What are the relevant international standards and norms for free forging?
The relevant international standards and specifications of free forging mainly include the following aspects: ISO and ASTM standards: The International Organization for Standardization (ISO) and the American Society for Materials and Testing (ASTM) have issued a series of standards involving free forging. Among them, the ISO 6932 and ASTM A668 standards cover the general requirements and technical specifications of free forgings, including materials, dimensions, tolerances, mechanical properties, etc. DIN Standards: The German National Organization for Standardization (DIN) has also published a series of standards related to free forgings, such as DIN 50401 and DIN 50049. These standards specify the quality requirements, inspection methods and mechanical properties of free forgings. GB Standard: China National Organization for Standardization (GB) has issued a number of national standards related to free forgings, such as GB/T 5224 and GB/T 3077. These standards mainly involve the material classification, performance requirements, chemical composition, heat treatment and other content of free forgings. ASME Standards: The American Society of Mechanical Engineers (ASME) has published a series of standards for free forgings, such as ASME B16.5 and ASME B16.47. These standards mainly relate to the application requirements and design specifications of free forgings in the fields of pipe, valve and flange connection. In addition, there are some International industry associations and organizations have developed specifications and standards related to free forgings, such as the European Aerospace and Space Materials Organization (EUROMAT), the American Aerospace Materials Association (ASM International) and so on. It is important to note that the specific standards and norms may vary by country, region and industry. Therefore, in practical applications, the corresponding standards and norms should be selected according to the requirements of the relevant regions and industries.
