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.

Its excellent weather resistance makes it suitable for outdoor use. However, it may not be ideal for installations in coastal or highly corrosive environments.

Current equipment supports up to 300 mm width. New equipment under development aims to handle up to 600 mm.
