    16Mo5+1.4002 cladding

    Hello. Thank you very much for your opinions. The cracks were on the inside, on the cladding side. Finally, they remove the cracks, but they didn't want to weld. I think they will monitor the evolution of the vessel during operation.

    304H+Grade P11

    Good afternoon. I have a situation where I have to weld a 304H pipe to a P11 pipe. (D=1800mm) I was thinking at 2 options: 1. Welding directly with ENiCrFe-3 (no PWHT, no preheat) 2. Deposit on P11 pipe an EniCrFe-3 layer (above 6mm), after that make the PWHT of the bevel and then weld the P11...

    Stabilize annealing 347H Stainless steel

    In this case you have to do it. (it's the client request). Make sure if the hardness is HV5 or HV10. Once i had a dispute about it, so maybe it will be helpful for you. I suppose you can try also with a TQ, if you don't wanna do it.

    Stabilize annealing 347H Stainless steel

    Hello. I saw that in ASME B31.3-2014 edition they took out the table with the requirements for the hardness test, so you don't have any reference. (maybe in the client specifications you can find something). Do you have any supplementary requirements, such as NACE?

    P355NL1 - grouping

    The analyze of the mechanical properties showed a value of the yield strength = 372 MPa (this is for a pipe with dimensions 60.3x8.74) It could be a mistake from the producer.

    Preheating A335 P5

    Thank you for your answer, metengr. I was asking because I saw that many companies are doing the preheat with the electrical resistance, and I was wondering if using propane it's a problem due hydrogen content. I think that if you are using only GTAW, with low hydrogen filler metal and you...
