Understanding the designation
16Mo3 is composition-oriented; its name is not a direct statement of allowable temperature, pressure or service life.
Writing a reliable purchasing specification
Verify 16Mo3 with the precise product standard such as EN 10216-2, dimensional and service requirements, and required test records.
Do similar grades mean the same thing?
16Mo3 must not be automatically exchanged for P235GH or P265GH; their designation systems and material characteristics differ.
