Benefits of 304 stainless steel:
1, environmental health: put an end to the red water, blue green water, and hidden water problems, no smell, no harmful substances precipitation to maintain pure water, no lead harmless to human health.
2, wear resistance: beautiful surface, clean, bright, durable, no scratches, never rust, never break.
3, low temperature resistance: kitchen bathroom stainless steel water pipe, faucet Angle valve never break.
4, thermal expansion performance and heat preservation performance is excellent: stainless steel tube with slow thermal expansion and contraction, good heat preservation performance.
5, authority certification: stainless steel metal element precipitation amount is 5% lower than WHO and European drinking water regulation standard value.
304 stainless steel: is a common stainless steel material, density of 7.93g/cm3, the industry is also known as 18/8 stainless steel. High temperature resistance of 800 degrees, with good processing performance, high toughness, widely used in industry and furniture decoration industry and food and medical industry.
304 is a universal stainless steel, which is widely used in the manufacture of equipment and parts requiring good comprehensive properties (corrosion resistance and formability). To maintain the corrosion resistance inherent in stainless steel, the steel must contain at least 18% chromium and at least 8% nickel.
Other applications of 304 stainless steel are increasingly just looking for structural integrity or impermeability. For example, 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 works well in dry indoor environment. However, in rural and urban areas to maintain their appearance outdoors, they need to be cleaned frequently. In heavily polluted industrial and coastal areas, the surface can be very dirty and even rust.
However, in order to achieve aesthetic effect in outdoor environment, it is necessary to use nickel stainless steel. Therefore, 304 stainless steel is widely used in curtain wall, side wall, roof and other building purposes, but in the serious erosion of industrial or Marine atmosphere, it is best to use 316 stainless steel. Stainless steel sliding door, people already realized the superiority that uses stainless steel in structural application adequately.
Several design criteria include 304 and 316 stainless steel. Because "duplex" stainless steel 2205 combines excellent atmospheric corrosion resistance with high tensile strength and elastic limit strength, it is included in the European standard. In fact, stainless steel is manufactured in all standard metal shapes and sizes, and there are many special shapes as well.
The most common products are made of sheet and strip steel, and special products are also made of medium thick plates, for example, hot-rolled structural sections and extruded structural sections. There are also round, oval, square, rectangular and hexagonal welded or seamless steel tubes and other forms of products, including sections, bars, wires and castings.
