Latest company news about can you blue stainless steel ?

The process is called "bluing". Bluing, also known as oxidation treatment, is a way to treat the surface of metals such as stainless steel in order for it to become corrosion resistant. The resultant thin layer gives the metals a deep-blue or black look. Bluing is commonly used to improve aesthetic appeal for firearms knives and other metallic objects. Here's a simplified explanation of how you can blue stainless steel.

Material and equipment needed:

  1. Blued stainless-steel item
  2. Bluing solution is available commercially.
  3. Degreasing solution (e.g., acetone or a specific metal degreaser)
  4. Abrasive pads or fine abrasive steel wool
  5. Protective gear (gloves, goggles)
  6. Heat source
  7. Sandpaper (various grits)
  8. Linseed oils or gunstock lubricants (for cold bluing).

Blue Stainless Steel Stainless Steel Steps:

  1. Safety Reminders:

    • Make sure that you are in a well-ventilated space.
    • Wear protective clothing, including goggles and gloves to protect against chemicals and heat.
  2. Clean Stainless Steel :

    • Remove any dirt, grease or existing coatings using a degreasing liquid. Ensure the surface before you begin is clean, dry and free of any grease.
  3. Preparing the Surface:

    • Use fine steel cloth or an abrasive to smooth the stainless-steel surface if it has any scratches or imperfections. Sand the stainless-steel with increasingly finer grits, until it's smooth.
  4. Heat Stainless Steel Stainless Steel:

    • Use a propane torches or heat guns to heat the stainless-steel evenly, until it reaches about 300-600degF. The temperature may differ depending on the blueing solution.
  5. Applying the Bluing solution:

    • As the stainless surface is still very hot, evenly apply the blueing solution. Spread the solution evenly with a clean cloth. The heat will trigger a chemical response, turning stainless steel black or dark blue.
  6. Repeat the Instructions as Many Times As Necessary

    • The heating and bluing processes may need to be repeated several times. You should be careful not to overheat your metal. It can cause it to discolor.
  7. A Cleaner Way to Cool Down and Clean Up:

    • Allow the stainless metal to cool on its own. Rinse it with water once it's cooled.
  8. Protecting Blued Surfaces:

    • Apply a thin coat linseed/gunstock oil on the surface to protect it. This will keep your bluing in good condition and help prevent rust.

This process can result in a blued surface that may not last as well as other coatings. It is primarily intended for decorative purposes. The type of bluing you choose may affect the solution and technique used. So, be sure to pay attention to the instructions.
