ASTM stands for the American Society for Testing and Materials, which is now known as ASTM International. When referring to an ASTM stainless steel tube, it indicates that the tube conforms to specific standards set by ASTM for stainless steel materials.

ASTM has established various standards for stainless steel tubes, such as ASTM A213/A213M (seamless tubes), ASTM A269/A269M (welded and seamless tubes), and ASTM A554 (ornamental tubes). These standards define the requirements for dimensions, mechanical properties, chemical composition, and other characteristics of stainless steel tubes.

It’s important to note that there are different grades of stainless steel, such as 304, 316, 321, etc., each with its own unique properties and applications. The specific grade of stainless steel used in a tube will depend on the intended use and the requirements of the application.

When looking for an ASTM stainless steel tube, it’s advisable to specify the required standard, grade, dimensions, and any additional specifications to ensure you get the appropriate product for your needs.

Stainless steel tubing is typically measured by its outer diameter and can be used in a variety of applications including a number of structural applications.
