Abstract:Disposable Forged Rotary Support Seat is one of the task projects in the third batch of 2022 Social organization Standards revision plan issued by the Shanxi Public Brand Construction Federation. A crucial aspect of drafting social organization standards for manufacturing products is the analysis of the testing or validation of the products involved in the project. Through the analysis of key indicators of raw materials and process control such as chemical composition testing, mechanical performance analysis, and metallographic experiments, the key indicator requirements of the social organization standards have been determined. The significance of drafting standards lies in cultivating the team responsible for drafting standards and laying a solid foundation for the high-quality innovation and development of enterprises.表1 Q355B钢材化学成分要求
