What is the yield strength of ASTM A500 Grade B pipe?
ASTM A500 is a standard for cold-formed welded carbon structural steel tubing developed by the American Society for Testing and Materials (ASTM), which sets forth clear technical requirements for rectangular and square tubes. According to the standard, the yield strength of such steel tubing must reach or exceed 345 MPa (approximately 50 ksi), the tensile strength must range from 400 to 550 MPa, and the elongation must be no less than 18%. These mechanical properties ensure that the steel tubing possesses sufficient structural stability when subjected to loads.
What is ASTM A500 Grade B equivalent material?
A500 is a common structural carbon steel used in ASTM applications, possessing good strength and weldability. It is characterized by moderate manganese content and strict control over sulfur and phosphorus impurities, making it suitable for cold bending. This type of steel is widely used in building frames, bridge supports, and similar applications, and is equivalent to the commonly used Q355 series steel in China.
