We just had some Maraging C300 parts come back from a standard aging process (6 hrs @ 900F, air cooled) with a 47.5 HRC hardness.
Typically it should be 50-55 HRC. What would be the best course of action to achieve higher through hardness without case hardening or nitriding?
Is there a general guideline for the application of ultra-high strength alloys with low fracture toughness and ductility?
We are comparing the use of Maraging C300 vs C350 in a splined shaft. Maraging's low distortion in HT is a huge plus for us.
C300 looks like the best blend of high yield...
We're looking to maximize the amount of torque we can apply to a short splined shaft (~10,000 reversing cycles). We have been using 4140 previously.
What would be the most important material property to achieve this? We are looking at Aermet 100, Ferrium C61, MP35N... Seems 300M is recommended...
This is a piston I had DMLS printed from AlSi10mg - the geometry is derived from generative design using some basic inputs and a starting shape. It's really just an experiment whether a consumer grade design and print can be bolted in and work for a time.
After machining, it is predicted to...
