The numbers 4130 defines the chemical composition of the steel.


1. 41 means a low alloy steel containing 1 % chromium and 0.2 % molybdenum.
2. 30 means a carbon content of 0.30%.
3. 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.
4. The remaining 97-98 % is iron.

AISI 4130 is a Standard grade Alloy Steel.
It is commonly called AISI 4130 Chromium-molybdenum steel.
It is composed of (in weight percentage) 0.28-0.33% Carbon (C),
0.40-0.60% Manganese (Mn),
0.035%(max) Phosphorus (P),
0.04%(max) Sulfur (S),
0.15-0.30% Silicon (Si),
0.80-1.10% Chromium (Cr),
0.15-0.25% Molybdenum (Mo),
and the base metal Iron (Fe).
Other designations of AISI 4130 alloy steel include UNS G41300 and AISI 4130.
