About AISI 4340 Density
AISI 4340 is a grade of steel that has high strength and very good toughness. It can be hardened to Rockwell C 60, which means it can resist fatigue and stress corrosion cracking (SCC). It also has excellent formability, weldability, machinability, and is comparatively lower in price than other alloys with the same properties. AISI 4340 offers up to 5% better performance in tensile yield point and ultimate tensile strength than AISI 4130. The density of this alloy is 0.283 lb/in3.
