Description
Description:
Most of the steam turbine fasteners work at high temperature and high pressure for a long time, requires very high quality material and material processing. Generally, high strength and high temperature resistant materials such as alloy steel, heat- resistant stainless steel and superalloy are adopted, and heat treatment, blackening and non-destructive detection are applied.
Regular used material includes:
21CrMoV5-7
20Cr1Mo1VTIB/VNbTiB
2Cr11NiMoNbVN
20Cr1Mo1VNbTiB
2Cr12NiMoWV
1Cr11Co3W3NiMoVNbNB)
1Cr11MoNiW1VNbN
R26
GH4169
Ni80TiAl
In order to adapt to the working environment of high temperature, high stress, and steam oxidation corrosion, the steel used for making steam turbine fasteners needs to have good strength, toughness, oxidation resistance, creep resistance, and relaxation performance, low heat embrittlement tendency, low notch sensitivity, and a certain degree of corrosion resistance.
