 Many things we used in our life are made by  stainless steel pipe , such as doors, windows etc.. And we know that they are need to be polished during production. Generally, there are three different types of polishing methods, which are related to their respective advantages and operating steps: 1. Mechanical polishing: The advantage of this method is that the flatness of the product after processing is better, and the brightness is higher. 2. Chemical polishing: its advantage is that the investment in processing equipment is smaller, and the production efficiency is higher, and the anti-corrosion performance is good. 3. Electrochemical polishing: It has the advantages of long mirror gloss, stable process, less pollution, low cost and good corrosion resistance.

  1. die forging  　　   For socket welding and threaded tees, crosses, elbows and other small-size pipe fittings, its shape is more complicated, and die forging can be used. The blanks used in this process should be rolled profiles. If  stainless steel plates  are used as raw materials, the rolled profiles of steel ingots must be prepared first. After being heated, the blank is put into the die for forging, and the pressure makes the metal flow to fill the cavity; if the blank after die forging has flash, it will go through the step of flushing the remaining material to complete all the forging work.  　 2. free forging  　　   For special-shaped pipe fittings or stainless steel plates that are not suitable for die forging, they can be manufactured by free forging process. Free forging should forge the general shape of the pipe.  　　 3.cutting  For some cylindrical stainless steel plates, rods or thick-walled pipes can be directly cut and pro...

  1.       Mechanical polishing: The advantage of this method is actually that the flatness of the product after processing is better, and the brightness is also higher.  　　 2.       Chemical polishing: Its advantage is that the investment in processing equipment is relatively small, and the production efficiency is relatively high and the corrosion resistance is good. 3.       Electrochemical polishing: It has the advantages of long mirror gloss, stable process, less pollution, low cost and good corrosion resistance.   HCADTO Stainless Steel Co., Ltd.   the Stainless Steel Division of ADTO GROUP, specializes in manufacturing  stainless steel pipes ,  stainless steel angle bar, flat bar, round bar, square bar, hexagonal bar and channel bar in various grades and sizes.

The  stainless steel angle bar  is widely used in auto parts, elevators, kitchen equipment, pressure vessels and other fields, and is well received by users. The key to application in future development is environmental protection and long life.  　   In terms of environmental protection, firstly, from the perspective of atmospheric environmental protection, the demand for heat-resistant, high-temperature corrosion-resistant stainless steel angle bar for high-temperature waste incineration devices, LNG power generation devices, and high-efficiency power generation devices that use coal to suppress the generation of dioxin will increase.   Regarding long life, the use of stainless steel angle bar is increasing in existing bridges, highways, tunnels and other facilities in Europe, and this trend is expected to spread all over the world. In addition, the lifespan of general residential buildings in Japan is particularly short of 20-30 years, and the disposal of wast...

The current quality of life has also begun to change with the changes of the times. The   stainless steel angle bar   i s   a product that meets the needs of the development of the times in today's society. It has obvious effects in the process of application, and it can make progress and promotion during application, which indeed provides convenient production conditions for the production environment. With the rapid development of the construction industry, in the face of more and more manufacturers who have made further improvements in the application of products, the use of stainless steel angle bar to help is still outstanding. The application of this bar material can make the modification of the length of the building material smooth, and the hardness of the bar material is strong, so the degree of wear on the surface of the building material will be reduced during the grinding process, so as to ensure that the manufacturer can get further in the technical processin...

  1 The selection of   stainless steel plates   should consider the operating conditions, such as manual or automatic operation, the performance and type of the hot press, and the quality requirements of the pressed material such as hardness and gloss. 2 Economic calculations must also be considered. Each time a new steel plate is polished, it is required to produce a low-quality decorative plate.  3 In addition, when selecting the most reasonable thickness of the steel plate, its service time, quality and rigidity should be considered, and the strength requirements of the plate under compression; heat conduction performance; pressure distribution, and the width of the plate should be considered. If the thickness of the steel plate is not enough, it is easy to bend, which will affect the production of decorative panels. If the thickness is too large, the steel plate is too heavy, which not only increases the cost of the steel plate, but also brings unnecessary diffic...

The use of   stainless steel pipes   is now more and more widely used. Because of its good corrosion resistance, it has played a vital role in engineering construction. During the production process, we need to perform solid solution treatment on stainless steel pipes. The main purpose is to obtain certain Martensite increases the hardness of the product. Let's look at the solution treatment of stainless steel pipes below: (1) Intermediate aging method heats to (760±15) ℃ after solution treatment, and keeps it for 90 min. Because Cr23C6 carbide precipitates from austenite, it reduces the content of carbon and alloying elements in the austenitic 904L stainless steel tube , The Ms point is raised to 70℃ and then cooled to room temperature to obtain martensite+αferrite+retained austenite structure. The retained austenite is decomposed after aging at 510℃.  (2) After high temperature adjustment and cryogenic treatment, heat to 950 ℃  and hold for 90min after solid soluti...
