The use of high-chromium ferritic stainless steel has been severely limited by such problems as 475 C embrittlement, σ -phase embrittlement, notch sensitivity, and high-temperature (>1000C) embrittlement. Recent surveys by Thielsch1  and the ASTM2  summarize the literature on these problems. This presentation is directed to the last of these - high-temperature embrittlement - which has restricted the use of the relatively inexpensive ferritic alloys as engineering materials.
