304 stainless steel is a common material in stainless steel with a density of 7.93 g/cm³, which is also called 18/8 stainless steel in the industry. High temperature resistance of 800℃, good processability and high toughness, so it is widely used in industry, furniture decoration industry and medical industry, and we can see this material in daily life, just like extra large thermos.
304 is a kind of universal stainless steel, which is widely used to manufacture equipment and parts that require good comprehensive properties (corrosion resistance and formability), For example, a large hot water thermos cannot store corrosive food for a long time. In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a brand of stainless steel produced according to American ASTM standard.
304 stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical characteristics, so it will be used to make cute thermos bottles; Moreover, it has good hot workability such as stamping and bending, has no heat treatment hardening phenomenon (using temperature-196℃ ~ 800℃), and is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation, such as 300ml thermos flasks. But also has good processing performance and weldability, and is used for manufacturing plate heat exchangers, corrugated pipes, household products (class 1 and class 2 tableware, cabinets, indoor pipelines, 2 cup thermos flasks, boilers, bathtubs), auto parts (windshield wipers, silencers, molded products), medical appliances, building materials, chemistry, food industry, agriculture, ship parts, etc.
304 stainless steel is food grade stainless steel recognized by the state. Most usage requirements are to keep the original appearance of the building or master series vacuum bottle for a long time. When determining the type of stainless steel to be selected, the main considerations are the required aesthetic standards, the corrosivity of the local atmosphere and the cleaning system to be adopted. However, more and more other applications only seek structural integrity or impermeability. For example, roofs and side walls of industrial buildings and thermos flask with cup commonly used in life. In these applications, the owner's construction cost may be more important than aesthetics, and the surface may not be clean. The effect of using 304 stainless steel vacuum flask in dry indoor environment is quite good. However, in rural and urban areas, if you want to keep its appearance outdoors, you need to wash it frequently. In heavily polluted industrial areas and coastal areas, the surface of the steel flask online will be very dirty and even rust.
However, in order to obtain the aesthetic effect in outdoor environment, nickel-containing stainless steel should be used. Therefore, 304 stainless steel is widely used in construction, but it is best to use 316 stainless steel in industrial or marine atmosphere with severe erosion. People have fully realized the advantages of using stainless steel in structural applications, and several design criteria include 304 and 316 stainless steel. Stainless steel is manufactured in all standard metal shapes and sizes, and the most common one is thermos flask 2000ml, and there are many special shapes. The most commonly used products are made of thin plate and strip steel, and medium plate is also used to produce special products, such as hot rolled structural steel and extruded structural steel. There are also round, oval, square, rectangular and hexagonal welded pipes or seamless steel pipes and other products, including profiles, bars, wires and castings. It is also convenient to make cylindrical hot thermos for tea.
