Series & mdash; Martensitic precipitation hardening stainless steel.Steady state creep accelerated oxidation of stainless steel pipe during low cycle fatigue test in air environment. Obvious oxidation will occur in stainless steel pipe. Previous studies have shown that the time required for oxygen in air to diffuse to the fatigue crack tip is about the order of magnitude, and the biochemical reaction time between oxygen and fresh metal is longer than that of oxygen, about . seconds, which leads to high temperature air When the low cycle fatigue test is carried out in the gas environment, the oxygen content at the fatigue crack tip of the stainless steel pipe sample is always saturated, and the excess oxygen can diffuse to the base, resulting in the weakening of the bonding of the base metal atoms, increasing the embrittlement tendency of the material, and accelerating the expansion and growth of the crack. At the same time of low cycle fatigue, high temperature will also cause creep deformation of the stainless steel pipe, High temperature provides additional energy for the accelerated diffusion of atoms. When there are defects in the material, such as holes and voids the atomic diffusion becomes easy, and 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 voids, such as holes and voids Surrounding atomIn the building water supply pipe system, due to the end of the glorious history of galvanized steel pipe, various new plastic pipes and composite pipes have developed rapidly, but various pipes still have some deficiencies in varying degrees, which are far from fully meeting the needs of water supply pipe system and the national requirements for drinking water and related water quality. Therefore, relevant experts: building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience, stainless steel pipe is recognized as one of the pipes with good comprehensive performance in metal pipe.management,The product quality advantages of continuous casting billet of stainless steel pipe fittings are mainly reflected in that the non grinding rate of the outer surface of the billet except the head and tail section has reached more than %, it is necessary to refine the molten steel, do a good job in the metallurgy of the ladle and tundish, accurately determine the molten steel temperature, and realize no oxidation casting Further reduce the inclusion content.Construction materials shall be prepared and delivered to the site according to the data scheme, architects have been using stainless steel to build cost-effective buildings. Many existing buildings fully illustrate the correctness of this choice. Some are very ornamental and shall be supplied according to the scheme.For more than years, such as the Chrysler Building in New York City. However, in many other applications the role of stainless steel is not so eye-catching, because stainless steel has more wear resistance and pressure resistance than other metal materials of the same thickness, it is the preferred material for designers when building sidewalks in places with large population flow.

Model & mdash; 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.Test conclusion,Production mode stainless steel pipe can be divided into seamless pipe and welded pipe according to the production mode. Seamless steel pipe can be divided into hot-rolled pipe, cold drawn pipe and pipe.
