201 Stainless steel plate201 stainless steel plate is a common chrome-nickel stainless steel plate with the following characteristics:
Corrosion resistance: 201 stainless steel plate has good corrosion resistance in some media, such as atmosphere, water, weak acid, alkali and so on. In corrosive media, due to the chemical stability of chromel, 201 stainless steel can resist oxidation and corrosion, thereby extending the service life.
Good processing performance: 201 stainless steel plate has good plasticity and ductility, easy to cold and hot processing. This makes it suitable for the manufacture of various shapes, such as sheet, plate, bar, etc.
Beautiful surface: Because 201 stainless steel plate has a smooth surface, not easy to rust, easy to clean and maintain, it is often used to make decorations and furniture.
Good welding performance: 201 stainless steel plate has good welding performance, easy to carry out arc welding, resistance welding, brazing and other operations. This gives it a wide range of applications in the manufacturing process.
However, it should be noted that the corrosion resistance of 201 stainless steel plate is relatively weak, especially in corrosive media such as strong acids and alkali. In addition, the cost of 201 stainless steel plate is relatively low, so it is widely used in some occasions with low requirements.

The main chemical components of Monel alloy plates are nickel and copper, which contain up to 67% nickel, 28% copper and other elements such as iron, manganese, carbon and silicon. Its melting point is 1315-1350℃, and the maximum use temperature is 538℃.
In addition, Monel alloy plates also have good mechanical properties and processing properties, can be cold working to enhance hardness, but also through heat treatment to increase strength. Its hardness depends on the heat treatment state and use conditions, and its hardness and strength can be enhanced by heat treatment and cold working. - Stainless steel coilStainless steel coil is a sheet made of stainless steel material, and the rolled product is not easy to oxidize, corrosion resistance and other characteristics, which is widely used in construction, manufacturing and other fields.
The raw material of stainless steel coil is cold-rolled stainless steel plate, which is rolled and has a more precise thickness and smoother surface than hot-rolled stainless steel plate, while having better mechanical properties and processing properties.
There are many kinds of stainless steel rolls, the common ones are 201, 303, 304, 304L, 321, 316, 316L, 309S, 310S, 2520, 904, 904L biphase steel series S32205
S32507 and so on. - Carbon steel coilCarbon steel coil is a coil made of carbon steel, usually made of low carbon steel plate, the carbon content is between 0.0218% and 2.11%. The strength and hardness of this steel mainly depend on the content of alloying elements, such as manganese, silicon and phosphorus. The specifications and models of carbon steel rolls are also important factors in the selection, and the appropriate specifications and models need to be selected according to the actual needs.
Carbon steel coil has good wear resistance, corrosion resistance and fatigue resistance, and is widely used in various heavy industrial machinery and equipment wear-resistant parts, such as mining, metallurgy, coal, power and other industries. At the same time, it can also be used to manufacture various wear resistant appliances and wear resistant repair. - 6061 Aluminum coil6061 aluminum coil is a kind of aluminum alloy material, which has good corrosion resistance and weldability, and is widely used in various fields.
The strength of 6061 aluminum coil is high, and higher strength can be obtained after heat treatment, while still maintaining good plasticity and toughness. Its corrosion resistance is also relatively good, can be used in harsh environments for a long time. In addition, the 6061 aluminum coil also has good weldable properties, which is convenient for processing and manufacturing.
Due to these excellent properties, 6061 aluminum coils are widely used in various fields, such as mobile phone shell materials, automobile wheels, pull rod boxes, 3C products, etc. At the same time, it is also often used in the manufacture of various industrial structural parts requiring a certain strength and high antimicrobial corrosion. In the field of rail vehicles, 6061 aluminum coils are used to manufacture interior and exterior panels, floors, compartment panels and other parts.

- Steel common defect types to reduce defect production methodsAt present there are seven kinds of common defects: steel surface crack, scratch, scratch), folding, handle, scarring (lap) the burr, welding scar, end. Steel plant operators are the reasons causing common defects, defect in steel and processing methods have deep understanding, here is not introduced in detail. Focus on how to monitor the defect information.
For defect detection in a timely manner, the need for on-line detection, contour measurement instrument as online flaw detector is a good choice, it can detect most of the surface defects, folding, warping, pits, grooves, lugs, crack, scratch, scratch) such defects can be detected and displayed.
Profile measuring instrument is "attorney" steel surface quality monitoring. Rolling production, through an automated measuring instrument, the defect of the real-time monitoring, don't pass any defect, for now, it can detect the defect information of 0.5 mm and above, and is a comprehensive no dead Angle of the cross section test, to detect the frequency of 4000 hz, transverse longitudinal blind area is small, don't pass steel defects.
Contour instrument to monitor the quality of cross section through, then form a high-resolution display complete surface, allowing the detection of local and periodic surface defects, and the change of the size of the rolled products.
Profile measuring instrument to help in the process of producing steel strengthen production quality control, so as not to appear a lot of incomplete, affect the economic benefits of enterprises. It takes on steel surface defect, measurement analysis of the surface defects in production, and the defects of rolling technology and to explore the influence of performance, increase the use of steel properties and the yield.
- Differences between Duplex Stainless Steel and Stainless Steel (Advantages and Disadvantages)In duplex stainless steel, the ferrite phase and austenite phase account for half in its hardened structure, and the minimum phase content may reach 30%. 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 both the characteristics of austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance, while maintaining iron 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.
Product Advantages
Compared with austenitic stainless steel, the disadvantages of duplex stainless steel are as follows:
(1) The universality and versatility of application are not as good as that of austenitic stainless steel. For example, its use temperature must be controlled below 250 °C.
(2) Its plasticity and toughness are lower than that of austenitic stainless steel, and its cold and hot working processes and forming properties are not as good as that of austenitic stainless steel.
(3) There is a medium temperature brittle zone, and it is necessary to strictly control the process system of heat treatment and welding to avoid the appearance of harmful phases and damage the performance.
Compared with ferritic stainless steel, the disadvantages of duplex stainless steel are as follows:
The content of alloying elements is high, the price is relatively high, and generally ferrite does not contain nickel.
