Most use requirements are to maintain the original appearance of the building for a long time. When determining the type of stainless steel to be selected, the main considerations are the required aesthetic standards, the corrosiveness of the local atmosphere, and the cleaning system to be used. However, other applications are increasingly seeking structural integrity or impermeability. For example, roofs and side walls of industrial buildings. In these applications, the owner’s construction cost may be more important than aesthetics, and the surface may not be very clean. The effect of using 304 stainless steel in a dry indoor environment is quite good.
However, in rural and urban areas, if you want to maintain its appearance outdoors, you need to clean it frequently. In heavily polluted industrial areas and coastal areas, the surface will be very dirty and even rusty. But to obtain the aesthetic effect in the outdoor environment, nickel-containing stainless steel is required. Therefore, 304 stainless steel is widely used in curtain walls, side walls, roofs and other construction purposes, but in severely erosive industrial or marine atmosphere, it is best to use 316 stainless steel. There are several design guidelines including 304 and 316 stainless steel.
Because the "duplex" stainless steel 2205 has combined good atmospheric corrosion resistance with high tensile strength and elastic limit strength, this type of steel is also included in the European guidelines. The shape of the product, in fact, stainless steel is manufactured with all standard metal shapes and sizes, and there are many special shapes. The most commonly used products are made of thin plates and strip steel, and special products are also produced with medium and thick plates, for example, the production of hot-rolled structural steel and extruded structural steel. And there are round, oval, square, rectangular and hexagonal welded pipes or seamless steel pipes and other forms of products, including profiles, bars, wires and castings. In order to meet the aesthetic requirements of architects, a variety of different commercial surface finishes have been developed.
3D printing field
Stainless steel itself has good corrosion resistance. At high temperatures, stainless steel can still maintain its excellent physical and mechanical properties. It is also widely used in the field of 3D printing.
