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.
