With the development of society, people pay more and more attention to environmental protection and cost control, so slowly invent various products suitable for the future. Stainless steel is one of them. Stainless steel is currently widely used, ranging from tableware for eating, to aerospace, and weapons on the battlefield. Stainless steel is indispensable. Let me introduce the most commonly used areas of stainless steel.

1. Water industry: Stainless steel is the best material for water industry such as water preparation, storage, transportation, purification, regeneration, desalination, etc. Its advantages are corrosion resistance, earthquake resistance, water saving, sanitation (no rust and copper green), weight Lightweight (reduced by 1/3), less maintenance, long life (40 years of use), low life cycle cost (LCC), etc., and it is a green and environmentally friendly material that can be recycled and reused. At present, the pipeline stainless steel in Tokyo, Japan has reached 76%, and the water leakage rate of the pipeline has dropped from 14.7% to 7.5%. Recently, a bellows joint has been developed, which has reduced the construction cost of stainless steel water pipeline by 20% and the total cost by 3%. , The maintenance cost is reduced by 3/4.

2. Jianye: In terms of construction and decoration, stainless steel is currently mainly used in high-rise building exterior walls, interior and exterior columns, handrails, floors, elevator panels, doors and windows, curtain walls and other interior and exterior decoration and components. The surface-treated, colored, and plated stainless steel plate solves the problem of easy fingerprints after touching, and further expands the application range of stainless steel. Japan has developed a variety of stainless steel roofing materials, such as high and medium chromium ferrite with better corrosion resistance and various coated plates, Sweden developed super-clean brushed surface stainless steel plates, and Ugine developed UGITOP surface plates in France. The industry offers more choices. In 1997, the consumption of stainless steel by Jianye in Japan reached 238,000 tons, an increase of more than four times compared with 1977, and the proportion of steel consumption increased from 10% to 20%. In 1999, Japan Jianye's austenitic stainless steel consumption accounted for 25%, and ferritic stainless steel accounted for 9.5%. Japan’s stainless steel structures have been standardized by legislation. The country stipulated in 2000 that stainless steel rebars used in the United Kingdom in seawater and chloride corrosion environments must be constructed of stainless steel for structures below 60 meters. The life span of stainless steel bridges built in Spain is up to 100 years. It's 80 years.
