TTT and CCT diagrams of pipeline steels X42 and X70

TTT and CCT diagrams of pipeline steels X42 and X70

(OP)
Hello,

I am looking for Time-temperature transformation (TTT) diagrams and Continuous cooling transformation (CCT) diagrams of the pipeline steels API X42 and X70.

Can anyone tell me where I can find these diagrams, or is there an online resource available ?

Thanks in advance,

Koen

The chemical composition of the X42 we use is :
C%: 0,127; Mn%: 0,641; Si%: 0,183; P%: 0,010; S%: 0,008; Cr%: 0,156; Mo%: 0,035; Ni%:0,129; Cu%: 0,230; Sn%: 0,015; V%: 0,000; Al%: 0,028; Ceq: 0,295

The chemical composition of X70 is :    
C%: 0,11; Si%: 0,36; Mn%: 1,54; P%: 0,012; S%: 0,002; Al%: 0,032; Cu%: 0,05; Cr%: 0,05; Ni%: 0,04; Mo%: 0,01; V%: 0,03; Nb%: 0,03; Ti%: 0,00; N%: 0,008

RE: TTT and CCT diagrams of pipeline steels X42 and X70

Here is an interesting web site by ONL that developed an on-line method for plotting TTT and CCT diagrams using the chemical composition  of the steel;
