Historical Steel Grade V50 1

[VirtualWorker]

I have a set of structural drawings from 1974 in which V50 is used to specify steel type for a handful of girders. An example of the usage is “W24X55 V50”. It seems logical to infer that 50ksi steel is being called out. Is anyone familiar with the terminology? I have the AISC Steel Design Guide 15, which covers this sort of thing, but I can’t seem to find any reference to V50.

See page E-27 of this NIST document (.pdf) about the steel used in the World Trade Center. The V50 steel properties are listed in a table on that page. It was a product of Bethlehem Steel. Here is the link:

Thank you, that is what I was looking for.
