Alloy 4340 plate is another general purpose grade of steel used for industrial and machining applications. For highly stressed parts it is excellent choice. Alloy steel 4340 steel plate standard mill sizes for alloy steel 4340 steel plate range from 19 all the way up to 6.
Other sizes may be available. 4340 alloy steel also known as aisi 4340 is a low alloy steel with high toughness in an annealed state. Aisi 4340 e4340 alloy steel is a medium carbon low alloy steel known for its toughness and strength. 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.
Machining is done typically in the annealed condition. 4340 is a heat treatable low alloy steel containing nickel chromium and molybdenum. When heat treated it is known for its toughness while preserving good fatigue strength. 4340 steel is mainly iron based with nickel being the other major chemical property.
It can be machined by all customary methods. The inclusion of nickel in alloy 4340 helps simplify heat treatment. In addition the nickel in alloy 4340 increases hardenability of the steel. Description alloy steel 4340 is another alloy known for superior mechanical properties.
