SAE AISI 4340 Steel Properties, Heat Treatment, Equivalent sae 4340 tensile strength

SAE AISI 4340 Steel (UNS G43400) AISI 4340 steel (UNS G43400) is an ultra-high strength medium carbon low alloy steel, which combines deep hardenability, high ductility, toughness and strength, and has high fatigue resistance and creep resistance. It is not particularly affected by tempering and embrittlement, and exhibits good strength retention at high temperatures and is not easily softened.
