Elemental effects Carbon (C): 1. Improve the blade’s resistance to deformation and tensile strength; 2. Enhance its hardness and improve its wear resistance. Chromium (Cr): 1. Enhances hardness, tensile strength and toughness; 2. Prevents wear and corrosion. Cobalt (Co): 1. Increases hardness and strength so that it can withstand high-temperature quenching; 2. Used in more complex alloys to strengthen certain individual properties of other elements. Copper (Cu): 1. Enhance corrosion resistance; 2. Enhance wear resistance. Manganese (Mn): 1. Increases hardenability, wear resistance and tensile strength; 2. Takes away oxygen from the molten metal through separated oxidation and separated vaporization; 3. When added in large amounts, it enhances hardness, but increases brittleness. Molybdenum (Mo): 1. Enhance strength, hardness, hardenability and...
The corrosion resistance of stainless steel plates can be improved by the following methods: Choosing the Right Type of Stainless Steel: Different grades and types of stainless steel vary in their corrosion resistance. For example, stainless steel with higher chromium content generally has better corrosion resistance. Choose the appropriate stainless steel material according to the specific use environment and needs. Surface treatment: The surface treatment of stainless steel has a significant impact on its corrosion resistance. Common treatments include polishing, brushing, and passivation. These treatments not only improve the appearance, but also enhance the sealing of the chromium oxide layer and improve corrosion resistance. Passivation treatment: Passivation is to form a dense chromium oxide film on the surface of stainless steel by treating it in an acidic or alkaline solution. This treatment can improve the corrosion resistance of stainless steel plates, especially when used in some harsh environments. Coating Protection: Applying a protective coating to the stainless steel surface, such as painting or plating, can provide additional protection against direct contact of corrosion agents with the stainless steel. Regular Cleaning and Maintenance: Regular cleaning of stainless steel surfaces helps prevent the build-up of dirt and chemicals and maintains its corrosion-resistant...
There are many processing methods for antibacterial stainless steel pipes. There are pipe stripping, welding, pipe expansion, shrinking, hot extrusion, cold extrusion, hot rolling, cold rolling, stamping, etc. The processing methods used for antibacterial stainless steel are different for different uses. For example, the country is now promoting thin-walled antibacterial stainless steel water supply pipes, which use antibacterial stainless steel strips that are heated and welded to form antibacterial stainless steel pipes; large-diameter antibacterial stainless steel pipes installed on industrial pipelines Stainless steel elbows are processed by stamping, and installation elbows with irregular angles that are assembled at the construction site after being cut into several sections by plasma are processed by welding. Antibacterial stainless steel pipe cutting: Antibacterial stainless steel pipes are generally 6 meters long. Cutting is the basic type of antibacterial stainless steel pipe processing, including ordinary grinder cutting, circular saw cutting and precision cutting. Precise cutting can shorten the antibacterial stainless steel pipe to 2 mm, and ensure that the cut antibacterial stainless steel pipe has no burrs and the loss can be controlled to within 1mm. Antibacterial stainless steel pipe welding: Welding is also an essential process for antibacterial stainless steel pipe processing. The most...
1. Stainless steel welded pipe material selection Stainless steel welded pipes must pass non-destructive testing, and the welding joints need to be inspected and the welding joints are required to be smooth. Select the material according to the corrosiveness of the flowing liquid or gas, select the pipe diameter according to the flow rate, and select the wall thickness according to the wall pressure requirements. The sealing materials of all valves, pipes and manholes must be qualified. 2. Stainless steel welded pipe manufacturing The upper and lower heads are molded or spun. When assembled with the cylinder, they are mainly docked. All interface parts are mechanically flanged to ensure a sophisticated transition. All welds must not be lower than the base metal. Ideally, they should be flush with the base metal. If they are higher than the base metal, the parts above the base metal must be sophisticated and must not have pits or pits. When docking and welding, ensure that the inner walls of the pipes are connected without gaps. During welding, the stainless steel welded pipes must be fully protected by argon gas, and the purity of the argon gas must reach more than 99%; all welds must...
