Does anyone know of any good P22 creep data that I might be able to get a hold of? Specifically I am looking for the effects of creep if you increase the operating temperature from 900F to 950F for P22. I found some data on creep for P22 tubing in terms of time to rupture (hr) vs. test...
Can anyone give me some more detailed information on the phenomenon of carbon contamination of P91 material when it comes into contact with carbon steel (e.g. when carbon steel is used to lift P91 material, some of the carbon steel material gets embedded into the P91 material). Specifically...
Can anyone recommend a good reference for standard micrographs? ASM Handbook Volume 9: Metallography and Microstructures is one reference that I found, but I don't know if there are any others. The reason I am asking is because I am interested in obtaining some reference micrographs of low...
Can anyone point me to some good sources of information on any research that either has been done or is being done on the P5B piping materials (e.g. P91, P92, P122, etc.)? Some specific areas of interest are performing post weld heat treatment at various temperatures, and if a lower limit has...
I have read quite a few threads concerning P91 material, and a few on P92 material, but the information is a little dated (circa 2004/2005). There have been some updates to the ASME codes (allowable stresses, PWHT temperatures, etc.). Can anyone tell me if there has been any other developments...
