Stainless steel signs, as the name implies, are advertising signs made of stainless steel plates by means of corrosion, die casting or printing. Most of the stainless steel signs used at this stage are made by corrosion technology. Such signs have the characteristics of beautiful patterns, clear lines, appropriate depth, flat bottom surface, full color, uniform drawing and uniform surface color. The following introduces the knowledge of stainless steel signs.
Stainless steel is a special material. It is more difficult to make than copper and aluminum. However, it has good resistance to atmospheric and fresh water. It is very beautiful after being corroded, polished and brushed. The fastest corrosion method for stainless steel is electrochemical corrosion, also known as electrolytic corrosion.
Stainless steel sign features:
1. Stainless steel signs have a metallic texture
2, stainless steel signs will not rust, long service life
3, stainless steel signs have a distinction between brushed and glossy
4, stainless steel signs are lighter
5, stainless steel signs are strong and strong
6, stainless steel signs have a high-end feeling
In the product, we are not afraid to see many stainless steel characters. This is because of its unique advantages: stainless steel has a metallic texture; stainless steel has a high-grade feel; stainless steel has a lighter weight; stainless steel has a strong sense of weight; stainless steel has a strong three-dimensional feel; stainless steel has brushed and glossy The distinction is made; the thickness of the stainless steel word is arbitrary; the stainless steel word is generally applied to the company's logo signage, logo wall, and outdoor advertising.
Stainless steel is mainly composed of stainless steel and acid-resistant steel. In short, steel that resists atmospheric corrosion is called stainless steel, and steel that resists chemical corrosion is called acid-resistant steel. Generally speaking, steel with a Wcr greater than 12% has the characteristics of stainless steel. According to the microstructure after heat treatment, stainless steel can be divided into five categories: ferritic stainless steel, martensitic stainless steel, austenitic stainless steel, Austenitic-ferritic stainless steel and precipitated carbonized stainless steel text
Performance damage, defects and some substances affecting the surface, such as dust, floating iron powder or embedded iron, thermal tempering and other oxide layers, rust spots, grinding burrs, welding arc marks, welding splashes, Flux, soldering defects, oils and greases, residual adhesives and paints, chalk and markings. The vast majority are not paying attention to or doing badly because they ignore their harmful effects. However, they are potentially harmful to the oxidized protective film. Once the protective film is damaged, thinned or otherwise altered, the underlying stainless steel will begin to corrode. Corrosion generally does not extend over the entire surface, but at or around the defect. This general corrosion is usually pitting or crevice corrosion, which develops in depth and breadth, while most surfaces are not eroded.
