Changsha HCADTO Stainless Steel Co., Ltd.

There are three ways to cleaning   stainless steel channel bar : mechanical method, physical method and chemical method. 1. Mechanical method: Using the pressure, impact, shearing, grinding etc. by various manual and power tools to wash it. 2. Physical method: Using arc, plasma, laser, ultrasonic and shock wave to clean the casting. 3. Chemical method: Using hydrofluoric acid to dissolve silicon dioxide and salt electrolysis to remove the sticky sand of small and medium-sized castings; some metals can be oxidized and gas-cut by the fierce oxidation characteristics at high temperatures. HCADTO Stainless Steel Co., Ltd.  the Stainless Steel Division of ADTO GROUP, specializes in manufacturing stainless steel pipes, stainless steel angle bar, flat bar, round bar, square bar, hexagonal bar and channel bar in various grades and sizes. Our years of production experience and manufacturing facilities will ensure the good quality and competitive duration of our products.

  Stainless steel plates  are widely used in our daily life. Many people are interested in the bearing capacity of stainless steel plates. Here we will tell you about its bearing capacity. 1. The stainless steel plate adopts pot bottom structure, which makes its force more uniform and increases its force area. 2. The wear-resistant layer of the stainless steel plate is multi-color quartz sand and adds stabilizers to improve the wear resistance of the product. 3. The reinforcing fiber skeleton is adopted to ensure the high bearing capacity of stainless steel plate. 4. Adopting layered composite technology, using different reinforcing materials in different parts of the stainless steel plate to avoid separation and falling off. HCADTO Stainless Steel Co., Ltd.  the Stainless Steel Division of ADTO GROUP, specializes in manufacturing stainless steel pipes, stainless steel angle bar, flat bar, round bar, square bar, hexagonal bar and channel bar in various grades and sizes. ...

Decorative stainless steel plate : stainless steel products for architectural decoration are thin steel plates, with the thickness less than 2mm. Features: Corrosion resistance, different gloss and reflectivity can be formed by different surface processing. The surface gloss of polished stainless steel plate has the same reflective power as glass. Application: roofs, curtain walls, doors, windows, interior and exterior wall finishes, railings, murals, decorative painting frames, guardrails, stainless steel columns, etc.

Beautiful surface and diversified use possibilities; Good corrosion resistance and longer durability than ordinary steel; High strength; high temperature oxidation resistance and high strength, so it can resist fire; Easy to plastic processing; Clean, high finish; Good welding performance. HCADTO Stainless Steel Co., Ltd.  the Stainless Steel Division of ADTO GROUP, specializes in manufacturing stainless steel pipes, stainless steel angle bar, flat bar, round bar, square bar, hexagonal bar and channel bar in various grades and sizes. Our years of production experience and manufacturing facilities will ensure the good quality and competitive duration of our products.

Stainless steel angle bar   has the ability to resist atmospheric oxidation, that is, non-rust, and it also has the ability to resist corrosion in media containing acid, alkali, and salt, that is, corrosion resistance. However, the size of its anti-corrosion ability varies with the chemical composition of the steel itself, the mutual state, the use conditions and the type of environmental media. Such as 304 material, in a dry and clean atmosphere, it has absolutely excellent corrosion resistance, but it is moved to the seaside area, in the sea fog containing a lot of salt, it will quickly rust. Therefore, it is not any kind of stainless steel angle bar, which is corrosion-resistant and does not rust at all times.　　  Therefore, in order to ensure that the metal surface is permanently bright and not rusted, we recommend:  1. The surface of the decorative stainless steel angle steel must be cleaned and scrubbed frequently to remove attachments and eliminate external factors...

The solution treatment process  is to increase the corrosion resistance of  stainless steel pipe . 1. Intermediate aging After solution treatment, reheated to (760±15)°C and kept for 90min.. Because Cr23C6 carbides are precipitated from austenite, the content of carbon and alloying elements in the austenitic 904L stainless steel pipe will reduce while the Ms point will increase. After cooling to room temperature at 70°C, the martensite + α ferrite + retained austenite structure is obtained, and the retained austenite is decomposed after aging at 510°C. 2. High temperature adjustment and cryogenic treatment method After the solid solution is heated to 950℃ for 90 minutes, a small amount of martensite can be obtained by cooling to room temperature due to the increase of the Ms point, then cold treatment at -70℃ and holding for 8 hours to get few martensite. 3. Cold deformation method After solution treatment, it is cold deformed at room temperature. The amount of martensite form...

The   stainless steel angle bar   is an extremely thin, strong, dense and stable chromium-rich oxide film (protective film) formed on its surface to prevent oxygen atoms from continuing to penetrate and continue to oxidize, thereby gaining corrosion resistance. Once for some reason, the film is continuously destroyed, the oxygen atoms in the air or liquid will continue to infiltrate or the iron atoms in the metal will continue to separate out, forming loose iron oxide, and the metal surface will also be continuously affected. Rust. There are many forms of damage to the surface film, and the following are more common in daily life: 　　  The surface of the stainless steel angle bar accumulates dust containing other metal elements or attachments of foreign metal particles, in humid air , The condensed water between the attachment and the stainless steel angle steel connects the two to form a micro battery, which triggers an electrochemical reaction and damages the protective ...
