ASTM A500, carbon steel, cold formed welded and seamless structural tube
Alloy Pipe, Black steel pipe, ASTM A500,
The pipe is manufactured without a seam, making it a better pipe to carry gas. The black steel pipe is also used for fire sprinkler systems because it is more fire-resistant than galvanized pipe.
The black steel pipe is also used for fire sprinkler systems because it is more fire-resistant than galvanized pipe. Another related standard is ASTM A501, which is a hot-formed version of this A500. ASTM A500 defines four grades of carbon steel based primarily on material strength.
This is a standard set by the standards organization ASTM International, voluntary standards development organizations that sets technical standards for materials, products, systems, and services.
Applications are for structural use as in bridges, buildings or general structural use. The alloy may be welded, bolted or riveted for construction purposes.
This is a simple carbon steel alloy and is readily machined by conventional means. It is similar to 1027 steel in machining characteristics.
Forming is readily accomplished by conventional methods.
The alloy is weldable by all of the standard methods.
Not applicable. The product is used in the “as supplied” condition and may be annealed or stress relieved by the supplier as supplied.
Product is supplied in piping form and is not subsequently forged.
No data. Generally hot forming would not be done. Contact the steel supplier for additional information.
Cold works readily by conventional methods.
A500 cold-formed tubing comes in four grades based on chemical composition, tensile strength, and heat treatment. The yield strength requirements are higher for square and rectangular than for round tubing. The minimum copper content is optional. Grade D must be heat treated.
