A615 vs A996

A615 vs A996

A615 vs A996

(OP)
I'm working on a project where the contractor would like to use ASTM A996 rebar in lieu of A615. I'm not familiar at all with A996. Are there any pluses/minuses between the two? Can A996 grade 60 be substituted straight for A615 grade 60? Why isn't A996 in greater use? Is there any real reason to reject A996?

thanks.

RE: A615 vs A996

A996 is allowed under ACI 318 so long as it's type R. Would make sure the grade is right as well.

RE: A615 vs A996

ASTM A996 axle steel is available in grade 60 and is a direct substitute for ASTM A615 grade 60. The one US producer of axle steel rebar make a product to A615 standards, but since A615 in "new billet steel" the axle steel cannot be spec'd as A615.

As I said, there is only one producer of A996 that we know of, and they consume most of the north American railroad axles. Rail axles are a tightly graded steel so quality is well controlled. There is no reason to exclude A996 axe steel from your projects.

I do not think anyone is making rail steel in the US, and it is not an acceptable substitute for most uses.

Thanks John, That's exactly the type of information I was looking for.

I was especially wondering why it wasn't just graded A615, but that answer makes sense.
