Hello Yan,

I am pleased to hear that someone is learning to perform wet chemical 
analysis on steels.  It is a skill that is rapidly becoming a lost art.  
Arc and spark emission, inductively coupled plasma, X-Ray and atomic 
absorption spectroscopy are all commonly used analytical methods in the 
steel industry.  It has become common practice to use one instrumental 
technique to calibrate another.

Very often, getting the entire sample to disolve into solution is the 
hardest part of the analysis.  For gravimetric analysis, the element of 
interest must be separated, or else the menthod is not specific and other 
elements will interfere.

The best source for the information you require is the American Society for 
Testing and Materials (ASTM).  ASTM methods E350 through E354 describe the 
accepted methods for wet chemical analysis of various types of steels.  You 
will probably need copies of all of the methods, as they often refer to 
each other for specific elemental analysis methods.

The ASTM methods are published yearly in the Annual Book of ASTM Standards, 
which should be available at most university libraries.
