Rebar Billets 2

[BigH]

A quick one - from a technical point of view, it is really necessary that steel billets for rebar be from virgin steel or can re-rolled steel billets (scrap) be used too? What is pros and cons? Is it okay so long as all steel properties are met? What is your practice? Thanks . . .

BigH - In the US reinforcing steel is usually made in electric arc furnaces with scrap steel as the primary raw material.

It's not like they take a bunch of scrap and just roll it into another chunk of steel. The stuff is melted, once you get to that point, it doesn't matter where it came from.
