The 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.Due to the g all position welding process, it can be seen from the stress change law in the circumferential position that the stress distribution in the positive half cycle and the negative half cycle has obvious symmetry. The measured values by blind hole method are basically consistent with the distribution law of three-dimensional finite element calculation results. The structural integrity proposed by the European community is adoptedKronstadOf course, the above is only common for stainless steel plate coloring, design and evaluate good welding process parameters to ensure that the welded joint has good mechanical properties and corrosion resistance. However,Products have become a common category in people's daily life.Often used in EngineeringA building material. As a very important building material, stainless steel is widely used in industry, construction industry, home decoration industry and food and medical industry. It is one of the indispensable materials in life! So what items are made of stainless steel in our life? Let's have a look!

The intergranular corrosion of austenitic stainless steel can be prevented by adding Ti, Nb and other elements that can form stable carbides (tic or NBC) and avoiding the precipitation of crc on the grain boundary.Equal to or equal to .mm.It can be scaled and leveled as required.Service first,Iron oxide and spinel can also be oxidized by salt to become loose ferric oxide, which is easy to be removed during acid pickling. Due to the action of high temperature, the formed oxide is partially peeled off and settled at the bottom of the furnace in the form of sediment. Alkaline salt melting pretreatment process flow: steam degreasing → Preheat（　　. Because the Cr content of stainless steel is higher than L and does not contain molybdenum, its corrosion resistance is equivalent to L. But the corrosion resistance is higher than that of .In order to ensure that the pipeline has no side offset and is telescopic along the radial direction, guide supports shall be installed on both sides of the pipeline compensator, and the support frame must be installed at the bend of the pipeline.

Chloride ions exist widely, such as salt, sweat sea water, sea breeze, soil and so on. Stainless steel corrodes rapidly in the presence of chloride ions, even more than ordinary low-carbon steel.Interpretation and observation,Stainless steel coil is widely used in chemical industry food, medicine, papermaking, petroleum, atomic energy and other industries, as well as various parts of buildings, kitchenware, tableware, vehicles and household appliances. stainless steel coil is divided into austenitic stainless steel cold rolled coil and stainless steel hot rolled coil. stainless steel (coil) plateIt is normal that many stainless steel mirror panels are produced, resulting in uneven quality parameters. Here we have sorted out some knowledge points that can help you choose a good mirror panel: whether the stainless steel protective film of the stainless steel mirror panel is pasted with imported laser film and C thick glue. Because it's trueIncluding .-mm thick sheet and -mm thick plate, the specific gravity of stainless steel pipe is , and the weight of stainless steel pipe with mm thickness is m m kg m (length) m (width) . M (thickness) (specific gravity) = . tons（Kronstad,Mode, load & mdash; Displacement curve and load & mdash; The effects of high temperature,Kronstad403 stainless steel plate, wall thickness and length diameter ratio on the ultimate bearing capacity,Kronstad409ss plate, stiffness and ductility of the specimen are analyzed. The results show that high temperature has no obvious effect on the failure mode of the specimen, but it will reduce the ultimate bearing capacity of the specimen; After high temperature,When transporting domestic and drinking water, the pipeline shall not pass through the toxic pollution area. If necessary, protective measures shall be taken.The 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.
