This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order specifies the applicable M specification designation SI unitsthe aztm units shall apply. ASTM A Type 4 welded mechanical tubing is produced using carbon steel that has been pre-coated with a thin layer of zinc while in coil form and then heat treated to convert the coating into a zinc-iron alloy.

The steels shall conform to elemental tolerances for product analysis. Outside Diameter Tange, in. Sizes outside the ranges listed above may be ordered provided all other requirements of the specification are met. ASTM A Type 6 welded mechanical tubing is produced using steel that has been pre-coated with a thin layer of a zinc-aluminum-magnesium alloy coating while in coil form as specified in ASTM A A Type 6 Tubing provides a high degree of corrosion resistance and an excellent surface appearance and is a bridge between stainless and hot-dip galvanized finishes.

This abstract is a brief summary of the referenced standard. We manufacture of ASTM A TYPE 1 Tubingis produced using aluminized steel which is carbon steel that has been pre-coated on both sides with an aluminum silicon alloy while in coil form. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Wall thickness tolerances for premetallic coated as-welded tubing and diameter tolerances for metallic-coated round tubing shall be provided.

Combining values from the two systems may result in non-conformance with the standard. ASTM A Type 3 welded mechanical tubing is produced out of a hot rolled carbon steel and then is hot-dip galvanized per ASTM A specification into a tank of molten zinc after the tubing is already formed and welded.
