In the field of architecture and decoration, the expansion of stainless steel usage scenarios continues to promote the evolution of decoration design. Black is undoubtedly a fashionable and versatile color that can add a touch of elegance and restrained temperament to the space. Black titanium stainless steel plate has become a wide choice for designers in decoration design with its unique appearance and excellent performance. It not only adds a touch of fashion to the space, but also shows excellent performance in functionality.
Black titanium stainless steel is a special surface treatment process to make the surface of stainless steel appear black material.
Material and characteristics
Material type: he base material is usually 201, 304, 316 and other types of stainless steel. These stainless steels themselves have good corrosion resistance and high strength. After black titanium treatment, they add a unique decorative and other properties.
Physical properties: The density of black titanium stainless steel is about 7.92g/cm³, the elastic modulus is 200gpa, the tensile strength is 520mpa, the elongation is 40%, and the hardness is 207hbw.
Chemical properties: Contains a certain proportion of carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel and molybdenum. The existence of these elements makes black titanium stainless steel have good corrosion resistance.
Performance advantages: Not only does it have the original corrosion resistance and high strength of stainless steel, but it also has good wear resistance and UV resistance. The black appearance greatly enhances its decorative effect and can create a high-end atmosphere.
Production process
Electroplating: The color is grayish. Through electrolysis, metal ions are deposited on the surface of stainless steel to form a black titanium layer.
Water plating: The color is darker. It uses chemical reduction reaction to reduce metal ions in metal salt solution into metal atoms to form a black titanium layer on the surface of stainless steel.
Common types
Black titanium with brushed finish: The surface has a filamentous texture. Through the brushing process, the stainless steel surface presents a delicate brushed effect, which enhances the texture and three-dimensional sense. At the same time, it has a certain anti-slip performance. It is often used in occasions with high decorative requirements, such as elevator cars, stair handrails, etc.
Black titanium with matte finish: The surface is matte. After being matte-treated, the stainless steel surface becomes less shiny and presents a soft matte effect. It feels delicate and can effectively hide fingerprints and scratches. It is often used in places that require a simple and low-key appearance, such as kitchen appliance surfaces, interior decorative panels, etc.
Black titanium with mirror finish: Through fine grinding and polishing on ordinary stainless steel plates, and then titanium plating, the surface forms a black titanium layer that is as smooth and bright as a mirror. It has an excellent reflective effect and can make the space look more spacious and bright. It is often used in building curtain walls, high-end decorations, furniture surfaces, etc.
Duration of use
Electroplated black titanium: If it is an ordinary electroplating process, in a general indoor environment, its black coating can remain basically non-fading and non-discoloring for about 5-10 years. However, if it is outdoors or in harsh environments such as high humidity and high salinity, it may fade and discolor in 3-5 years, and even coating peeling may occur.
Water-plated black titanium: The bonding strength of water-plated black titanium is relatively good. In normal indoor environments, its black appearance can be maintained for about 8-15 years. In outdoor environments, if there are better protective measures, such as regular cleaning and coating of protective agents, it can last for about 5-10 years; if there are no protective measures, it may fade or discolor significantly in 3-8 years.
Vacuum ion-plated black titanium: This is a more advanced process. The black titanium coating formed has a strong bonding strength with the stainless steel substrate. In normal indoor use environments, its black effect can last for 15-20 years or even longer. In outdoor environments, it can generally last for about 10-15 years, but if it is in a highly corrosive environment such as the seaside, it may show slight discoloration in about 8-12 years.
Application fields
Architectural decoration: widely used in building facades, curtain walls, door and window frames, roof decoration, etc. For example, some modern high-rise buildings use black titanium stainless steel curtain walls, which are not only beautiful and durable, but also can enhance the overall quality and image of the building; indoors, it can be used to make partitions, railings, decorative lines, etc., adding a sense of hierarchy and fashion to the space. 1.
Home decoration: used in furniture manufacturing, such as surface decoration of tables, chairs, cabinets, wardrobes, etc., which can add a sense of refinement and personality to the home environment; it can also be used to make kitchen supplies, such as stoves, range hoods, sinks, etc., which are both beautiful and easy to clean, and have good corrosion resistance.
Industrial field: It is also used in some industrial equipment with high requirements for corrosion resistance and appearance, such as food processing equipment, chemical equipment, medical equipment, etc., which can not only ensure the performance and service life of the equipment, but also meet the requirements of hygiene and beauty.
