4340 Alloy Steel Material Datasheet 4340 Alloy Steel Material Datasheet4340 Alloy Steel Material Datasheet AISI 4340 - HowcoAISI 4340 is a low alloy steel containing nominally 0.4% C, 0.8% Cr, 0.25% Mo and 1.8% Ni. Higher strength levels up to 150 KSI 0.2% PS may be achieved by suitable heat treatment. Often used in preference to AISI 4140 at the higher strength levels because of its better hardenability and improved CVN impact toughness.
