475 may not happen in low alloy steel.
Sigma phase formation will happen when --if %Cr-16%C/%Ni, Less than 1.7, No sigma phase, if it is more than 1.7 , Sigma phase

Hi fellows,--I wanted to know why low alloys are used in high temperature service and how they resist damage mechanisms like 475C embrittlement, HTHA, Graphitization. I guidance regarding reasons behind their selection other than cost savings.Thanks.
