Description about normal stainless steel sheets

 

Stainless steel does not cause corrosion, pitting, rust or wear. Stainless steel is also one of the strongest materials in building metal materials. Because stainless steel has good corrosion resistance, it enables structural components to permanently maintain engineering integrity. Chromium-containing stainless steel also combines mechanical strength and high extensibility, making it easy to machine parts to meet the needs of architects and structural designers.

 

Application about stainless steel sheet

 

Most of the requirements for use are to maintain the original appearance of the building for a long time. When determining the type of stainless steel to be used, the main considerations are the required aesthetic standards, the corrosive nature of the location atmosphere, and the cleaning system to be used. However, more and more applications are only seeking structural integrity or water impermeability. For example, the roof and side walls of industrial buildings. In these applications, the cost of building the owner may be more important than aesthetics, and the surface is not very clean. The use of 304 stainless steel in a dry indoor environment works reasonably well. However, in rural areas and cities to maintain their appearance outdoors, they need to be cleaned frequently. In heavily polluted industrial areas and coastal areas, the surface can be very dirty and even rusted. However, in order to obtain an aesthetic effect in an outdoor environment, nickel-containing stainless steel is required. Therefore, 304 stainless steel is widely used in curtain walls, side walls, roofs and other architectural applications, but in aggressive industrial or marine atmospheres, 316 stainless steel is preferred. The advantages of using stainless steel in structural applications are now well recognized. There are several design guidelines including 304 and 316 stainless steel. Because "duplex" stainless steel 2205 has a good resistance to atmospheric corrosion and high tensile strength and elastic strength, this steel is also included in the European guidelines. In fact, stainless steel is manufactured in full-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 produced from medium and heavy plates, for example, hot-rolled structural steel and extruded structural steel. There are also round, elliptical, square, rectangular and hexagonal welded or seamless steel tubes and other forms of products, including profiles, bars, wires and castings.

 

409 409L cold rolled stainless steel sheets

409 stainless steel adds Ti content compared to ordinary stainless steel, which is more excellent in welding performance and processability. It is often used in automotive exhaust pipes, containers, heat exchangers and other products that do not require heat treatment after welding.

409L has a lower carbon content than 409 stainless steel and is superior in corrosion resistance and weldability.
