We perform stainless steel black processing that is harmless and does not affect the human body.
"Stainless Steel Black Treatment" is a technology that takes into consideration the environment and safety by not using harmful substances such as hexavalent chromium. Its characteristics include excellent heat resistance, capable of withstanding temperatures up to approximately 500 degrees. Additionally, it has superior corrosion resistance and significantly enhanced rust prevention. Since the surface of the stainless steel is oxidized to black, there is no worry of peeling off over time like with paint or plating, allowing for a permanent black finish. Of course, the dimensions and thickness due to this processing do not change. 【Features】 ■ Harmless and non-toxic if ingested ■ Does not use harmful substances such as hexavalent chromium ■ Excellent heat resistance (capable of withstanding up to approximately 500 degrees) ■ Superior corrosion resistance ■ Significantly enhanced rust prevention *For more details, please refer to the PDF document or feel free to contact us.
