About 4340 Alloy Steel. 4340 Alloy Steel is an iron based alloy containing nickel, chromium and molybdenum. The relatively high carbon content provides this alloy with superior strength in applications where severe service conditions exist. 4340 Alloy Steel 4340 High Tensile Steel Interlloy Engineering Steels AISI 4340. ASTM A29/A29M 1991 4340. ASTM A322 4340. ASTM A331 4340 Cold Finished. SAE 4340. N.B. Nickel is inert to the action of nitrogen and in general resists its diffusion into steel. This can result in lower case hardness or longer nitriding cycle times for steels containing nickel such as 4340.

4340 alloy steel (also known as AISI 4340) is a low alloy steel with high toughness in an annealed state. 4340 alloy steel is characterized by its outstanding ductility, formability, and weldability rendering it an excellent metal for a variety of structural applications and components including power transmission gears and shafts, aircraft parts, and machinery. 4340 steel is mainly iron based AISI/SAE Steel and Alloy Designation SystemThe system is based on the chemical compositions of the steels and alloys. Example AISI/SAE No. 1020. the first digit indicates that this is plain carbon steel. the second digit indicates there are no alloying elements; the last two digits indicates that the steel contains approximately 0.20 percent carbon ; Example AISI/SAE No. 4340AISI 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.
