Information redarding Material

During the NDT inspection of a pump shaft key I rejected the key due to cracking. The material of the key was A276 - 316. Now to machine a new key material 316 is not available
My question is that can we use SS 316L, 304, or 304L instead of SS316 or what is the better alternate.

Thanks & Regards
Muhammad Azhar Jamil Khan

The info you have quoted is for 316 S/Steel bar stock. I would suggest that you need to find out the shear strength for A276-316 and find a comparable material on that basis. I think that you will find that 316 plate is Ok!
