The reason is that when alloying steel with chromium, the type of surface oxide is changed to be similar to that formed on pure chromium metal. This tightly adhered chromium rich oxide protects the surface from further oxidation. This oxide layer is very thin. Through it, you can see the natural luster of the steel surface, which makes the stainless steel have a unique surface. Moreover, if the surface layer is damaged, the steel surface will react with the atmosphere to repair itself, re form this passive film and continue its protective effect.Shape, stress, temperature and metal flow of forgings and dies.

When installing and welding the fixed port of stainless steel pipe, it is difficult to vent on the inner side, and some sides are easy to be blocked. In this case, water-soluble paper + blocking plate can be used for blocking. That is, the easy to vent and good side can be blocked with blocking plate, the difficult to vent and bad blocking plate side can be blocked with water-soluble paper, and the weld on the outer side can be blocked with adhesive tape (see Table ) .Information recommendation,The recrystallization temperature changes with the shape variable. When the shape variable is %, the recrystallization temperature drops to ℃, and the recrystallization annealing temperature of cold deformed austenitic stainless steel is ~ ℃. At ℃, it needs to be kept warm for h, fully burned at ℃, and then water-cooled.. Distinguish between L and L. There are two kinds of commonly used stainless steel l (or corresponding to the German / European standard l, the main difference in chemical composition between L and is that L contains Mo, and it is generally recognized that has better corrosion resistance than in high temperature environment. Therefore, engineers generally choose L parts in high temperature environment. However, there is no absolute thing. In concentrated environment, L should not be used at any higher temperature! No However, this is a big problem. People who study mechanics have all studied threads. Remember a black solid agent that needs to be applied to prevent threads from biting under high temperature: molybdenum disulfide (MOS), from which two conclusions are drawn: No: [] Mo is indeed a high resistance material (know what crucible gold is melted in? Molybdenum crucible!). [] : molybdenum can easily react with high valence sulfur ions to form sulfide. Therefore, no stainless steel is super corrosion resistant. In the final analysis, stainless steel is a steel with more impurities (but these impurities are more corrosion resistant than steel). If it is steel, and there is a large demand for building water supply pipes. According to the 'Ninth Five Year Plan' of construction and the outline of long-term objectives in , the demand for each pipe is ~ km from to , including km of cold and hot water pipes in residential construction areas. Some people believe that the development of stainless steel water pipes is of great significance to improve the grade of modern urban buildings.Nuevitas,The bright nickel layer on the stainless steel pipe is a silver white metal with slight yellow light. Its hardness is higher than that of copper, zinc, tin, cadmium, but lower than that of chromium and rhodium. Bright nickel has high chemical stability in air and good stability to alkali. Using Brightener on stainless steel pipe, bright nickel can be directly plated without polishing, so as to improve the hardness, wear resistance and leveling of the surface, and avoid the corrosion of potential difference between stainless steel pipe and other bright nickel. After using bright nickel solution for a period of time, due to the of brightenerAfter that, the second widely used steel is mainly used in food industry, pharmaceutical industry and surgical equipment. Adding molybdenum makes it obtain a special corrosion-resistant structure. Because it has better chloride corrosion resistance than stainless steel pipe, it is also used as & ldquo; marine steel & rdquo;. SS is usually used in nuclear fuel recovery devices. Grade stainless steel Steel pipes usually also meet this application level.Stabilization treatment. Generally, the steel is heated to ~ ℃ for heat preservation and air cooling.
