What is the typical allowable stress for 20# steel?
Thread Content
What is the typical allowable stress for ordinary carbon steel, such as 20# steel? Is it similar to Q235A, Q235B, 304, 304L, and 316?
I don’t understand; I’ll keep an eye on it. Waiting for an answer
Steel grade, steel pipe standard, wall thickness, allowable stress at the following temperatures: ≤20: 100, 150, 200, 250, 300, 350, 400, 425, 450, 475; 20: GB8163: ≤10: 130, 130, 130, 123, 110, 101, 92, 86, 83, 61, 41; GB9948: ≤16: 137, 137, 132, 123, 110, 101, 92, 86, 83, 61, 41; GB6479: ≤16: 137, 137, 132, 123, 110, 101, 92, 86, 83, 61, 41; 17–40: 137, 132, 126, 116, 104, 95, 86, 79, 73, 61, 41
The answer above is correct; hehe, the person above did a great job
Find a copy of GB150 and take a look; all these data are listed there
It’s related to temperature, haha; check the data sheet
