AISI/SAE 4340 Alloy Steel- 4340 Steel Properties | All
AISI/SAE 4340 Alloy Steel, 4340, is a nickel-chromium-molybdenum alloy steel known for its toughness and its ability to attain high strengths in the heat-treated condition. Commercial and military aircraft, automotive systems, forged hydraulic and other machine tool applications, forged steel crankshafts.
AISI 4340 steel is a medium carbon, low alloy steel known for its toughness and strength in relatively large sections. AISI 4340 is also one kind of nickel chromium molybdenum steels. 4340 alloy steel is generally supplied hardened and tempered in the tensile range of 930 – 1080 Mpa.
Alloy 4340 plate is another general purpose grade of steel used for industrial and machining applications. The inclusion of Nickel in Alloy 4340 helps simplify heat treatment. In addition, the Nickel in Alloy 4340 increases hardenability of the steel. An additional grade of Alloy 4340 is Alloy E-4340.
