Hot Rolled 4340 Alloy Steel Round Bar For Machine Shafts

Aisi4340 40CrNiMo round bar, 40CrNiMo alloy structural steel is also a kind of gear steel

Application:

To manufacture important parts with high strength and good plasticity, and to manufacture important parts with special functional requirements after nitriding treatment, such as shafts, gears, fasteners, etc.

Specification:

It has high strength, toughness, excellent hardenability and stability against overheating, but high sensitivity to white spots and temper brittleness. It has poor weldability. It needs to be preheated at high temperature before welding, and it needs to be stress relieved after welding and used after quenching and tempering.

1. Mechanical properties:

Elongation δ 5 (%): ≥ 12

Reduction of area ψ (%): ≥ 55

Impact energy Akv (J): ≥ 78

Impact toughness value α kV (J / cm2): ≥ 98 (10)

Sample size: sample blank size is 25 mm
