Need out of the box solutions for steel

[tkittel]

It would be great with some reasonable data files and recipes for a few different steels, since this material is not that uncommon in instrumentation support. It is unfortunately also a rather complex subject (hence the need for some easy to use premade materials supplied by NCrystal).

One typical source of compositions for radiation transport is report PNNL-15870. In includes many standard compositions, and other compositions that are not standard but could be used as a start point for the analysis.

Edit: it is already available from Pyne.
