Dear teachers, while reviewing GB/T713.7-2023 today, I noticed that impact data has been added for austenitic stainless steels; the value in the -196 column is understood to be in line with industry practices. Although it is stated that impact testing is not mandatory per the standard, when is it required for austenitic stainless steel at 20°C? Is there such a working condition? Moreover, at 20°C values are provided for both the longitudinal and transverse directions
The addition of impact data at 20°C is intended to provide a more comprehensive assessment of the toughness of austenitic stainless steels at different temperatures. Although austenitic stainless steels generally exhibit good toughness at room temperature, it is still important to understand their impact properties at normal temperatures in certain applications, such as those involving dynamic loads or impacts. By providing longitudinal and transverse data, it is possible to gain a more comprehensive understanding of the impact performance of the material in different directions, which is very valuable information for designing and using structural components made from this material. .
Stainless steel containers prior to the 196 version of GB150 are also considered low-temperature containers

There are many scenarios in which stainless steel is used at room temperature, especially for transporting toxic and harmful substances.
Over-medical treatment involves taking more X-rays and CT scans, which helps doctors gain a better understanding of you and is beneficial for analyzing your condition.
