Anyone know the properties of SNC 415 H steel? Specifically, I am looking for: 1. Young's modulus (modulus of elasticity) 2. Poisson's ratio Or at least can you point me in the right direction to finding it? Thanks

Are you looking for these properties in order to calculate strength? If so, be aware that once hardened, strength changes. So, knowing E may not give you what you need. As for properties, you may end up having to contact a manufacturer for that. You can try Matweb but I didn't see anything obvious there when I looked.
