[MW:35020] Re: Use of Low alloy steels at high temps

this is not fully answer to your very elaborative question, but in short,

1. Low-alloy steels contain alloy element Cr, Mo, V, Ni

2. Low-alloy steels has a balanced compositions of above alloy element to resist  475C embrittlement, HTHA, Graphitization.

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.
