4340 Alloy Steel Data Sheet

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 alloy steel data sheet. 4340 steel is mainly iron based with nickel being the other major chemical property. High strength alloy steel. Data sheet general characteristics. La aleación 4340 alloy steel de neonickel es un acero de baja aleación que se puede tratar térmicamente y contiene cromo níquel y molibdeno.

Alloy 4340 in plate specifications. 4340 var ams 6414 is a low alloy chromium nickel molybdenum steel capable of being heat treated to high strength levels. The high fatigue strength makes e4340 ideal for highly stress parts as it maintains it s strength and hardness at elevated temperatures. Due to e 4340 s high alloy content it obtains a uniformed hardness by heat treatment.
