Range of application of 304 stainless steel 304 stainless steel is one of the most widely used chromium-nickel stainless steel, as a widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties;Good thermal processing property such as punching and bending, no hardening phenomenon of heat treatment (using temperature -196℃~800℃).Corrosion resistance in the atmosphere, if it is industrial atmosphere or heavily polluted areas, it is necessary to clean in time to avoid corrosion.Suitable for food processing, storage and transportation.It has good machining performance and weldability.Plate heat exchanger, bellows, household products (Class 1, 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, mold products), medical appliances, building materials, chemistry, food industry, agriculture, Marine parts, etc.304 stainless steel is food grade stainless steel recognized by the country. Most of the requirements are to maintain the original appearance of the building for a long time.In determining the type of stainless steel to be selected, the main consideration is the required aesthetic standards, the corrosive atmosphere and the cleaning system to be used.However, other applications increasingly seek only structural integrity or water impermeability.For example, the roof and side walls of an industrial building.In these applications, construction cost to the owner may be more important than aesthetics, even if the surface is not very clean.304 stainless steel works well in dry indoor environments.However, in the country and the city to maintain its appearance outdoors, it needs to be washed regularly.In heavily polluted industrial and coastal areas, the surface can be very dirty and even rust. But to obtain the aesthetic effect in outdoor environment, we need to use stainless steel containing nickel.Therefore, 304 stainless steel is widely used in curtain wall, side wall, roof and other building purposes, but in the corrosive serious industry or Marine atmosphere, it is best to use 316 stainless steel.Stainless steel sliding door, people have fully realized the advantages of using stainless steel in structural applications.Several design guidelines include 304 and 316 stainless steels.Because "DUAL PHASE" STAINLESS STEEL 2205 HAS a GOOD atmospheric corrosion resistance and high tensile strength and elastic strength integrated, so, the European STANDARDS also include this steel.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. Medium and heavy plates are also used to produce special products, such as hot-rolled structural steel and extruded structural steel.There are also circular, elliptical, square, rectangular and hexagonal welded pipes or seamless steel tubes and other forms of products, including profiles, bars, wires and castings.
