CRS is the acronym for Corrsion Resistant Steel; for the chemical composition of a typical material see the link below.
Chemical Reference Standard
For example the steel Fe 500 1586 contain 0,3 % carbon, 0,05 % sulfur, 0,05 % phosphorus.
Strontium Sulfide
The chemical composition remain unchanged.
the chemical composition does not change.
If I under stand your question correctly, you are asking a technical question : What is CRS bar? CRS is Corrosion Resistant Steel reinforcement bars used in Reinforced Cement Concrete. This is not as good as Stainless steel, but better than ordinary Reinforcement bars and is manufactured by some manufacturers like Tata Steel (in India) by giving some surface chemical treatment to the bars. Trust this answers your question.

What is the chemical composition of kf reagent
The chemical composition remain unchanged.
the chemical composition does not change.
Properties of materials depends on the chemical composition.
No. The chemical composition remains the same.
This is the composition of a chemical compound expressed in contained chemical elements.
Phosphorus is one of the chemical elements and therefore has no "chemical composition" in the usual sense.
No. In a physical change, the substance maintains its chemical composition.
