Rebar made from Rail Steel
Rebar made from Rail Steel
(OP)
My understanding is that rail steel is not produced in any specific yield strength, but rebar has been made from re-rolled rail steel for many decades. One manufacturer's data says that it is 50,000 psi yield strength. I am checking a structure built in 1957 (which may or may not have used rail steel rebar) but using current code to check, so I need to know the yield strength. Does anyone know where I could find out if rail steel was ever produced in yield strength less than 50,000 psi?






RE: Rebar made from Rail Steel
Was rebar ever made from "re-rolled rail steel" or was that just a matter of nomenclature? I ask because, for example, one of the common grades of steel cable/ wire rope is made from "Improved plow steel". That's specifying a grade or type of steel, but doesn't imply that the material was ever part of a plow, either, and it may be a similar case with the rebar. In modern practice, scrap is all melted down and they'll adjust the chemistry as required in the process, so it doesn't much matter what you started with.

Rail steel also typically has a yield strength of about double of what you mentioned. Nowadays, that is. Can't say what was used in 1950's.
