Industrial stainless steel applications

1. Water industry: Stainless steel is the best material for water preparation, storage, transportation, purification, regeneration and seawater desalination. Its advantages are corrosion resistance, earthquake resistance, water saving, hygiene (no rust and copper green) and weight. Lighter (1 / 3 reduction), less maintenance, long life (40 years can be used), low life cycle cost (LCC), and is a green material that can be recycled.

2. Construction industry: At present, stainless steel is mainly used in the construction of high-rise exterior walls, interior and exterior columns, handrails, floors, elevator siding, doors and windows, curtain walls and other interior and exterior decorations and components. After the surface treatment, coloring, and plating of the stainless steel plate, problems such as handprints are easily resolved after the touch, and the application range of the stainless steel is further expanded.

3, the home appliance industry: home appliances industry, the largest stainless steel dosage for automatic washing machine inner tube, water heater liner, microwave oven outer shell, refrigerator lining, and more ferritic stainless steel In general, Western Europe, the proportion of home appliances with stainless steel Big, Asia is only close to Europe in Japan.

4. Environmental protection industry: Industrial waste gas, garbage and water treatment devices need to be made of stainless steel. In the process of flue gas desulfurization, sulfur dioxide and chlorine ions and iron ions must be eroded in the absorption tower, coolers, pumps, valves, and flue pipes. For example, duplex stainless steels and high-grade austenitic stainless steel waste incinerators, waste water treatment facilities, etc. must be used, all of which must be made of high-performance stainless steel.

5. Industrial facilities: The proportion of stainless steel used in industrial facilities in developed countries is generally up to 15% to 20%, but the proportion of applications in mainland China is still very small. Chemicals, petrochemicals, chemical fiber, paper, food, medicine, energy (nuclear power, thermal power, etc.) , fuel cell) and other fields need stainless steel With the improvement of domestic stainless steel product quality and the development of special brand products, the application of stainless steel in industrial facilities in the mainland is expected to increase year by year.

6. Automobile industry: The application of stainless steel in the mainland is mainly concentrated in the automotive industry. In Europe and the United States, it is further expanded to include passenger cars, buses, trains, subway cars, high-speed railway vehicles, etc., showing that the development of the vehicle industry is huge.

7. Various different types of stainless steel are being increasingly and successfully used in various marine environments. It must be pointed out that the long-term corrosion-free corrosion of stainless steel in seawater requires complicated anti-corrosion engineering techniques and substantial investment. Austenitic and martensitic stainless steels have long been used for superheater pipes and turbine blades on marine power plants. It is not easy to maintain a low chloride content in these devices because the application technology of marine power plants is not different from the basic principles of general power plants. Stainless steel is also being used for large-capacity chemical containers on ocean-going merchant ships, and its use is in some ways very different from the conditions of use of land-based chemical plants.

      Most stainless steel grades have satisfactory results in marine applications, but different grades are sensitive to stress corrosion cracking. The martensitic steel represented by type 410 and the ferritic steel represented by type 430 will rust in a few months under marine conditions. This uniform rust can be removed by mechanical sanding. The more popular stainless steel is austenitic stainless steel because of its strong rust resistance (except for stress corrosion cracking). With time, austenitic stainless steels also turn black. If it is for aesthetic reasons or other reasons, this blackening can also be removed by sanding. Stainless steel rarely produces uniform rust candles in seawater, so you don't have to worry about it in actual use.
