Application
1. Construction field: 430 stainless steel pipes are widely used in the construction field for indoor and outdoor decoration and structure. It can be used to make stair handrails, doors and Windows, railings and other metal products. Because of its bright appearance and strong corrosion resistance, it can maintain a good surface state for a long time, so it is widely used in the construction field.
2. Petrochemical and chemical industry: 430 stainless steel pipes are used to transport various corrosive media in the petrochemical and chemical industry. Because of its excellent corrosion resistance, it can withstand high temperature and high pressure environment, so it is widely used in petroleum, chemical, natural gas and other fields of pipeline system. In addition, 430 stainless steel pipes can also be used to make chemical equipment, reactors and storage tanks.
3. Energy industry: In the energy industry, 430 stainless steel pipes are widely used to transport oil, natural gas and other fluids. Stainless steel material has corrosion resistance, which can effectively prevent corrosion and leakage inside the pipeline to ensure the safe transmission of energy.
4. Pharmaceutical industry: 430 stainless steel pipe is widely used in the pharmaceutical industry. It can be used to make medical instruments, surgical instruments and medical equipment. Stainless steel has good sanitary properties and corrosion resistance...
Advantage
1. Formability, economy, corrosion resistance, oxidation resistance and other functions
2. Do not add nickel and molybdenum and other precious alloys, with cost advantages
3. Ferritic stainless steel has high ferromagnetism and thermal conductivity, which is very suitable for the use of heat exchange
