“When the wall thickness is determined by negative pressure, Q235B should be given priority. ”What is the reason behind the phrase “Newbie Growth Notes”?
First, set aside the standard restrictions on the use of Q235B. I’ve never heard the statement made by the original poster, but under negative pressure conditions, it is the elastic modulus that determines the wall thickness. Since both are carbon steel materials with similar elastic moduli, Q235B is relatively much cheaper.
