I'm trying to get a reliable number for Youngs modulus for 13 chrome (410-420 stainless) and super 13 chrome (3-5% nickel added). Ive gotten answers from 29E6 (From JFE) to 32.3E6 (from Kawasaki).
We use this material extensively at 80 ksi yield and 110 ksi yield (and ocasionaly at 125+ yield) at temperatures from 150 to 275 deg. F. The modulus is critical because it affects elastic collapse.
Has anybody got a reference that would give me some kind of justification for a specific number?

Thanks,

Dick

Is there a ASTM, SAE, ASME, or other standard which this material is referred or specified to? Ultimately, what ever industry standard the material is manufactured tois the final word.

13 chrome is an API spec, it includes most 410 and 420 stainless. I have not found a reliable number for 410 stainless. The modulus of elasticity is not a part of any spec that I have found.
13 chrome has the unfortunate property of loosing most of it's impact strength when heat treated to 110 ksi.
Super 13 chrome was developed to cure this problem and is produced by most of the major steel manufactureres (JFE and Kawasaki are two of them). There are slight variations in the amount of nickel and moly between suppliers. It is also called Hyper 13 chrome by some manufacturers. There is no industry standard.
