ASTM-A285-49T
(OP)
I have a project involving modifications to a plate steel penstock serving a hydro power plant build in the early 1950's. The plate steel is noted to conform with "ASTM-A285-49T" spec's. While I have material data for more recent "ASTM-A285" standards I am unable to locate anything on the "49T" standard. Can anyone provide material spec's in accordance with this old standard?
Thanks for any help you may provide

There are three Grades, A,B, and C. Regarding chemistry and tensile requirements there are flange and firebox quality for all three Grades.
T by the way is for tentative standard.
