Is this 400 Stainless Steel? Bolt Busters

Nothing quite as productive as testing hangers that no longer exist! Rumor has it that climbtech made a 400 series stainless steel hanger instead of 304 or 316 like many stainless hangers are made of. They are magnetic and supposedly break without stretching as much as a other stainless. They discountinued it but it was a discussion found on Mountain Project at https://www.mountainproject.com/forum/topic/117134281/id-these-mystery-hangers#ForumMessage-117134310. These were donated by Greg Barnes from the ASCA https://safeclimbing.org/

We found the 22kn mbs hangers to be just as strong as the 25kn hangers. And they both broke like taffy.
➜➜➜400ss with 22kn MBS hangers broke at 36+, 36.48kn and 36.38kn
➜➜➜304ss with 25kn MBS hangers broke at 34.68kn, 37.10kn and 37.82kn
