ASTM B672 is a standard specification for rods and wires of a nickel-iron-chromium-molybdenum-niobium-stabilized alloy (UNS N08700), and the following is a detailed breakdown of the standard: 1. Overview of the standard Standard number: ASTM B672 Second, the main requirements The ASTM B672 standard typically contains the following: Chemical composition: The content range of nickel, iron, chromium, molybdenum, niobium and other elements in the alloy is specified to ensure that the performance of the alloy meets specific requirements. Mechanical properties: including tensile strength, yield strength, elongation and other mechanical property indicators, which reflect the bearing capacity and deformation capacity of the alloy under different conditions. Dimensions and tolerances: Requirements for diameter, length, dimensional tolerances, etc., of bars and wires are specified to ensure the interchangeability and consistency of products. Surface quality: The surface finish, cracks, inclusions and other defects of the product are limited to ensure the appearance quality and internal quality of the product. Inspection and testing: The inspection methods and testing procedures of the products are specified, including chemical composition analysis, mechanical property testing, non-destructive testing, etc., to ensure that the products meet the requirements of the standard. Packaging and labeling: Specifies the packaging method and labeling requirements of the product to facilitate the transportation, storage and traceability of the product. Third, the field of application Nickel-iron-chromium-molybdenum-niobium stabilized alloy (UNS N08700) is widely used in many fields due to its excellent corrosion resistance and mechanical properties, such as: Chemicals and petroleum natural gas Marine Engineering nuclear industry, etc. 4. Precautions When using the ASTM B672 standard, care should be taken to select the version that applies to the specific product and carefully read the content of the standard to understand the requirements and constraints. When purchasing and using nickel-iron-chromium-molybdenum-niobium stabilized alloy (UNS N08700) rods and wires, suppliers should be required to provide certificates of conformity and inspection reports that meet the requirements of the standard. In the process of processing and use, the relevant safety operation procedures and process requirements should be complied with to ensure the quality and safety of the product. In summary, ASTM B672 is an important standard specification for nickel-iron-chromium-molybdenum-niobium-stabilized alloy (UNS N08700) rods and wires, which is of great significance for ensuring product quality and performance.
