Why do some material parameters have thickness requirements?
Thread Content
Sometimes when checking information, you will encounter such a situation. The material parameters of the steel plate should be a certain fixed value. Why is there sometimes the thickness of the steel plate in front? Can this data be used for steel plates of other thicknesses?
For example, check the fracture toughness of 15MnVR. This is a material parameter and a fixed value, but a steel plate thickness value is appended to the front of the parameter table. Some say it’s because this value was measured at this thickness. I don’t know if that’s correct.
The thickness of the pressure vessel corresponds to the parameters and cannot be interchanged.
It refers specifically to materials, not pressure vessels: loveliness:
Since the rolling level of steel mills is limited, when the plate thickness increases, some performance indicators will decrease, so the thickness is specified. Asme materials only specify performance based on ingredients. Explain a problem we * * The smelting level still needs to be improved.
