Regarding the maximum operating temperatures for various materials
Thread Content
Dear seniors, how can we determine the maximum operating temperature for a certain steel material? Can it be determined using the various parameters shown in the diagram?
The maximum operating temperature should be determined based on the application of the material and the temperatures specified in relevant standards. For example, when using Q235B for pressure vessels, according to GB150, the maximum operating temperature is 300 degrees. If used for other structural steels, it can exceed 300 degrees.
No, check the last level of allowable stress
The maximum operating temperature should be determined based on the application of the material and the temperatures specified in relevant standards. For example, when using Q235B for pressure vessels, according to GB150, the maximum operating temperature is 300 degrees. If used for other structural steels, it can exceed 300 degrees.
For containers designed in accordance with GB/T150, the temperature range of use for steel containers is determined based on the allowable temperature range for the materials specified in GB/T150.2. There are specific temperature limits for the use of materials in plates, tubes, forgings, and fasteners. It cannot be determined from the table provided by the original poster. If designed according to other standards, the range of limitations will be different.
