The characteristics of stainless steel plate are strong corrosion resistance, high mechanical properties and high density. 1. Strong corrosion resistance: stainless steel plate is also called super austenitic stainless steel. It is a kind of stainless steel plate with very low carbon content. It has good corrosion resistance even in dilute sulfuric acid. The content of chromium, nickel and molybdenum, and the addition of copper elements, can effectively reduce the susceptibility to stress corrosion in chloride-rich environments. 2. Mechanical properties: As mentioned above, the stainless steel plate is a highly alloyed austenitic stainless steel with very low carbon content, so the minimum value of the mechanical properties of the stainless steel plate at room temperature is as follows. 3. High density: The characteristic point of high density of stainless steel plate is that compared with other austenitic stainless steel, the density of stainless steel plate is 8.24g/cm3.The metal can react with oxygen in the atmosphere to form an oxide film on the surface. The iron oxide formed on ordinary carbon steel will continue to oxidize, expanding the corrosion and eventually forming holes. This can be done using paint or an oxidation-resistant metal plating to protect the surface of carbon steel, but this coating is only a thin film. If the coating is damaged, the steel underneath begins to rust again. Whether the stainless steel tube is corroded is related to the chromium content in the steel. When the chromium content in the steel reaches 12%, the surface of the stainless steel tube generates a layer of passivation and dense chromium rich oxide to protect the surface and prevent further reoxidation. This oxide layer is extremely thin, through which the natural sheen of the steel surface can be seen, giving stainless steel a unique surface. If the chromium film is damaged once, the chromium in the steel and the oxygen in the atmosphere to regenerate the passivation film, continue to play a protective role. In some special environments, stainless steel will also appear some local corrosion and failure, but stainless steel and carbon steel is different, will not appear uniform corrosion and failure, so the corrosion allowance for stainless steel tube is meaningless.

1. Austenitic stainless steel Austenitic stainless steel refers to stainless steel with austenitic structure at room temperature. When the steel contains about 18% Cr, 8%~25% Ni, and about 0.1% C, it has a stable austenite structure. Austenitic chromium-nickel stainless steel includes the well-known 18Cr-8Ni steel and high Cr-Ni series steel developed on this basis by increasing the content of Cr and Ni and adding Mo, Cu, Si, Nb, Ti and other elements. Austenitic stainless steel is non-magnetic and has high toughness and plasticity, but its strength is low. It is impossible to strengthen it through phase transformation. It can only be strengthened through cold working. For example, adding S, Ca, Se, Te and other elements, it has good Machinability. 2. Ferritic stainless steel Ferritic stainless steel (400 series) has a chromium content of 15% to 30% and has a body-centered cubic crystal structure. This kind of steel generally does not contain nickel, and sometimes also contains a small amount of Mo, Ti, Nb and other elements. This kind of steel has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance, and excellent stress corrosion resistance. , Parts corroded by water vapor, water and oxidizing acid. The price of ferritic stainless steel is not only relatively low and stable, but also has many unique features and advantages. It has been proved that ferritic stainless steel is an extremely high-quality stainless steel in many applications that were originally considered to be only austenitic stainless steel (300 series). Excellent alternative material, ferritic stainless steel does not contain nickel, the main elements are chromium (>10%) and iron, chromium is a particularly corrosion-resistant element of stainless steel, and its price is relatively stable. 3. Duplex stainless steel Duplex Stainless Steel (DSS for short) refers to stainless steel with about 50% of ferrite and 50% of austenite, and generally less than 30% of the content of the less phase. In the case of low C content, the Cr content is 18%~28%, and the Ni content is 3%~10%. Some steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N. This type of steel has the characteristics of both austenitic and ferritic stainless steels. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance. The 475 ℃ brittleness and high thermal conductivity of element stainless steel have the characteristics of superplasticity. Compared with austenitic stainless steel, it has high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel-saving stainless steel. 4. Precipitation hardening stainless steel Precipitation hardening stainless steel refers to the addition of different types and quantities of strengthening elements on the basis of the chemical composition of stainless steel, and different types and quantities of carbides, nitrides, carbonitrides and intermetallic compounds are precipitated through the precipitation hardening process. , a type of high-strength stainless steel that not only improves the strength of the steel but also maintains sufficient toughness, referred to as PH steel. 5. Martensitic stainless steel High strength, but poor plasticity and weldability. The commonly used grades of martensitic stainless steel are 1Cr13, 3Cr13, etc. Due to the high carbon content, it has high strength, hardness and wear resistance, but the corrosion resistance is slightly worse, and it is used for high mechanical properties and corrosion resistance. Some general parts are required, such as springs, turbine blades, hydraulic valves, etc. This type of steel is used after quenching and tempering. Annealing is required after forging and stamping.
