20, Selection between Q235B and Q235A

This post was last edited by Yourongnai Da on 2011-11-25 at 15:07. Regarding material selection, GB150 specifies the materials to be used for the shell, with Q235B and Q235C being the common choices in terms of thickness; what about 20R and Q235A (for normal pressure conditions)? Is the flange material the same as that of the housing?

First, Q235-A is not available. For the other 150 grades, no maximum thickness is specified; I believe any thickness specified in the allowable stress tables for those grades can be used.
