316Most of the use requirement is to maintain the original appearance of the building for a long time.When determining to choose the type of stainless steel, the main consideration is required in the aesthetic standards, local atmospheric corrosion, and to adopt cleaning system.
Other applications, however, more and more just pursue structural integrity or impervious.For example, industrial building roof and side wall.In these applications, the construction costs may be more important than aesthetics, the surface is not very clean.
The use of effect of 304 stainless steel in dry indoor environment is quite good.However, in the country and city to maintain its appearance, in the outdoor, cleaning should be carried out regularly.In serious pollution of industrial area and coastal regions, the surface is very dirty, and even produce rust.But for outdoor environment the aesthetic effect, we have to nickel stainless steel.
So, 304 stainless steel is widely used in curtain wall, lateral wall, roof and other construction purposes, but in industrial or Marine corrosive serious atmosphere, had better use 316 stainless steel.Stainless steel sliding door, now, people have fully realized the advantages of using stainless steel in structural applications.There are several design criteria included in the 304 and 316 stainless steel.Because duplex stainless steel 2205 have good resistance to atmospheric corrosion performance and high tensile strength and elastic limit strength together,hence , also included the steel in the European standards.
The product shape, in fact, the stainless steel is the standard shape and size of metal production, and there are many special shapes.The most commonly used product is made of sheet and strip, also used in the heavy plate production of special products, for example, production of hot-rolled steel and extrusion structure steel structure.And circular, elliptical, square, rectangular and hexagonal welded pipe or seamless steel tube and other forms of products, including profiles, bars, wires, and casting etc.
