Thank you, Yes we are thinking of under-sizing the parts and allow for growth. Since we are in the medical device field, we used the Grade 5 ELI material and also for its better strength properties.
Thank you all for the responses. We have been running some experiments. Heated the tubes at 1450F for 2 hours, air-cooled, measured and the part grows 0.003". Repeated the process and the part further grew 0.002". Finally after 4 heat-treatments the part growth reduced to 0.001". Overall the...
Thank you for the information. Yes, we have tried stress-relieving after machining at 1000F for 2 hours and air-cool. But still the tube grows during nitriding.
I have a question regarding Titanium alloys. We have a tube component made of Ti 6Al-4V, and we nitride the tube at 1450F. After nitriding we are seeing a 0.003”-0.004” expansion in the diameter of the tube, which is not suitable for our application. Can anyone please suggest another Titanium...
