Just did a quick matweb search and found that the following types of stainless steel all have ranges of yield strength beyond the 73000 psi listed for 7075 Aluminum:

302, 305, 308, 309, 310, 329, 347, 348, 403, 405, 410, 414, 416, 420, 422, 446, 450, 455, 630, 651, 660 & 675

Some of these appear to be dependent on the heat treatment while others are not. I have no feel for which of these types of stainless steel AM may be using or which kinds are even common, so it is tough to have a good basis of comparison for the different materials used in the dogs.
