... fissuring was instigated as a result of the failure. It was concluded after laboratory radiography and macroexamination that if the fissure were large enough to show on a radiograph, either with or without the catalyst, the tube could be expected to fail within one year. The set up for in-service radiograph...

.... Chemical analysis of one of the pitted tubes yielded the following results: 17.35 wt.% Cr, 13.46 wt.% Ni, and 2.19 wt.% Mo. These values fall within the specification for type 316 stainless steel. Macroexamination of the tested tube indicated that it was seamless. Microexamination of the tubes showed...
