Re:Young's Modulus for Acquamet 17
(OP)
Hi, folks,
Does anyone know Acquamet 17 stainless steel? It is used for propeller shafts in marine industry. Me and lots of people involved in project are having hard times searching for the manufacturer. We need to calculate torque on the shaft, hence we need Modulus of Rigidity or Elasticity.
Thanks for any help.

The stainless expert at Crucible is William Nesspor, and I recommend that you speak with him directly.
The modulus of elasticity E for the vast majority of iron based alloys falls within the range of 28,000 ksi to 32,000 ksi. The stainless grades tend to favor the lower side of this range, and the moduli are relatively insensitive to heat treatment. The shear modulus G can be calculated for an isotropic elastic solid from the relationship
G = 2E/(1 + v)
where E is the elastic modulus and v is Poisson's ratio.

G = E/[2(1 + v)]
The Poisson ratio provided by Unclesyd should be 0.291, not 0.0291. If these errors are corrected, the calculated value of G is 11,270,000 ksi, in agreement with the value quoted by Unclesyd.

Thanks,
The problem was me blind copying numbers without thinking. I have sent an E-mail to Western Branch Metals pointing out the error in the brochure.
