Since France obtained the first patent in 1935, the development of 2205 stainless steel plate has gone through three generations in the 20th century. The first generation of 2205 stainless steel plate is represented by 329 steel developed in the United States in the 1940s, which contains high chromium and molybdenum, good local corrosion resistance, but has a high carbon content (≤0.1%C). The 3RE60 steel developed by Sweden in the mid-1960s is now an ultra-low carbon type 2205 stainless steel plate. Since the 1970s, the development of secondary refining technology and the discovery of the important role of nitrogen in maintaining phase balance and improving corrosion resistance have become important milestones for 2205 stainless steel plates, and the ultra-low carbon type N-containing second-generation 2205 stainless steel plates have been developed, and its representative steel grade is 2205. On this basis, by further improving the alloy content and PREN value, the third generation of 2205 stainless steel plate, namely super 2205 stainless steel plate, was developed in the late 1980s. Its PREN value is greater than 40. Representative trademarks include SAF2507, UR52N+, ZERON100, etc. This type of steel has a higher content of alloy elements such as chromium, nickel, molybdenum and...
There are significant differences between stainless steel pipes and galvanized pipes in many aspects: First of all, from a material perspective, stainless steel pipes are made of high-quality stainless steel and have excellent corrosion resistance, high temperature resistance and high strength properties. In contrast, galvanized pipe is coated with a layer of zinc on the surface of the steel pipe through electroplating or hot-dipping, aiming to enhance its corrosion resistance. However, the material properties of stainless steel pipes are significantly better than galvanized pipes. Secondly, from the perspective of appearance and service life, the surface of stainless steel pipes is smooth, beautiful and not easy to rust, thus ensuring long-term use. In contrast, galvanized pipes are prone to rust on their surfaces, affecting their appearance and service life. In addition, the relatively light weight of stainless steel pipes makes them easier to handle and install, while galvanized pipes are relatively heavier. In terms of application scope, due to its excellent performance and wide range of application fields, stainless steel pipes are widely used in various industries. For example, it is used in the petrochemical industry to transport corrosive media; in the food industry, it is used in pipelines to transport...
In today’s industrial and construction fields, stainless steel pipes have become an indispensable and important material with their excellent performance and diverse uses. Among them, 201 stainless steel pipes stand out among many stainless steel pipe products with their unique advantages. 1. Performance characteristics of 201 stainless steel pipes Good corrosion resistance 201 stainless steel pipes contain a certain amount of chromium and nickel elements, which make them have good corrosion resistance in general environments and can resist the erosion of atmosphere, water and some weakly corrosive media, thereby extending the service life of the pipes. High strength and toughness After special processing technology, 201 stainless steel pipes have high strength and toughness, can withstand greater pressure and impact, and still maintain stable performance under complex working conditions. Good processing performance 201 stainless steel pipes are easy to cut, weld and bend, and can be made into pipes of various shapes and specifications according to actual needs to meet the requirements of different engineering projects. Beautiful appearance Its surface is smooth and bright, with good decorative properties, which can enhance the overall aesthetics of the product. 2. Application fields of 201 stainless steel pipe Architectural decoration Due to its beautiful...
