The numbers 4130 defines the chemical composition of the steel.
|•||41 means a low alloy steel containing 1 % chromium and 0.2 % molybdenum.|
|•||30 means a carbon content of 0.30%.|
|•||In addition there will be around 0.2-0.5 % silicon, 0.5-1.0 % manganese, and under 0.1 %|
|of each of a dozen or so other elements whose presence is unavoidable.|
|•||The remaining 97-98 % is iron.|
