alloying elements that effect low temp charpy strength
alloying elements that effect low temp charpy strength
(OP)
I was wondering if there is a table or publication which addresses the effects of the alloying elements and their direct effect on low temperature charpy readings. I am trying to compile a list of predictors so i can better select raw materials prior to the testing.

You mentioned alloying elements, but S & P, often considered impurities rather than alloying elements, often have a negative effect. However, Mn at the correct level can largely negate small amounts (0.05 wt%) of S.
Some good introductory reading on steel -- alloying, embrittlement, fracture, heat treatment, mechanical testing, microstructure, etc., here:

Of course, you could simply use wrought aluminum or austenitic stainlesses for low temperatures. Their crystal structures have more slip systems available for plastic deformation than the usual steels.

Also try "Ferroalloys and alloying additives handbook" Shieldalloy Metallurgical Corporation. This goes through all of the common alloys.
