Guys, may I ask about the material of the cylinders in high-pressure air compressors?
Thread Content
We are currently using an experimental high-pressure air compressor with a pressure of 30 MPA. For testing, QT500 cast iron has been used (it’s not clear whether it’s genuine or not). Is there any better material available? Also, what about the materials for the exhaust valve, valve seat, and valve disc – something that is more wear-resistant?
Temperature is also a key parameter; it is through pressure and temperature that the material selection can be determined
