4.Features:
Excellent hardenability, high toughness and good heat-resistance
and fatigue-resistance.
5.Heat treatment:
Quenching 850 degrees; coolant: oil;
tempering temperature of 600 degrees; coolant: water, oil;
Steel annealing or high temperature tempering supply state Brinell
hardness GBW is less than or equal to 269.
6.Application:
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 ºC of rotor
shaft and blade, etc. and after nitriding processing can also be
used to make special performance requirements of the important
parts, after low temperature tempering or can be used for
ultra-high strength steel after thermal quenching.
