This is not a framing square. It is a Mathey Dearman Pipefitter's square with piping information engraved on it. It is stainless steel and what you would think makes it unique is: it is martensitic stainless steel which means that it is hardened with carbon which means it will attract a magnet. We know because we have we had to go back to the manufacturer after a customer said, "This ain't stainless. My level sticks to it." It turns out that it is not unique because only one type of stainless is non-magnetic and that the Austenitic SS with types that pipe fitters and pipe welders would recognize such as 201, 301, 302, 303, 304, 316. The rest are magnetic. This is the pipefitting square you have been looking for.
