Creep Constants for Combined Time Hardening

I am looking for a set of creep constants (C1-C7) for "Combined Time Hardening" (TBOPT=11) of low alloyed steel to get started with creep simulations. 

Unfortunately, I don't have any experimental data available. The temperature range of interest is 750-1000 °C. Any data set within this range is welcome.

Can anyone recommend a good source for those constants?

Note sure if the following are useful: 

  • NIST publication from 1928:
  • Creep Data from Plymouth University:

Hi Paul,

The Plymouth line doesn't work anymore.
