The power supply with vertical external characteristics is adopted， and the positive polarity is adopted in DC (the welding wire is connected to the negative pole).
8The linear expansion coefficient of austenitic stainless steel is lower than that of austenitic stainless steel， close to that of carbon steel， suitable for connection with carbon steel， and has important engineering significance， such as the production of composite plate or lining.

It is generally suitable for the welding of thin plates below mm， with the characteristics of beautiful weld formation and small welding deformation.
XMandurah — After that， the second widely used steel is mainly used in food industry and surgical equipment. Molybdenum is added to obtain a special corrosion-resistant structure. Because it has better chloride corrosion resistance than it， it is also made & ldquo; Marine Steel & rdquo; To use. SS is usually used in nuclear fuel recovery units. Grade stainless steel generally meets this application grade. [] Model & mdash; Except that the risk of weld corrosion of the material is reduced due to the addition of titanium other properties are similar.
TnWhen selecting stainless steel water supply pipe， carefully observe whether the surface of the pipe is shiny， damaged and crushed， and pay attention to whether the incision is neat. If these phenomena occur， they should be carefully considered.
The steel grades for JIS mechanical structures are: S + carbon content + letter code (CK)， in which the carbon content is represented by the intermediate value & times; ，Products Show the letter C: represents carbon， the carbon content of carbon coil sc is .-.%. The grades of silicon steel sheets in China and Japan are.
The compressive strength of duplex stainless steel alloy is twice that of austenitic stainless steel. Compared with L and L， the designer can reduce its weight. Alloy is especially suitable for & mdash; ° F/+° F temperature range， in strict cases (especially for welded structures)， it can also be used for lower temperatures. C≤ . Mn≤ Si≤ p≤ . S≤ .

AWindproof and ventilation. Where there is wind， please take measures to block the net， and take appropriate ventilation measures indoors.
PProfessional is kingThe cold rolled steel strip has good strength and yield ratio， and the hot rolled steel strip has good ductility and toughness.
cXThe oxygen content at the fatigue crack tip of the tube sample is always saturated， and the excess oxygen can diffuse into the matrix again， resulting in the weakening of the bonding of the matrix metal atoms，Products Show and accelerating the crack propagation and growth. At the same time of low cycle fatigue， such as holes and voids，Price of stainless steel plateBasic knowledge of speed atomic diffusion becomes easier. With the progress of low cycle fatigue， dislocations will be generated in the material under the action of stress， The slip and climb of dislocations interact with point defects to promote the aggregation of micropores and form large cavities. The atoms around holes and voids rearrange with time resulting in the continuous aggregation of holes， weakening the material， and finally forming macro cracks， resulting in the fracture of stainless steel pipe material. Compared with room temperature， high temperature promotes the accelerated oxidation of materials and the accelerated diffusion of atoms. Under the action of stress， the interaction between internal defects and dislocations can significantly reduce the low cycle fatigue performance of stainless steel tubes. The law of creep deformation of stainless steel pipe can be described by creep curve，tisco stainless steel sheet,taigang stainless steel sheet,stainless steel sheet,stainless steel coil,stainless steel strip,stainless steel tube-TISCO Stainless Steel Co.,Ltd which reflects the relationship between deformation and time under specific temperature and stress structure. The typical creep curve includes three stages: creep stage， with a gradually slowing creep rate; The second stage of creep: steady-state creep stage， which is an important stage when the strain hardening process and recovery process reach equilibrium; In the third stage of creep， the creep process accelerates until fracture.
The resistance， coefficient of linear expansion， thermal conductivity， quality， hot melt and magnetism of stainless steel pipe will change greatly at low temperature. Resistance， martensite can be formed when it is kept below MS point. The formation of martensite at low temperature makes the representative steel sus (Cr-Ni) of austenitic stainless steel non-magnetic at room temperature and magnetic at low temperature.
Shop around and choose affordable stainless steel water supply pipes. Compared with the prices of pipes sold by various companies， we should choose carefully and should not buy them at a low price. However， the transmission energy consumption of stainless steel pipe water supply pipe is low which saves the transmission cost， so the price will not be too expensive.

ZWhen the addition of chromium reaches %， the atmospheric corrosion resistance of steel increases significantly， but when the chromium content is higher， although the corrosion resistance can still be improved， it is not obvious. The reason is that when alloying steel with chromium， the type of surface oxide is changed to a surface oxide similar to that formed on pure chromium metal
The adhesion of stainless steel surface contains acid， alkali and salt substances (such as alkali water and lime water splashing on the decoration wall) causing local corrosion.
xThe linear expansion coefficient of austenitic stainless steel is lower than that of austenitic stainless steel， close to that of carbon steel， suitable for connection with carbon steel， and has important engineering significance， such as the production of composite plate or lining.
