Specific Heat Of Some Steel Material

That's a cosmopolitan grab bag of standards. (European Norm, British Standard, Japan Industrial Standard,...)

Carbon steel specific heats are around 0.11-0.12 (based on water = 1.00)
Stainless steels are a bit more, about 0.12-0.13.
Strontium ferrite, I don't know, but many metals are around 0.10-0.20.

Some of this can be searched on Google, and MatWeb is also a likely source.
