There is currently such a working condition: design pressure: 4.6 MPa (a)； Design temperature: 280 degrees ； Medium: Saturated steam. I saw that 15CrMo is specified in the materials list, and I would like to ask if it’s okay to use 20# steel instead? Thank you!

There should be no problems with 20#, as it can withstand both pressure and temperature; there is no need to necessarily use 15CrMo

I have a gentle question: Is 20-grade steel a forged steel? It seems that many seamless steel pipes are made from this material

Forged steel? They’re not talking about the same thing.
