Enhancing Aesthetics and Protection for Stainless Steel

Metal Finishing Group provides black oxide treatments specifically for stainless steel components. This specialized chemical process creates a dark, attractive finish directly on the stainless steel surface. It enhances the material’s inherent corrosion resistance while offering a non-reflective, uniform appearance.

Stainless steel is chosen for its excellent corrosion properties, but sometimes a black finish is desired for aesthetic reasons or to minimize glare. Our black oxide process for stainless steel addresses this need. It maintains the material’s fundamental integrity, making it suitable for applications where visual appeal, reduced reflectivity, and an added layer of protection are critical.

Our Black Oxide Stainless Capabilities: Specialized Processes for Superior Results

We offer tailored black oxide services for various grades of stainless steel, ensuring a consistent and high-quality finish.

  • High-Temperature Alkaline Process: We utilize a specialized hot alkaline bath chemistry, designed to effectively blacken the passive chromium oxide layer characteristic of stainless steel.
  • Aesthetic Enhancement: Provides a deep, uniform black finish that complements the design of your stainless steel parts.
  • Corrosion Resistance Boost: Adds an extra layer of protection, particularly when followed by an oil, wax, or lacquer post-treatment. This helps further deter surface corrosion.
  • Minimal Dimensional Impact: The conversion coating forms an exceptionally thin film, ensuring no significant change to precision part dimensions.
  • Post-Treatment Options: We apply appropriate post-treatments to seal the oxide layer and optimize corrosion performance.
  • Broad Stainless Steel Compatibility: Our process works effectively on various 300 and some 400 series stainless steel alloys.

Properties of Black Oxide Stainless:

Black oxide applied to stainless steel imparts several key properties, enhancing both its function and appearance:

  • Enhanced Corrosion Protection: While stainless steel is inherently corrosion resistant, the black oxide layer, especially when oiled, provides an additional barrier against atmospheric and chemical exposure.
  • Non-Reflective Finish: The black surface significantly reduces light reflection, which is crucial for components in optical systems, instruments, and military applications.
  • Improved Aesthetics: Delivers a sleek, modern black appearance that can improve the marketability and visual appeal of products.
  • Minimal Impact on Mechanical Properties: The process does not negatively affect the mechanical properties or hardness of the underlying stainless steel.
  • Clean and Dry Finish: The black oxide process results in a clean surface, which can be further improved by subsequent sealing.

Applicable Specifications We Adhere To:

Our black oxide processes for stainless steel meet or exceed relevant industry standards, ensuring the quality and performance of your components. We regularly process to:

  • MIL-DTL-13924 (formerly MIL-C-13924) Class 4
