There are three main reasons for oxidation of stainless steel: production process, which is one of the reasons for oxidation of steel products. In terms of production process and product characteristics, forming a thin oxide film on the product surface is the basic process to avoid oxidation, and it is also one of the main characteristics of steel products different from other steel products. It is specialized in products, renewable resources business and business package Including: stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe. However, when the oxide film is incomplete and discontinuous due to insufficient or negligent production process, the oxygen in the air will directly react with some elements in the product, resulting in the appearance of oxidation of the product.During welding, the process of ventilation in advance and gas stop behind shall be adopted, and the adhesive cloth on the outside shall be torn off while welding. Because the blocking plate is composed of rubber and white iron sheet it is not easy to be damaged, so this welding can well ensure that the inner side of the weld is filled with argon and its purity, so as to effectively ensure that the metal on the inner side of the weld is not oxidized and ensure the quality of weld backing welding.Bougado,HL polishing with appropriate particle size abrasive material to make the surface show continuous grinding lines.Austenitic stainless steel is generally used for manufacturing and manufacturing chemical equipment components, low-temperature equipment components in refrigeration industry, and can be used as stainless steel spring and clock spring after deformation strengthening.Satun,Hardness stainless steel pipes are usually measured by Brinell, the national economy has achieved rapid growth, and a large number of urban houses, public buildings and tourism facilities have been built, which puts forward new requirements for hot water supply and domestic water supply. In particular, people pay more and more attention to the problem of water quality, and the requirements are also increasing. Galvanized steel pipe, a common pipe, will gradually withdraw from the historical stage under the influence of relevant countries because of its corrosivity. Plastic pipe, composite pipe and copper pipe have become common pipes in the pipeline system. However, under certain circumstances, stainless steel pipe has more advantages, especially the stainless steel pipe with wall thickness of only . ~ mm. In high-quality drinking water system, hot water system and water supply system that puts safety and sanitation first, it has the characteristics of safety, reliability, sanitation, environmental protection, economy and applicability. It has been proved by engineering practice at home and abroad that it is one of the new, energy-saving and environmental protection pipes with good comprehensive performance of water supply system. It is also a very competitive water supply pipe, which will play an incomparable role in improving water quality and people's living standards.

Continuous casting shall be adopted for stainless steel pipe fittings, so as to improve the comprehensive yield, and cooperate with out of furnace refining, which significantly improves the production efficiency omits the blank opening process and saves a lot of energy consumption.It has lower linear coefficient than austenitic stainless steel and is close to carbon steel. It is suitable for connection with carbon steel and has important engineering significance, such as the production of composite plate or lining.Solution treatment. The main purpose of water quenching after heating the steel to ~ ℃ is to dissolve the carbide in austenite and keep this state to room temperature,BougadoStainless steel plate suction cup, so that the corrosion resistance of the steel will be greatly improved. As mentioned above, in order to prevent intergranular corrosion solid solution treatment is usually used to dissolve CrC in austenite and then cool rapidly. Air cooling can be adopted for parts, and water cooling is generally adopted.Total quality assurance,Clamping connection steps: cut off the pipe according to the required length. When breaking the pipe, it shall not be too large to prevent the pipe from being out of round.Application field: launch the market plan of stainless steel pipe in the target market of new products, such as stainless steel kitchen equipment.There are mechanical, it is not easy to remove the scale on the surface and make the surface highly clear and flat. Generally, the removal of the scale of stainless steel pipe should be carried out in two steps, the first step is pretreatment and the second step is ash removal.

Therefore,Bougado321 stainless steel strip,BougadoStainless steel high pressure pipe, the field with high utilization rate of stainless steel with high competitiveness and comprehensive quality will also be an important part of the plan.demand, the deformation energy is small. In low temperature environment, the phenomenon of reduced elongation and area shrinkage is called low temperature embrittlement. It is mostly produced on the body centered cubic structure of ferrite series.The corrosion resistance of duplex stainless steel, is better than that of ordinary l austenitic stainless steel, while super duplex stainless steel has very high corrosion resistance. In some media, such as acetic acid and formic acid, it can even replace high alloy austenitic stainless steel and even corrosion resistant alloy.When using this method, it should be noted that the water-soluble paper should be double-layer and must be pasted well, otherwise it is easy to cause damage and fall off of the water-soluble paper, resulting in loss of argon protection of the inner weld and oxidation, resulting in cutting of the weld junction and re welding, which can not ensure the welding quality and seriously affect the construction period. Therefore, the water-soluble paper should be strictly checked and pasted before welding.Bougado,Model & mdash; Cheap model (British and American), usually used as automobile exhaust pipe, is ferritic stainless steel (chromium steel).Model & mdash; Martensite (high strength chromium steel), good wear resistance and poor corrosion resistance.Stainless steel is usually divided into stainless steel pipe, stainless steel pipe and ferritic stainless steel according to the matrix structure. Chromium content % ~ %. Its corrosion resistance toughness and weldability increase with the increase of chromium content, and its chloride stress corrosion resistance is better than other kinds of stainless steel.
