creep range
(OP)
I have a heat exchanger of material SA516-70 , I need to know the creep range of this material and other material , where can I find such a data whether in a code or website ?

However, that is NOT when creep starts. For that, you will need to refer to API 579-1/ASME FFS-1, Table 4.1, titled "Temperature Limit Used To Define The Creep Range". Here, you will find that the creep range actually starts at a lower temperature than would be inferred by the italics method in Section II, Part D. SA-516 Gr. 70, being a carbon steel with a UTS > 60 ksi would start the creep range at 700°F (371°C).

Agree with you on the lower temperature at which creep starts but it is hard to convince people of this.

If it can happen it will happen, somewhere, sometime. Materials are perverse that way.

In addition to the guidance provided by metengr, you may find additional resources at this link http://www.ommi.co.uk/etd/eccc/advancedcreep/DShee....
The steel specifications mentioned in these data sheets conforms to European Specifications. However nearest ASME/ASTM equivalence could always be found by proper searches.
Hope this would help you.
Thanks.
