I can't answer the question, but maybe you find something usefull in one of my links ? http://www.msm.cam.ac.uk/tribo/tribol.htm http://docenti.ing.unipi.it/tribo/gruppoNEW.html#International http://www.sait.co.za/ http://www-mech.eng.cam.ac.uk/Tribology/ http://www.msm.cam.ac.uk/tribo/links.htm...

I found a pressure vessel steel, P460NL1. It has a yield strength of min. 460 MPa, and is normalised. I looked at this material through the microscope, but it has a banded structure. See : http://www.bil-ibs.be/nl/p460NL1.jpg I fear that the carbon rich zones (with the pearlite) will transform...

That is indeed a possibility. Maybe we have a large-diameter pipe where we can cut plates from. We did that by the way for welding X70. But it's more labour intensive of course... I'll try finding pressure vessel steel ASTM A517. How about the option to use a thermo-mechanical treated steel ...

Stanweld, What do you mean, that we should by pipes, and machine plates out of it ? Metengr, The quenched and tempered materials were used in the beginning, but not anymore. The impact toughness was too low in some cases. Do you think it is possible to buy a plate X52 ? regards, Koen

Do you think a quenched and tempered steel plate is better suitable than a normalised ?

You can see the application here : http://www.bil-ibs.be/eng/Research/research_2004_Friex.htm The plates shall be used for welding trials to join pipes. I would like to use a plate with a high impact toughness (the higher the better). Since the rolling direction of the plate is perpendicular to...

Dear all, I am searching for a fine grained steel plate, which should be normalised or thermo-mechanical treated, and should have a high impact toughness. The steel should have a minimum yield strength of 360 MPa and a tensile strength of 455 MPa, and should have controlled through-thickness...

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...
