production of API 5L grades
(OP)
Can anybody give me any information about
the production parameters (concerning soaking temperature,
heat treatment, rolling conditions,etc.) and chemical compositions, respectively, to the following
API 5L grades: X60-X80 ?
Thanks for some information!
Best regards,
WoKu

C 0.26 max
Mn 1.4 max
P 0.030 max
S 0.030 max
Nb,V,Ti % or combinations thereof may be furnished by agreement between purchaser and manufacturer.
Note: The C % and the Mn percentage varies slightly for the welded varieties for the various grades but otherwise similar to the above.
API 5L X60, X65, X70, X80 PSL 2-seamless
C 0.24 max
Mn 1.4 max
P 0.025 max
S 0.015 max
Nb,V,Ti % or combinations thereof may be furnished by agreement between purchaser and manufacturer.

These pipes are normally in the Q&Ted conditions. If you need info on the chemical compositions for the welded pipes let me know.
Thanks and regards

RE: production of API 5L grades
Now I do have another question, concerning API 5L grades:
Is there any difference in produce sour and non-sour API 5L steel grades, especially concerning the hot rolling area?

Hi everyone,
I'd like to know about X60-80 microstructure in post fabrication condition and fabrication schedule for welded pipes. I'm working with ultra low carbon steel pipes
RE: production of API 5L grades
For a sour fluid, you need to have tighter requirements than is specificed in API 5L. For example, control the chemistry and toughness of the pipe. Suggest you get help from a metalurgest (never could spell).
