ASTM International has announced a new A554 - 11 standard specification for welded stainless steel mechanical tubing.

This guide covers standard specification for welded stainless steel tubing for mechanical applications where appearance, mechanical properties, or corrosion resistance is needed. The tubes shall be made from flat rolled steel by an automatic welding process without the addition of filler metal.

Tubes shall be furnished in one of the following shapes like round, square, rectangular, or special. Heat analysis shall be performed wherein several grades of steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, titanium, columbium and tantalum.

This abstract is a brief summary of the referenced standard. 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. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

This specification covers welded austenitic and ferritic stainless steel mechanical tubing intended for use in ornamental, structural, exhaust, and other applications where appearance, mechanical properties, or corrosion resistance is needed.

This specification covers as welded or cold reduced mechanical tubing in sizes to 16 inches (406.4 mm) outside dimension, and in wall thicknesses 0.020 inches (0.51 mm) and over.

Tubes shall be furnished in one of the following shapes as specified by the purchaser: round, square, rectangular, or special.

Supplementary requirements of an optional nature are provided and when desired shall be so stated in the order.

The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
