Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the 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.

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 specification is expressed in both inch-pound units and in SI units; however, unless the purchase order asttm the applicable M specification designation SI unitsthe inch-pound units shall apply.

This abstract is a brief summary of the referenced standard. Carbon Steel A Tube Exporter.

This guide covers standard specification for round, square, rectangular, and special shape, electric-resistance-welded mechanical tubing, either zinc-coated galvanized after welding or produced from aluminum-coated, zinc-coated galvanizedzinc-iron alloy-coated galvannealedor aluminum-zinc alloy-coated steel sheet.

Combining values from the two systems may result in non-conformance with the standard. Wall thickness tolerances for premetallic coated as-welded tubing and diameter tolerances for metallic-coated round tubing shall be provided.

Sizes outside the ranges listed above may be ordered provided all satm requirements of the specification are met. Low-carbon steels and other carbon steels shall conform to the required chemical composition for carbon, manganese, phosphorus, and sulfur. 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.

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.

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 Combining values from atsm two systems may result in non-conformance with the standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
