What are the typical uses of stainless steel?

Most usage 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, the roofs and side walls of industrial buildings. In these applications, the construction cost of the owner may be more important than aesthetics, even if the surface is not very clean.

The use of 304 stainless steel in dry indoor environments is quite effective. However, in rural and urban areas, to maintain its appearance outdoors, regular cleaning is necessary. In heavily polluted industrial areas and coastal areas, the surface can be very dirty and even produce rust. But to achieve aesthetic effects in outdoor environments, nickel containing stainless steel needs to be used. Therefore, 304 stainless steel is widely used for curtain walls, side walls, roofs, and other building purposes, but in highly corrosive industrial or marine atmospheres, it is best to use 316 stainless steel.

Now, people have fully recognized the advantages of using stainless steel in structural applications. There are several design criteria that include 304 and 316 stainless steel. Because duplex stainless steel 2205 combines good atmospheric corrosion resistance with high tensile strength and ultimate strength, it is also included in European standards.

Product shape

In fact, stainless steel is produced and manufactured in full standard metal shapes and sizes, and there are also many special shapes. The most commonly used products are made from thin plates and strips, and special products are also produced from medium thick plates, such as hot-rolled structural steel and extruded structural steel. And there are also circular, elliptical, square, rectangular, and hexagonal welded pipes or seamless steel pipes and other forms of products, including profiles, bars, wires, and castings.
