GB/T 44155-2024 in English

The standard GB/T 44155-2024, titled "Steel Forgings - Frequency of Mechanical Property Testing, Sampling Conditions, and Test Methods," was issued by the National Standardization Management Committee of China on June 29, 2024, and will come into effect on January 1, 2025. This standard provides comprehensive guidelines for determining the frequency of mechanical property testing, the conditions for sampling, and the methods for conducting tests on steel forgings. It is designed to ensure the quality and reliability of steel forgings used in various industrial applications by establishing uniform testing procedures.

The standard specifies the requirements for the selection of test samples, including the location and orientation of the samples, to ensure that the test results are representative of the entire forging. It also outlines the procedures for conducting tensile tests, impact tests, and hardness tests, which are essential for assessing the mechanical properties of steel forgings. The frequency of testing is determined based on the type of forging, its intended application, and the criticality of the component in service.

GB/T 44155-2024 aims to provide a standardized approach to mechanical property testing, ensuring consistency and comparability of test results across different laboratories and manufacturing facilities. By adhering to this standard, manufacturers can enhance the quality control of their steel forgings, thereby improving the safety and performance of the final products in industries such as automotive, aerospace, and heavy machinery.
