Most of the 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 adopted. Increasingly, however, other applications simply seek structural integrity or impermeability. For example, roofs and side walls of industrial buildings. In these applications, the owner’s cost of construction may be more important than aesthetics, and the surface is not very clean. The effect of using 304 stainless steel in a dry indoor environment is quite good.
However, to maintain its appearance outdoors in both the country and the city, frequent washing is required. In heavily polluted industrial areas and coastal areas, the surface will be very dirty and even rusted. However, 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 corrosive industries or marine atmospheres, it is best to use 316 stainless steel. There are several design criteria that include 304 and 316 stainless steel.
Because “duplex” stainless steel 2205 has integrated good atmospheric corrosion resistance with high tensile strength and elastic limit strength, this steel is also included in the European standards. Product shape, in fact, stainless steel is manufactured in all standard metal shapes and sizes, and there are many special shapes. The most commonly used products are made of sheet and strip steel, and special products are also produced from medium and thick plates, for example, the production of hot-rolled structural steel and extruded structural steel. There are also round, oval, square, rectangular and hexagonal welded or seamless steel pipes and other forms of products, including profiles, bars, wires and castings. To meet the aesthetic requirements of architects, a number of different commercial finishes have been developed.
3d printing field
Stainless steel itself has good corrosion resistance, and stainless steel can still maintain its excellent physical and mechanical properties at high temperatures. It is also widely used in the field of 3D printing.
