Their excellent weather resistance, decorativeness, and structural strength perfectly meet the core demand of modern architecture for "aesthetics, durability, and environmental protection". They can be seen in high-end buildings and people's livelihood facilities.

In building structures and envelope systems, stainless steel plates can be used for core components such as exterior wall curtains, roof supports, and curtain keels of high-rise buildings. For example, the exterior wall of the Shanghai Tower adopts a large number of stainless steel decorative plates, which combine modernity with wind and earthquake resistance. At the same time, they resist erosion from harsh environments such as acid rain and salt spray, greatly extending the service life of the building and reducing later maintenance costs. In coastal, industrial polluted, or high-humidity areas, duplex stainless steel (such as 2205), due to its outstanding corrosion resistance, is often used for structural parts such as bridge railings and roof drainage systems, achieving lightweight design while ensuring structural stability. In addition, stainless steel plates have become key structural materials for special working condition buildings such as China's Antarctic Kunlun Station due to their low temperature resistance and high ductility.

In indoor and outdoor decoration, stainless steel plates can present diverse decorative effects through surface treatments such as mirroring, brushing, and etching, and are widely used in scenes such as elevator car panels, stair handrails, background wall decorative strips, and hotel lobby ceilings. Among them, 201 stainless steel has a low cost and is suitable for decoration in non-humid environments; 304 stainless steel, with better corrosion resistance, is often used for decoration in humid areas such as bathrooms and kitchens. In outdoor facilities, bus stops, street lamp poles, and landscape sculptures also often use stainless steel plates. For example, the well-known stainless steel mirror sculpture "Cloud Gate" presents a unique reflection effect through polishing technology and has become a city landmark.

In livelihood building supporting facilities, stainless steel plates are ideal materials for water supply pipes and water tanks. Their corrosion resistance and clean health can avoid secondary pollution of water quality and meet drinking water standards. At present, they have been widely used in urban water supply systems and drinking water projects in the transformation of old communities. At the same time, with the increasing demand for elevator installation in old communities, stainless steel plates, due to their ease of cleaning and durability, have become core materials for elevator cars and handrails, with huge potential demand in the future.

II. Industrial Fields: Withstanding Severe Working Conditions to Support Industrial Upgrading

The industrial field has strict requirements for material properties. Stainless steel plates, with their high temperature resistance, strong corrosion resistance, and high strength, have become core materials for industries such as chemical engineering, petroleum, energy, and food processing, ensuring the safety and stability of production processes.

The chemical and petroleum & natural gas industries are key application scenarios of stainless steel plates. In chemical production, stainless steel plates are used to manufacture equipment such as reaction kettles, heat exchangers, storage tanks, and transportation pipelines. They can resist corrosive media such as sulfuric acid and hydrochloric acid. Among them, high-molybdenum stainless steel such as 316L and 904L is often used to handle severe corrosion conditions. The phosphate fertilizer production industry widely uses 317L stainless steel to resist phosphoric acid corrosion. In the petroleum & natural gas industry, offshore platform equipment and submarine oil transmission pipelines often use duplex stainless steel (such as 2507), which has outstanding chloride ion corrosion resistance and a service life of more than 20 years; oil well pipes in deep-sea oil wells use super duplex stainless steel to withstand high pressure and sulfide stress corrosion, ensuring mining safety.

In the energy field, the application of stainless steel plates covers multiple segments such as nuclear power, thermal power, solar energy, and hydrogen energy. In nuclear power equipment, 316L stainless steel is used in pressurized water reactor systems to withstand high temperature and high pressure water quality and neutron irradiation; high temperature and high pressure pipes and steam generators of thermal power equipment are also inseparable from the support of stainless steel plates. In the solar energy field, stainless steel grades such as SUS304 and B445J1M are used to manufacture collectors, insulation water tanks, and connecting pipes. With the advantages of long life and non-toxicity, they have become the basic materials of solar water heaters. In the hydrogen energy industry chain, 316L stainless steel is used for the inner liners of high-pressure gaseous hydrogen storage tanks, and liquid hydrogen storage tanks use austenitic stainless steel or special alloys. Pipes and valves of hydrogenation stations also need stainless steel materials resistant to hydrogen embrittlement and corrosion.

In the food processing industry, stainless steel plates, due to their non-toxic, harmless, easy-to-clean, and food safety standard-compliant characteristics, are widely used in the manufacture of production equipment. From food conveyor belts, reaction kettles, and mixers to storage tanks in milk processing factories and beer brewing equipment, most use 304 or 316L stainless steel to ensure no metal contamination during food production. In addition, catering equipment such as commercial stoves, steam boxes, and buffet insulation troughs often uses stainless steel plates as inner liners or panels that are resistant to high temperature and soup corrosion.

III. People's Livelihood Consumption Fields: Integrating into Daily Life to Improve Quality Experience

Stainless steel plates are closely related to people's daily lives. Their characteristics of beauty, durability, and ease of cleaning are widely used in livelihood products such as home appliances, kitchenware, and sanitary ware, providing convenience and quality assurance for people's lives.

In the home appliance industry, stainless steel plates are key materials to improve the texture and durability of products. A large number of stainless steel plates are used in refrigerator panels (color stainless steel or laminated plates), washing machine inner drums (304 stainless steel), range hood shells, microwave oven cavities, and oven inner liners. Among them, oven inner liners often use 430 stainless steel, which is high temperature resistant and easy to clean; washing machine inner drums use 304 stainless steel to prevent clothing wear and rust and extend the service life of home appliances. With the promotion of the consumer product trade-in policy, the demand for stainless steel home appliances such as refrigerators, dishwashers, and integrated stoves has continued to rise, further driving the demand for 200-series and 300-series cold-rolled stainless steel plates.

In the kitchenware and tableware field, the application of stainless steel plates is the most common. 304 stainless steel, with high nickel content and strong acid and alkali resistance, is suitable for making pots, knives, tableware, and other products that directly contact food; 430 stainless steel is often used for kitchenware shells, tableware knives and forks, etc. After polishing, the surface is smooth and meets food safety standards. In addition, kitchen sinks and countertopss are often made of stainless steel plates, which are practical, beautiful, easy to clean, and not easy to breed bacteria.

In the sanitary ware field, stainless steel plates, with their corrosion resistance and ease of cleaning, are used to make products such as hand sinks, bathroom cabinets, and shower partitions, especially suitable for humid environments such as bathrooms. At the same time, stainless steel plates are also used to make various containers, which are exquisite in appearance and delicate in structure, not only reflecting life taste but also facilitating daily care.
