Larson Miller parameters 347H

[Ehiman1]

Good Morning to everyone,
I have to check a pressure vessel in 347H material at creep temeperature.
Does someone have Larson-Miller parameters or table for this material?
I have to use it at 1200F.
I want to show that we can use it at 1200F without problem (creep starts from 1050F).


Many thanks
Regards

Dear extragol1A,

The Larson & Miller parameter was formulated in 1952. The 347H was developed later.
