Answer
I have found in my research that 4140/4142 is the closest US comparable grade of material to 42CrMo4.
Use the link to a site where you can find more information on other comparable grades of alloys form US to International call outs.
Answer
708M40 or EN19a
A material with definite properties and definite chemical composition is called a pure substance.
Taste is derived from the chemical composition and chemical properties of a material.
CRS is the acronym for Corrsion Resistant Steel; for the chemical composition of a typical material see the link below.
You must be familiar with working material composition; you can not do with insufficient material knowledge a chemical industry.
That process is called transformation or transmutation where the original material undergoes a change in its chemical or physical composition resulting in a new material.

No to both.

Minerals have a definite chemical composition, are solid, are inorganic, are naturally occurring, and have a crystalline structure.
Breaking glass is a physical change, as it does not change the chemical composition of the material.
The chemical composition of the steel 1.0120 is:- manganese: 1,6 %- silicon: 0,5 %- chromium: 0,3 %- nickel: 0,3 %- carbon: 0,12-0,17 %
Chemical weathering changes the composition of materials through processes like oxidation, hydrolysis, and dissolution. These processes break down minerals into new substances, altering the chemical composition of the rock.
Any material has a chemical composition; potatoes can be tested for residues of pesticides.
No, thermal expansion is a physical change, not a chemical change. It occurs when a material expands or contracts in response to changes in temperature, without any change in the chemical composition of the material.
