It has high strength, toughness and excellent quenching and anti-overheating stability, but the white point is highly sensitive and has a temper brittleness.The welding property is poor, before welding, it needs to be preheated by high temperature. After welding, the stress should be eliminated and applied after adjustment.
Important parts for high production strength, good plasticity, and special functional requirements after nitride disposal, such as shaft, gear, fasteners, etc.
Used as require good toughness, high strength, as well as the important conditioning of large size, heavy machinery such as high load of axial, turbine shaft, larger than 250 mm in diameter of helicopter rotor shaft, turbojet engine turbine shaft, blade, high load of transmission parts, fasteners of the crankshaft.Gear, etc.
It can also be used for operating temperature over 400 ℃ of rotor shaft and blade, etc.
It can also be used to make important parts for special performance after nitride treatment, and can be used in high strength steel after low temperature tempering or after isothermal quenching.
Delivery in heat treatment (positive fire, annealing or high temperature tempering) or not heat treatment.
For abundant stock, 15-20 days.For customized products, 30-50 days.
