That surprises me. Stainless is much harder than brass, and the shearing force for a like-sized SS pin vs brass must be *much* higher (an assumption on my part; never had a metallurgical course.)
A quick look on the web, while it didn't yield a ton of hits, all had brass shear pins as the primary product, with "Stainless available" as an aside.
