Common marking methods in the market are 06Cr 19Ni 10 and SUS304, in which 06Cr 19Ni 10 generally represents national standard production, 304 generally represents ASTM standard production and SUS304 represents Japanese standard production.
Extended data:
Other applications of 304 stainless steel are more and more just to seek structural integrity or impermeability. Such as 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.
304 stainless steel is very effective in dry indoor environment. However, in rural and urban areas, if you want to keep its appearance outdoors, you need to clean it frequently. In heavily polluted industrial areas and coastal areas, the surface will be dirty and even rust will be produced.
However, in order to obtain aesthetic effect in outdoor environment, nickel-containing stainless steel must be used. Therefore, 304 stainless steel is widely used in curtain walls, side walls, roofs and other building applications, but in corrosive industries or marine atmosphere, 3 16 stainless steel is the best choice. Stainless steel sliding door fully embodies the advantages of people using stainless steel in structural application.
Some design standards include 304 and 3 16 stainless steel. "Duplex" stainless steel 2205 is also included in the European specification, because it has good atmospheric corrosion resistance, high tensile strength and elastic ultimate strength. In fact, stainless steel is made of completely standard metal shapes and sizes, and there are many special shapes.
The most commonly used products are thin plate and strip steel, and special products made of medium and heavy plate, such as hot rolled structural steel and extruded structural steel. In addition, there are round steel pipes, oval steel pipes, square steel pipes, rectangular steel pipes and hexagonal welded steel pipes or seamless steel pipes, including profiles, bars, wires and castings.
