Performance damage and possible solutions for stainless steel pipes after cold processing

In order to enhance the performance of the stainless steel pipe, usually use some cold processing technology, such as cold drawing, cold rolling, cold rolling, cold, cold, cold expansion distortion, but finally achieve effect, also will inevitably suffer some damage, these cold working process and welding processing, will damage the performance of the stainless steel pipe, especially corrosion or heat resistance.

There are five main reasons for the damage of stainless steel pipes. First of all, it will increase the micro defects and surface roughness of the lattice dislocation of the pipe material, and also induce martensite transformation and precipitation of carbides. For example, austenitic stainless steel presents a magnetic increasing phenomenon after cold working.

Secondly, the lattice dislocation or phase transition of stainless steel pipe will occur on the ...

Analysis of problems encountered in application of stainless steel bellows

Generally speaking, stainless steel bellows in the application may encounter internal leakage or leakage phenomenon, resulting in a lot of reasons, usually due to liquid medium containing solid impurities damage the sealing surface caused by. The causes of valve stem leakage are mainly related to valve structure, working environment and service mode.

The structural stem uses stainless steel bellows and packing double seal structure, bellows lining ring and outer lining ring welded into bellows components, and then with the stem and guide body welding, so as to block the medium through the valve stem leakage. The distance between the upper and lower of the valve rod moves upwards until the upper end of the flat key is contacted with the lower end of the lower packing. Because the lower packing is made of PTFE material, once the valve is over opened, the flat ...

Common chemical elements in stainless steel plate

There are more than 10 kinds of common elements in stainless steel plate. In addition to the basic element iron, the most important elements affecting the performance and microstructure of stainless steel plates are carbon, chromium, nickel, manganese, silicon, molybdenum, titanium, niobium, titanium, manganese, nitrogen, copper, cobalt and so on. When some elements coexist in the whole stainless steel, the influence of far is much more complex than when they exist independently, because not only to consider the elements of its function, but also pay attention to their effects caused by each other, so the performance of stainless steel is the sum of various elements affect the decision by the.

Chromium plays a decisive role in stainless steel, as long as the stainless steel contains a certain amount of chromium. This is because the addition of chromium to the ...

Introduction of mechanical properties and stamping process of stainless steel plate

Stainless steel plate can be used to make a lot of daily necessities, stainless steel processing technology is diverse, such as stamping, bending, shear folding, etc., this paper focuses on stamping process. The common stamping forming processes of stainless steel sheet include drawing process, bulging process, flanging process (including reaming) and bending process. The corresponding material properties are bulging forming performance, flanging formability, reaming formability and bending formability.
But before talking about the stamping process of stainless steel plate, the two factors that will affect the mechanical properties of stainless steel are also discussed. They are internal cause and external cause respectively. Internal causes are more important, that is, different chemical elements in stainless steel tissue, ... [more]

Problems encountered in welding thin wall stainless steel tubes

When welding thin wall stainless steel, the technical level requirements are very high, because in the welding of this kind of material, will face many problems, such as construction site problems, heat treatment problems, thermal expansion and cold contraction problems, the following to tell the solution to these problems.
First of all, the construction capacity, welding is a relatively strong professional activities, generally after welding can not be demolished, in the actual construction site for a long time, because it is necessary to change, resulting in very inconvenient. Because of the need for specialized equipment and argon arc welding of thin wall stainless steel tube, the thickness is very thin, there must be a high level of welders operation, but in the actual construction site personnel mobility, if ...
