304 stainless steel pipe description
Stainless Steel Pipe 304 Stainless Steel Pipe 304 Stainless Steel Seamless Pipe 304 Stainless Steel Welded Pipe
304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm ³； It is also called 18/8 stainless steel in the industry, which means that it contains more than 18% chromium and more than 8% nickel; It has high temperature resistance of 800 ℃, good processing performance and high toughness, and is widely used in industry, furniture decoration industry and food and medical industry. However, it should be noted that the content index of food grade 304 stainless steel is more strict than that of ordinary 304 stainless steel. For example, 304 stainless steel is basically defined internationally as mainly containing 18% - 20% chromium and 8% - 10% nickel, while food grade 304 stainless steel contains 18% chromium and 8% nickel, allowing fluctuations within a certain range, and limiting the content of various heavy metals.
In other words, 304 stainless steel is not necessarily food grade 304 stainless steel
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 properties; Stamping, bending and other hot workability are good, without heat treatment hardening (use temperature - 196 ℃~800 ℃). It 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. It has good processability and weldability. Plate heat exchanger, corrugated pipe, household goods (Class 1 and 2 tableware, cabinet, indoor pipeline, water heater, boiler, bathtub), auto parts (windshield wiper, muffler, molded products), medical appliances, building materials, chemistry, food industry, agriculture, ship parts, etc. 304 stainless steel with strictly controlled content can also be called food grade 304 stainless steel
Most use requirements are to maintain the original appearance of
the building 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 are just seeking structural integrity or
impermeability. For example, roofs and side walls of industrial
buildings. In these applications, the construction cost of the
owner 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 maintain its appearance outdoors, you need to wash it
frequently. In heavily polluted industrial areas and coastal areas,
the surface will be very dirty, or even rust.
However, in order to obtain the aesthetic effect in the outdoor
environment, nickel containing stainless steel is required.
Therefore, 304 stainless steel is widely used for curtain walls,
side walls, roofs and other building purposes. However, in the
highly corrosive industrial or marine atmosphere, 316 stainless
steel is preferred. Stainless steel sliding door, people have fully
realized the advantages of using stainless steel in structural
applications. Several design criteria include 304 and 316 stainless
steels. Because the "duplex" stainless steel 2205 has integrated
good atmospheric corrosion resistance with high tensile strength
and elastic limit strength, the European Code also includes this
steel. Product shape In fact, stainless steel is produced in full
standard metal shape and size, and there are many special shapes.
The most commonly used products are made of sheet and strip steel,
and special products are also produced from medium and thick
plates, such as hot-rolled structural steel and extruded structural
steel. In addition, there are also round, oval, square, rectangular
and hexagonal welded pipes or seamless steel pipes and other forms
of products, including profiles, bars, wires and castings.
