to rust and general corrosion than are stainless guns. Do the whole process again.
I do small parts three or four times It starts to get a deep even black polish after the second and third steps. Finally heat the part to around degrees and dunk it in used motor oil. This step would make me concerned about doing it to a barrel but it is vital for the process to keep rust from forming and to freeze the black oxide process. I've got a few parts that I was concerned about doing this with and they have all formed light rust in places.
The shroud below is anodized aluminum. The cocking piece is that's been Black Oxided with the regular stuff. Way to expensive to Blue stainless. My recommendation Cerokote. SO it will work great for mixing bowls but not parts that rub against each other. It has almost the same hardness and black color, just the chemicals used for the bath are slightly altered. We did offer the service but interest for it was to low to make a profit doing it so we mothballed the equipment.
This is why I ask you guys stuff, you have all given me amazing ideas and routes to take.
