304L, 304H, and 304LN, which have different chemical compositions
and properties.
What are the different standards for 304 stainless steel tubes?
The different standards for 304 stainless steel tubes include ASTM
A269, ASTM A213, and EN 10216-5, which specify the requirements for
the manufacturing, testing, and quality control of the tubes.
What is the weight of 304 stainless steel tubes?
The weight of 304 stainless steel tubes depends on the size, wall
thickness, and length of the tubes. A 1-inch diameter tube with a
wall thickness of 0.065 inches and a length of 10 feet weighs
approximately 2.5 pounds.

Surface Finish
| Characteristics & Application |
| Hot-rolled surface, annealed and pickled, can be used as
cold-rolling material,industial tanks and chem i cal devices. |
