Metal plate processing
Metal plate processing
(OP)
A hot rolled carbon steel stack (nothing special)was specified. It operates at about 200F, 2' diameter and about 30' tall. The fabricator built it out of cold rolled material. The project wanted to know if this was acceptable. I use ASME Section VIII all the time but this question doesn't come up. I don't see any problem at all. There is a ladder (probably A-36)that will be welded to the stack. However, the question just keeps getting asked...so I'm asking it here. Does anyone have an opinion?

I don't believe any fabricator would use cold rolled plate in place of hot rolled unless it was less than .25 thickness. The price penalty would be substantial.
