Note: The following list represents the relative cost of common process items in different materials of construction, for use by staff and students in educational institutions for economic calculations. I have taken 304 stainless steel as the basic material and consulted with a number of fabricators and suppliers. It is not intended for any other purpose and does not imply that items will be available from any supplier at that price. The actual cost of a process item will depend upon the method of fabrication and its complexity, quantities ordered, and contract details. Special grades of materials may command a higher price. Having said the above, it is hoped that this table will be of use in giving students a rough but realistic idea of materials costs, and will enable academics to give examples and projects which are at least plausible. I will be pleased to receive suggestions of additions and corrections from knowledgeable parties.
