High-temperature bolts

Thread Content

Dear sea friends: Is Incoloy 800H material suitable for use as bolts in high-temperature applications? The gas temperature inside the pipeline is 720 degrees, and bolts are used to connect the flanges.

Materials of 304/304L can be used when the temperature is below 800 degrees and the pressure is below 16 MPa.

Using Incoloy 800H as a bolt fastener is too extravagant; CrMo will suffice

GH162 can be used as the material

310S will do, right?!
