Annealed 4340 Steel: Crafting Ductility
Annealing, a heat treatment process, transforms the microstructure of 4340 steel by heating it to a specific temperature and then slowly cooling it. Annealed 4340 steel is characterized by improved ductility and machinability. The softer structure resulting from annealing makes it more conducive to processes like machining and forging.
Normalized 4340 Steel: Elevating Strength
Normalization involves heating 4340 steel to a temperature above its transformation range and then air-cooling it. This process refines the grain structure and enhances mechanical properties. Normalized 4340 steel boasts increased hardness, strength, and resistance to wear compared to its annealed counterpart. The improved strength makes it suitable for applications where higher mechanical properties are crucial.
