Standard Specification for Seamless Stainless Steel Mechanical Tubing and Hollow Bar
 N A511/A511M

Annotation

This specification covers seamless stainless tubing for use in mechanical applications or as hollow bar for use in the production of hollow components such as, but not limited to nozzles, reducers, and couplings by machining where corrosion-resistant or high-temperature strength is needed. The grades covered are listed in Table 1, Table 2, and Table 3.

This specification covers seamless cold-finished mechanical tubing and hollow bar and seamless hot-finished mechanical tubing and hollow bar in sizes up to 123?4 in. [325 mm] in outside nominal diameter (for round tubing) with wall thicknesses or inside diameters as required.

Tubes for mechanical applications shall be furnished in one of the following shapes, as specified by the purchaser: round, square, rectangular, or special. Tubes to be used as hollow bar shall be furnished in round shape.

Optional supplementary requirements are provided and when desired, shall be stated in the order.

The values stated in inch-pound units are to be regarded as the standard. Within the text, the SI units are shown in square brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other.

*A Summary of Changes section appears at the end of this standard
