ASTM A787 covers carbon steel grades starting at 1008 up through 1021. Please visit our
Finishes & Chemistries
page for a listing of our standard chemistry capabilities.
As a standard, Valmont applies a recoating of the weld seam area after welding for types 1, 2 and 4. If no recoating of the weld seam is requested, please provide that information at time of quote and order placement.
Physical testing (yield, tensile and elongation) is not required under A787. If there is a specific strength requirement for your application, please be sure to include at the time of inquiry as that will affect the chemistry required.
Flash control
of the ID weld bead is discussed in section 7.1 to 7.1.3 of the specification. Valmont produces tubing to flash control 0.015" maximum, 0.010" maximum, 0.005" maximum and flash in.
ASTM A513
is a related mechanical tubing specification that covers non-metallic coated carbon and alloy steel tubing. Please refer to the ASTM A513 page for more information.
