大口径航空厚壁结构无缝钢管,主要用于飞机起落架及与起落架相配套的地面液压装置。另外还可用于承受强度高的机械、传动器械的另部件和树件上。这些构件都在动载荷条件下工作,承受较大的冲击载荷,因此要求材质具有较高的强度和足够的韧性,而且还要有良好的耐磨性、焊接性和加工性能。具备这些性能的材质,其组织要纯洁,成份要均匀,综合机械性能要好,各向异性要较小。这样的材
Large-caliber aviation thick-walled seamless steel pipe, mainly used in aircraft landing gear and landing gear matching ground hydraulic device. In addition can also be used to withstand high strength machinery, transmission parts and other parts of the tree. These components are working under dynamic load conditions, bear a greater impact load, thus requiring material with high strength and sufficient toughness, but also have good wear resistance, weldability and processing performance. With these properties of the material, the organization should be pure, ingredients should be uniform, better overall mechanical properties, anisotropy to be smaller. Such material
