... At higher solution temperatures, sensitized type 304 and type 316 are particularly susceptible to SCC, whether caused by chlorides, sulfur compounds, or caustic. For example, type 304 or 316 kraft black liquor evaporators and white liquor tubing are subject to SCC in sensitized HAZs. In many cases cracking...
