So you have to calculate the heat transfer and estimate the surface temperatures in all heaters and coolers to find if you have the risk for temperatures so high that SCC might occur. I am interested in the crygenic treatment of metals as an alternative to heat treatment. Please email me since I am rarely able to check this newsgroup. Thank you in advance. Weldability and fear of permanent deformation or as-welded fatigue might drive the use of one over another.
Same comments apply to various steel alloys.
Probably there are other books with more extensive elastic data. M25-1, specifically yield strength vs. temperature. Any reference recommendations would be appreciated. Generally 400 C will give a full anneal with minimum grain growth. Inc. I'm sure they would gladly provide the data you want.
