China Steam Turbine Fasteners Bolts Nuts Screws Manufacturer

 

 

PRODUCT 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.
