ASTM A500 is a specification established by the American Society for Testing and Materials (ASTM) for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is commonly used for structural purposes due to its high strength and versatility. The A500 standard defines tolerances, properties, and dimensional characteristics for the tubing.
The ASTM A500 carbon steel pipe or tube is commonly used in construction and structural applications. It’s suitable for framing, construction of bridges, buildings, and for general structural purposes.
This specification is divided into different grades, each with different properties. They include:
- Grade A: Has basic minimum yield strength of 39,000 PSI (269 Mpa) and can be used for many applications.
- Grade B: Has higher strength and used for structural applications.
- Grade C: Has highest strength and is often used for more demanding applications.
- Grade D: Is a high-strength, low-alloy (HSLA) grade suitable for more demanding applications.
