A500 Pipe Grades
ASTM A500 is the standard specification for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. A500 pipe is available in four grades, each with different mechanical property requirements to suit a variety of structural applications.
| Grade | Min. Yield Strength | Min. Tensile Strength | Common Use |
|---|---|---|---|
| Grade A | 33 ksi (228 MPa) | 45 ksi (310 MPa) | General structural use |
| Grade B | 42 ksi (290 MPa) | 58 ksi (400 MPa) | Most widely specified grade |
| Grade C | 46 ksi (317 MPa) | 62 ksi (427 MPa) | Higher strength applications |
ASTM A500 Grade B pipe is the most commonly specified grade in structural steel applications due to its balance of strength, weldability, and availability. Saginaw Pipe stocks A500 Grade B pipe in a wide range of sizes and can assist with other grades upon request.

Frequently Asked Questions About A500 Pipe
ASTM A500 is a standard specification published by ASTM International that covers cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular cross sections. A500 pipe is commonly used in structural applications where strength, weldability, and dimensional consistency are required.
The primary difference is yield and tensile strength. ASTM A500 Grade B pipe has a minimum yield strength of 42 ksi and tensile strength of 58 ksi, making it stronger than Grade A, which has a minimum yield strength of 33 ksi and tensile strength of 45 ksi. Grade B is the most commonly specified grade for structural steel applications.
Yes. ASTM A500 pipe is a form of structural steel tubing. While it is sometimes referred to as pipe, it is technically classified as structural tubing and is designed to meet specific mechanical and dimensional requirements for use in load-bearing applications.
Yes. ASTM A500 steel pipe is readily weldable using standard welding processes. It is commonly welded in structural fabrication and construction applications. Proper preheat and welding procedures should be followed based on wall thickness and project specifications.
