Chemical Cleaning of 304 and 304-L Stainless Steel Surfaces by the Nitradd Passivation Process

摘要

A chemical cleaning process was established at Mound to prepare 304 and 304-L stainlless steel surfaces for welding operations. This process was adapted from an existing production procedure used at the Rocky Flats Plant. The results of the two processes were compared by means of Auger Electron Spectroscopy (AES). The AES data showed that the Rocky Flats process and the process established at Mound produce comparable results. Consequently, the Mound process is a viable one and is being used to prepare specimens for welding experiments. (ERA citation 10:007100)
