ASTM A513 GRADES? TENSILE ?

Date 04-02-2010 16:16

I have Conducted a PQR using ASTM A513 round tube using .035 NR- 211. The tension specimins failed in the base material away from the weld 56,000 lbs.

Is there a specific tesile strength for A513?

I would assume that this PQR would pass because it broke away from the weld, but i need some clarification on this matter.

Im sure there is, but i dont have any specs at home.
look at the base materials MTR what were the tension test results?
sometimes they put the max and mins in the tale @ the top.
did it fail outside the HAZ?
I would look at the Specs for the base metal.
Id say ASTM513 as a spec.
google the material to get an idea if its in the range.

It depends on the type of the A513 you have it could range from 45,000 to 80,000.

I have the 2005 Edition of A 513 open in front of me. As noted, the strength depends on the Grade Designation. Strength also depends on how the tubing is made - as welded, normalized, drawn, etc.
