if you need to know the specific value

Small, you can search the table on the Internet.It refers to the use of manual welding rods for welding. A electrode can be used for welding L stainless steel plate with mm thickness, and the intermediate layer needs to be cleaned during electrode welding.South end of the sea,The construction period is, so the welding shall be strictly checked and the water-soluble paper shall be pasted before welding.Ping.SireProducts have become a common category in people's daily life.Although the stainless steel plate is corrosion-resistant, it does not mean that the stainless steel will not be corroded. If the stainless steel plate is used and maintained improperly or the use environment is too bad, local oxidation corrosion will also occur.crniti, CrNiTi, etc. Duplex stainless steel has good weldability, no heat treatment is required after welding, and its tendency of intergranular corrosion and stress corrosion is also small. However, due to the high content of Cr, it must be moved, moved and moved for a long distance. If there is no bag, there will be scratches and scratches on the surface, which will affect the appearance of the surface.The welders should be specially trained and skilled before they can participate in welding. In Nanjing Yangba and foreign construction sites, we have successfully solved the problem that argon cannot be passed through the junction and repair port.The corrosion behavior and law of electroless plated PD sample on L stainless steel in medium and mixed acid medium were studied by polarization curve and electrochemical impedance spectroscopy (EIS). Its performance in these two typical non oxidizing acid media was evaluated. The results show that L stainless steelIndustry management,When water-soluble paper is used to block the ventilation, the ventilation pipe shall be pulled out quickly in the later sealing link,South end of the sea309S stainless steel, and the residual argon inside shall be used for protection, so as to quickly finish the bottom and seal the mouth.The best welding process parameters are selected, and the repeatability verification test is carried out. Finally, two welding processes meeting the phase ratio are obtained. In this paper, the mechanical properties and corrosion resistance of the welded joint of SAF duplex stainless steel pipe welded under good welding process parameters were testedOften used in Engineering

Stress relief treatment. Stress relief treatment is a heat treatment process to eliminate the residual stress of steel after cold working or welding. Generally, the heating temperature shall not exceed ℃, so as to avoid precipitation of chromium carbide and intergranular precipitationHigh quality brand,The mechanical performance and shape of concrete-filled steel tubular eccentric straight bar are similar in general,South end of the sea316 stainless steel, and its bearing capacity and stiffness are slightly higher than that of the corresponding eccentric straight bar Based on the finite element analysis software ABAQUS, a numerical model is established to analyze the mechanical characteristics of concrete-filled stainless steel tubular curved bar. The finite element analysis results are consistent with the test resultsIf the back side is blocked with blocking plate for ventilation protection (that is, when the stainless steel pipe with solid core welding wire is prefabricated, the welded junction can usually be rotated for welding, and ventilation is very easy. At this time blocking plate is usually used to block both sides of the welded junction in the pipe,South end of the sea444 professional stainless steel plate, and backing welding is carried out for ventilation protection (see table)Use flux coated welding wire (self shielded welding wire) for backing TIG welding.South end of the sea,YesThe product quality is greatly reduced. For example, when the chromium content of stainless steel pipe is insufficient, it will not only affect the corrosion resistance and formability of the product, but also have potential product quality and safety hazards when used in chemical, equipment and production industries; At the same time, it also affects the appearance and oxidation resistance of the product.The main way to prevent stress corrosion of austenitic stainless steel is to add SI ~ % and keep the content of N below .% from smelting. In addition, the content of impurities such as P, Sb, Bi and as shall be minimized. In addition, A-F dual phase steel can be selected, which corresponds to stress corrosion in Cl - and oh - media
