Parts running in a vacuum furnace at 1950F. Parts are not compacted. Hanging close but no compression on any parts.. The parts are coming in exactly to spec as we put them through a gage prior to running. We are getting various % of fallout on each trial run. We drop them in a gage to show any distortion. Looks to be getting expansion distortion.

Looking for some advice. What is the best way to reduce distortion with 420 material? Running parts hanging vertically from a fixture at 1950 with a 2bar quench 50% fan speed. I have the ability to hang the parts horizontally. Will this help with any distortion since the weight will be dispersed over a larger surface VS all the weight on a vertical end it is hanged from? thank you
