3. Corrosion resistance
x5crni18-12Stainless steel has good corrosion resistance and can be used for a long time in a variety of corrosive media. Its corrosion resistance is mainly due to its high chromium and high nickel chemical composition. In an oxidizing medium, a dense oxide film is formed on the surface to prevent further corrosion of the substrate. In reducing media, its corrosion resistance will be relatively poor.
Fourth, processing performance
X5CRN18-12 stainless steel has good processing performance and can be used for cutting, bending, welding and other processing operations. During processing, contact with carbon steel should be avoided to avoid galvanic corrosion. When welding, a welding process with low heat input should be used to avoid overheating of the material or intergranular corrosion.
Fifth, the field of application
X5CRNI18-12 stainless steelIt has been widely used in construction, chemical industry, petroleum and other fields. In the field of construction, it can be used to manufacture bridges, towers and other structural parts of high-rise buildings. In the chemical industry, it can be used to manufacture high-temperature, high-pressure reactors, pipelines and other equipment. In the petroleum field, it can be used to make oil tanks, pipelines and other equipment. In addition, it can also be used to manufacture precision components such as medical devices and food processing equipment.
6. Precautions.
in useX5CRNI18-12 stainless steel, the following points should be noted:
1.During use, contact with carbon steel should be avoided to avoid galvanic corrosion.
2.When welding, a welding process with low heat input should be used to avoid overheating of the material or intergranular corrosion.
3.During the processing process, scratches or impacts on the surface of the material should be avoided so as not to affect the corrosion resistance.
