Negative deviation for Q235-B steel plates?
Thread Content
Q235-B is used to manufacture EHB377×8 end caps. According to JB/T 4746-2002 for steel pressure vessel end caps, the actual minimum thickness of the formed end caps must be no less than the nominal thickness of the end cap minus the negative deviation C1 of the steel plate thickness. The actual thicknesses of the two end caps are as follows: End cap 1: 7.5, 7.5, 7.9; End cap 2: 7.3, 7.5, 7.9. I would like to know what the current negative deviation for Q235-B steel plates is
Go and check the standards for Q235-B steel plates
The negative deviation is related to the thickness of the steel plate; for Q235B steel plates with a thickness of 8, the negative deviation is 0.8
