1 – Your new favorite hobby; 2 – Brass vs. There are two general types of black oxide for iron and steel: hot black oxide (or hot blackening) and … Some hardened and specialized steel alloys may blacken to a deeper black finish when activated using our Black Oxide Activator. Because stainless steels have a tightly adhered oxide layer, it is critical to break through this layer in order to ensure that the surface consists of free iron for conversion. Place the penetrating sealant provided with the black oxide kit into a clean bucket. was originally developed to provide easy and effective blacking of Iron and Steel components at room temperature. Black Oxide, like other coatings is used to provide protection to the part, achieve a required appearance or achieve other desired properties. Black Oxide Basics What is Black Oxide? Instead, the black oxide coating is produced by a chemical reaction between the iron on the surface of the ferrous metal and the oxidizing salts present in the black oxide solution. Using some scrap pieces of steel, I made a “Z”-shaped bar to suspend the parts from and clamped it to the table. Ground shipping only to the Continental USA. Dip the stainless steel into the penetrating sealant supplied with your oxidation kit. Price List Black Oxide Process (Mild Steel): Minimum Charge: $108.50 up to 50 lbs, .95¢ per lb thereafter Black Oxide Process (4130, 4340, HRS, D2, A-36 Heat Treated Materials) Minimum Charge: $125.00 up to 25 lbs, $2.10 per lb thereafter To tame these coatings, I usually use a citric acid solution or Evaporust to remove rust. Remove the metal from the oven and take it to a ventilated area. Black Oxide Stainless Steel Nuts Bolts and Washers are the most common form of black oxide fastener available. A black oxide conversion coating is applied to ferrous alloys when oxidizing salts react with the iron to form magnetite (Fe 3 O 4), the black oxide of iron. Black oxide coating is used mostly for Carbon steels, Alloy steels, Tool and die steels and Cast irons. It's been around for 50 years or more, says Mr. Ruhland. A black coating can be formed on steel parts in certain types of heat treating processes. Black Oxide works on steel or iron parts only and will not blacken Stainless Steel - use Stainless Steel Blackener. Black Oxide Stainless Steel Nuts Bolts and Washers are the most common form of black oxide fastener available. When fasteners are dipped into the black oxide bath materials (warm and hot processes) the harsh chemical components convert the top layer into magnetite. Read package directions to determine length of immersion for specific materials. Black oxide: Many pieces of reproduction hardware are coated with black oxide to protect them from rust during transport to market. When properly sealed, Presto Black finish will resist rust, and is lab tested for up to 1,200 hours of humidity without chipping or peeling. Best way to get a blacked finish on steel is FeCl3 otherwise know as Ferric Chloride. Compared to nearly all other finishes, black oxide finishes can be applied at significantly lower operating costs. Shake off any excess and allow to dry thoroughly before handling. Parts to be black oxide finished are best suspended into the bath so they don’t touch the bottom or the sides. A Simple to follow room temperature process. I am assuming your parts are steel and yes it is the oil that provides the corrosion resistance on Black oxide coating for this material. Next, submerge the iron source in the oxidizing agent and wait for it to yield rust, which can take anywhere from several hours to a week depending on the strength of your oxidizing agent. Oscura Blackened Steel can be blackened or given colors ranging from dark brown to black. This process is pretty similar to seasoning a cast iron pan. Hot black oxide for stainless steel parts consists of the same steps, except for the proprietary blackening bath. Though standard Black Oxide is set up for steel, it can be done on other substrates including stainless steel, copper, and brass among others. This process can develop a deep black oxide over the surface of the steel. To make iron oxide, start by getting an iron source with as much exposed surface area as possible, like steel wool. … Problems may occur, I'm not sure, if the method you are going to use is different than the method that was used, I'm no expert. Bluing may be applied by immersing steel parts in a solution of potassium nitrate, sodium hydroxide, and water heated to the boiling point, 275 °F to 310 °F (135 °C to 154 °C) depending on the recipe. 3. Black oxide is an inexpensive finish that is used to protect metal objects, such as golf clubs or tools. Remove the part from the solution and rinse in fresh water. Brush on or spray method may also require a stronger mixture. A Summary of BLACK-IT 's features:. The Lumiclad® Black Oxide process (patent applied for) is the first and only high quality method for blackening aluminum that doesn't involve the complexities and high costs of electrolytic black anodizing. This means that the black oxide is not deposited on the surface of the substrate like nickel or zinc electroplating. Some soft black steel wire is ideal for a hook. The appearance of black oxide on any metal object is a uniform black finish. Wipe the stainless steel with a clean, lint-free rag to remove the excess sealant. Pull out the metal and let it cool. Black Oxide works on steel or iron parts only and will not blacken Stainless Steel. Then, choose an oxidizing agent, such as hydrogen peroxide, bleach, or salt water. Black oxide is a finish applied to iron and steel. The black oxide treatment is also referred to as gun bluing. Actually I've had the best luck doing an in-shop quasi black metal treatment on steel by doing it "blacksmith" style, heat it up and dunk it in some oil (I'm lazy so I actually spray it with CRC or LPS). 2 – Carbon Steel Black Oxide; 3 – Stainless Steel Black Oxide; 4 – Torching a Putter; 1 – Basic. Black oxide failure happens when an ingredient is poorly applied or the process isn’t performed according to an exactingly conferred operational doctrine, but chemical composition isn’t the only factor that’s causing trouble. Contains Hazardous Goods. However, most blackening is done after the heat treat cycle in order to give the best control over the results on a variety of alloys. This black oxide finish also enhances the sales appeal for your products. Shipping restrictions apply. Stainless steels and Copper alloys may also be black oxide coated. ; Safe, re-usable, non-hazardous chemicals. Immerse the steel parts into the tank of black oxide finish chemicals. You can either dip the piece in a container of oil or paint it on with a rag (don't use a synthetic brush, it will just melt). Let the metal get hot in the oven.
