Metallographic structure:

face-centered cubic structure,The extreme low carbon element content ,improve the rate of Ti:C  ,so that it also improve the structural stability, intergranular corrosion resistance.950℃ low temperature annealing assure the crystal structure.

Mechanical properties:

Mechanical properties at room temperature (min)

High temperature mechanical properties (minimum)

Material feature:

High Nickel content in aqueous corrosion conditions it has good resitance to tress corrosion cracking 

High chromium content  it has a better resistance to pitting and crevice corrosion cracking

Has excellent corrosion resistance up to 5℃ extremely high temperature aqueous medium

Good resistance to stress corrosion resitance

Good workability

Application:chemical engineering ,power station,petrochemical engineering ect which is exposed

 to high temperature corrosivity environment.
