1)钢筋混凝土中的应用。在钢筋混凝土构造当选用不锈钢筋,是用以进步强度和抵御苛刻的海洋环境以及在混凝土中构成的氯化物对埋入钢筋的腐蚀,耐腐蚀不锈钢混凝土在许多海洋建筑物的桥面(例如美国CoosBay大桥满足强度耐蚀和地震请求,免维护运用寿命可达120年)、桥墩、码头、桩基、防坡堤、锚泊系统、系船具、舷梯、栏杆上运用,也可在化学工业和其他耐蚀请求高的重要的工艺设备的根底构造中运用,在城市的根底设备方面如美国新泽西州的过街天桥也采用不锈钢筋混凝土构造,与普通碳钢钢筋相比,不锈钢筋前期费用是高些,但从其良好的综合性能和运用寿命上思索还是合算的。

1) Application of reinforced concrete. Stainless steel bars are selected for reinforced concrete structures to improve strength and resist severe marine environment and chloride corrosion of embedded steel bars in concrete. Corrosion-resistant stainless steel concrete is used on the deck of many marine buildings (such as CoosBay Bridge in the United States to meet the requirements of strength, corrosion resistance and earthquake resistance, maintenance-free service life of up to 120 years), piers, wharfs, pile foundations and prevention. Slope embankment, mooring system, mooring gear, gangway, railings can also be used in the chemical industry and other important process equipment with high corrosion resistance requirements in the foundation structure. In the urban foundation equipment, such as the overpass in New Jersey, USA, stainless steel reinforced concrete structure is also used. Compared with ordinary carbon steel reinforcement, the cost of stainless steel reinforcement is higher, but from its good comprehensiveness. It's cost-effective to think about it in terms of service life.

2)屋顶的应用。应用不锈钢作屋顶的早期建筑有伦敦的Savoy大酒店、欧洲之星火车站、纽约的Chrysler大厦、帝国大厦等,20世纪90年代在亚洲建成的吉隆坡双塔佩重纳斯大厦、上海金茂大厦、香港的会展心,2002年为世界足球赛新建的日本札幌市穹顶体育场屋顶相继采用。

2) Application of roof. The early buildings using stainless steel as roofs include Savoy Hotel in London, Eurostar Railway Station, Chrysler Building in New York, Empire Building, etc. In the 1990s, Kuala Lumpur Shuangta Pei Chongnas Building, Shanghai Jinmao Building and Hong Kong Convention and Exhibition Center were built in Asia. In 2002, the dome stadium roof of Sapporo City, Japan, which was newly built for the world football match, was adopted one after another.

3)装饰工程中的应用。除了墙面、柱面外、自动伸缩门、卷帘式门、阶梯围栏扶手、阳台扶手、雨水落水管、旗杆、路灯杆、拱廊框架外,在居民住宅的厨房卫生间台面、水槽、支架等,应用日趋增加,装饰工程应用的钢的牌号以304居多,316也有应用。

3) The application of decoration engineering. In addition to walls, columns, automatic telescopic doors, curtain doors, stepped fence handrails, balcony handrails, rainwater drainage pipes, flagpoles, street lamp poles, arcade frames, the use of kitchen bathroom countertops, flumes, brackets in residential buildings is increasing. Steel grades for decorative engineering applications are more than 304 and 316 are also applied.

4)给水工程中的应用。随着经济快速开展、人民生死水平的进步,城镇住宅、公共建筑和旅游设备大量兴建,对生活用水和热水供给提出更新的请求,水质问题倍受关注,给水工程中作为常用管材的镀锌钢管因其易被腐蚀,呈现“红水”、“绿水”现象难以进步水质,又因渗漏较多运用寿命短而被专家预测将逐步退出历史舞台,而塑料管、复合管及铜管在平安牢靠、卫生环保、经济耐用方面不如不锈钢更具有优越性,国内外工程理论证明不锈钢是给水系统在综合性能好、能保证给水质量的节能和环保管材。

4) Application of water supply engineering. With the rapid development of economy and the progress of people's life and death level, a large number of urban residential buildings, public buildings and tourist facilities have been built, and renewal of domestic water and hot water supply has been requested. Water quality problems have attracted much attention. Galvanized steel pipes, as common pipes in water supply projects, are prone to corrosion, showing "red water" and "green water" phenomena, which make it difficult to improve water quality, and because of leakage, their service life is short. It is predicted by experts that plastic pipes, composite pipes and copper pipes will gradually withdraw from the historical stage, but they are less advantageous than stainless steel in terms of safety, reliability, sanitation, environmental protection and economic durability. Engineering theories at home and abroad prove that stainless steel is the best energy-saving and environmental protection pipes for water supply system with the best comprehensive performance and the best guarantee of water quality.

中国无缝管网登载:薄壁不锈钢由于强度高、韧性好、低温下不变脆、热膨系数小、不渗不漏经久耐用、卫生无毒不污染、本钱效益高、再应用率可达100%的优势在建筑给水工程中得到越来越多的应用。日本在建筑物内外推行不锈钢供水管已有25年的历史,东京供水管全面不锈钢化后保证水质清洁卫生,大大降低了维修率和渗漏现象,节约水源,在阪神大地震后坚持完好无损。新加坡立法规则城市供水必需采用不锈钢管线,美、英、法都有不锈钢管规范世界兴旺国度在给水、水处置工程中应用不锈钢日趋普遍。

China Seamless Pipeline Network: Thin-walled stainless steel has been used more and more in construction water supply projects due to its advantages of high strength, good toughness, no brittleness at low temperature, low thermal expansion coefficient, no leakage, durability, sanitation, non-toxicity, non-pollution, high cost-effectiveness and 100% reuse rate. Japan has been carrying out stainless steel water supply pipes inside and outside buildings for 25 years. After the stainless steel water supply pipes in Tokyo are fully stainless, the water quality is clean and hygienic, the maintenance rate and leakage phenomenon are greatly reduced, and the water source is saved. After the Hanshin earthquake, the water supply pipes in Tokyo are in good condition. Singapore's legislation stipulates that stainless steel pipes must be used for urban water supply. The United States, Britain and France all have stainless steel pipes to regulate the application of stainless steel in water supply and water treatment projects in the prosperous countries of the world.
