Steel Material Properties
(OP)
I'm working on an analysis of an existing structure (1990 construction) where the original steel was called out as "V-star 50 Group A Steel." This sounds like a trade name. Does anyone know the original manufacturer or what the ASTM associated with this steel would be?
Thanks!
Thanks!

I couldn't find V-Star referenced to a steel product in the trademark registration. There's not that many V-companies, though. Could it be a Vulcraft product, for example?

Bethlehem did have a steel grade called "V-STAR 50".
When Bethlehem introduced their high-strength structural steels in the 60's they called them "V-Steels" since their strength came from Vanadium. USS (EX-TEN) used Columbium. These steels became ASTM A572.
In 1991 Bethlehem's H and sheet piling sections (and structural shapes) became available as "V-STAR 50" = (Vanadium - Strength, Toughness, As Rolled w/ a 50 ksi yield). It conformed to A572-Grade 50.
We offered PZ35/40 to CVN 15 Ft-Lb @ 0 degrees F and all other sheet piling and H-piling sections to CVN 15 Ft-Lb @ -50 degrees F.
V-Star 50 also had improved weldability.
I don't know what the "...... Group A Steel" is all about.
