Technologies

  • Its excellent weather resistance makes it suitable for outdoor use. However, it may not be ideal for installations in coastal or highly corrosive environments.
  • If the work can be subcontracted to our partners, processing is possible. Please provide detailed drawings and specifications. Note that some shapes or tight tolerances may not be feasible.
  • We specialize exclusively in stainless steel, so we do not process other materials.
  • We do not recommend it for surfaces frequently dragged by pans or ceramic bottoms, as scratches may occur easily.
  • No. Our technology focuses on creating a black finish specifically on stainless steel.
  • We offer our proprietary AFP coating, which makes fingerprints easier to wipe off and less likely to adhere.
  • Yes, we can provide base materials such as sheets and flat bars along with the finishing service.
  • Yes. Matte finishes can be achieved through physical methods like blasting or chemical roughening. Please contact our sales team to discuss your specifications.
  • We can process austenitic and ferritic stainless steels. For other stainless steel types, please consult with sales.
  • Edges cut after blackening will show the base stainless steel’s silver color. Edges cut before blackening will be finished black.
  • Maximum dimensions are approximately 150 mm (W) × 1200 mm (H) × 4000 mm (L). We also have processing tanks for smaller or thin parts.
  • Current equipment supports up to 300 mm width. New equipment under development aims to handle up to 600 mm.
  • Heat-affected zones may not develop the black finish. Removing weld discoloration by grinding and polishing will allow blackening.
  • Reflectance data covers ultraviolet to near-infrared wavelengths (250–2500 nm). Contact sales for details.
  • Visibility depends on product shape. Please consult sales for details.
  • If laser cutting uses inert gases like nitrogen or argon (clean cut), blackening is possible. Cutting with air or oxygen can cause oxidation and prevent blackening.
  • The black oxide film is the same passive layer naturally formed on stainless steel, so it does not need removal and can be recycled as stainless steel.
  • 2B finish often results in uneven color due to a thick oxide layer. Light grinding before processing improves the finish.
  • Due to weight limitations, 5 mm sheets generally cannot be processed. The approximate maximum weight is 70 kg.
  • Unlike paint or plating, Abel Black® forms an ultra-thin oxide film that won’t peel and preserves the metal’s natural texture. It offers excellent corrosion and weather resistance, is stable under temperature changes, and does not cause dimensional changes.
  • The surface achieves a pencil hardness rating of 6H.
  • Scratches present on delivery remain after finishing, so packaging must be agreed upon in advance.
  • Finished products are packaged in the same manner as received. If the surface is highly sensitive, special packaging can be arranged after consultation.
  • Heat alters stainless steel, causing uneven coloration or incomplete blackening.
  • There are finishing methods that do not require jigs. Please contact sales for details.
  • Partial finishing by masking is not possible.
  • Processing is possible but depends on the material. Please consult sales.
  • Yes, shipping is available to Japanese ports. Please consult sales.
  • Current equipment handles SUS304 at 0.15–0.3 mm and SUS430 at 0.15–0.4 mm. New equipment aims to support 0.5 mm thickness.
  • Reflectance is below 1%.
  • The oxide film is ultra-thin, less than 1 µm.
  • Matte finishes require roughening the base surface. Please consult sales.
  • The emissivity is 0.42, higher than bare stainless steel.
  • Up to 300°C without issue.
  • Electrolytic blackening causes no dimensional change. Chemical blackening may cause a slight thickness reduction of about 2 µm.
