ASTM A178 Grade A

Note 1 — Type C and D tubes are not suitable for safe-ending for forge welding. Minimum elongation values are also given. Within the text, the SI units are shown in brackets. Crush test shall also be performed if asked by the purchaser. This specification covers standards for electric-resistance-welded tubes with minimum-wall-thickness made of carbon steel and carbon-manganese steel to be used in boiler atsm, boiler flues, superheater flues, and safe ends.

ASTM A178 and ASME SA178 Carbon Steel Tubes

Manufacturing processes must include heat treatment, welding after cooling. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Link to Active This link will always route to the current Active version of the standard.


The steel shall conform to stated compositions of carbon, manganese, phosphorus, sulphur, and silicon. Please feel free to contact us! Steel Grades A low-carbon steelC medium-carbon steelor D carbon-manganese steel.

The steel shall be of Grades A low-carbon steelC medium-carbon steelor D carbon-manganese steel. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

Combining values from the two systems may result in nonconformance with the specification. This abstract is a brief summary of the referenced standard.
