ASTM B815 is a standard specification for cobalt-chromium-nickel-molybdenum-tungsten alloy (UNS R31233) rods, and the following is a detailed breakdown of the standard: 1. Overview of the standard Standard number: ASTM B815 Scope of application: This standard covers rods of cobalt-chromium-nickel-molybdenum-tungsten alloy UNS R31233 for wear applications and general corrosion services. Second, the main requirements Dimensions and tolerances: The ASTM B815 standard specifies the size range and tolerance requirements for rods. The rod diameters range from 3/16″ to 3 1/2″, and the specific dimensions and tolerances depend on the diameter of the rod and the processing method (hot or cold worked). Processing and heat treatment: The processing methods of rods include hot working and cold working. The hot-worked rods need to be solution annealed to eliminate internal stresses and improve the uniformity of the material. Cold-worked rods may need to be pickled or mechanically descaled. Surface quality: The surface of the rod should be smooth, free of cracks, inclusions and other defects. At the same time, the standard also stipulates the packaging, transportation and storage requirements of rods to ensure their quality and safety during production and use. Third, the field of application Abrasion applications: UNS R31233 alloy rods have excellent wear resistance and are suitable for the manufacture of parts in various abrasive environments, such as plating rollers, chemical nozzles, etc. Corrosion service: The alloy also has good corrosion resistance and is able to resist the erosion of a variety of corrosive media. As a result, it is also widely used in areas where corrosion resistance is required, such as biomedical devices, valves, pumps, and nozzles. IV. Conclusions ASTM B815 Cobalt-Chromium-Nickel-Molybdenum-Tungsten Alloy (UNS R31233) rod is an alloy material with unique properties and a wide range of applications. The standard provides comprehensive specifications and requirements for its production and use, ensuring that the quality and performance of the material meets the needs of various applications.Huanickel?related?products?strictly?implement?this?standard.?For?more?information?about?the?standard?and?the?corresponding?product?information,[email protected] |
