AR400 Mechanical Properties

[sloth4z]

I have been asked to run an FEA on a fan using AR400 material for the blades. Can anyone provide the following mechanical properties?

Elastic Modulus
Poisson's Ratio
Shear Modulus
Mass Density
Tensile Strength
Compressive Strength
Yield Strength
Thermal Expansion Coefficient
Thermal Conductivity
Specific Heat

I have done a little research into AR400 and found that it is not intended for structural use. I would appreciate any opinions on that as well. Basically I would like your opinions for or against.

The airstream temperature is 300°F. I have read in another thread that 450°F is the limit because at that point you are removing the heat treating. Would the yield strength, and/or modulus of elasticity (or any property for that matter) drastically change at 300°F?

Typically we would use A588 (or A514) with a chrome carbide liner for abrasive resistance. In this case we were specifically asked to use AR400 only. I just don't have enough information on it to make a good engineering decision, so any information will be greatly appreciated.

You are absolutely correct in your assumption. We had just finished a project to replace four (4) large induced draft boiler fans. The fans were fabricated of ASTM A 588 material. AR400 is an abrasion resisitant plate material that is not intended to be used for fabricating rotating equipment. It can be used as liner material for blades, but not for fan rotor base metal construction.
