GB/T 4008-2024 in English

The GB/T 4008-2024 standard, titled "Ferromanganese-Silicon Alloys," is a national standard issued by the Standardization Administration of China (SAC). Released on June 29, 2024, and set to take effect on January 1, 2025, this standard specifies the technical requirements, testing methods, inspection rules, packaging, marking, storage, transportation, and quality certificates for ferromanganese-silicon alloys. Ferromanganese-silicon alloys are widely used in the steelmaking industry as deoxidizers and alloying agents to improve the mechanical properties and corrosion resistance of steel products.

The standard outlines the chemical composition, physical properties, and permissible deviations for different grades of ferromanganese-silicon alloys. It also provides detailed guidelines for sampling and sample preparation to ensure the accuracy of test results. Additionally, the standard emphasizes the importance of proper packaging and labeling to prevent contamination and ensure the safe handling and transportation of these alloys. Compliance with GB/T 4008-2024 is essential for manufacturers, suppliers, and users to maintain product quality and meet industry requirements.
