ASTM is the American Society for Testing and Materials standard, and ASTM A500 is the standard for welded steel pipe (referring to the standard specification for cold-formed welded and seamless carbon steel structural pipes for round steel and steel sections). In the international standard classification, astm+a500+/+a500 involves pipe parts and pipes, wires and cables, and steel products. In the Chinese standard classification, astm+a500+/+a500 involves steel pipes, cast iron pipes, and bare wires. A500 steel pipe piles have many different names - for square and rectangular, it is called structural pipe, or high-speed steel (or hollow structural parts). A500 products are used in applications that require load-bearing applications. Due to its aesthetic appeal, A500 is often used as a display in the Rock Hall of Fame such as the Cleveland Architectural Wonder. ASTM A500 covers cold-formed welded and seamless carbon steel round, square, rectangular, and "special" tube, electric resistance welded (ERW steel tube) carbon steel pipe for welded, riveted, or bolted construction applications.

ASTM A500 equivalent parameters: tensile strength 400mpa yield strength 310mpa
The tensile strength of astm a500 is 400MPa, and the yield strength is 290MPa, and the Chinese grade is: Q295B.
Round Structural Pipes - For steel pipes with a specified outer diameter not greater than 1.9 in (48.3 mm), the variation in outer diameter shall not exceed 0.5%, and the specific value shall not exceed 0.005 in (0.13 mm). For steel pipes with a specified outer diameter greater than 2.00 in (50.8 mm), the variation in outer diameter shall not exceed 0.75%, and the specific value shall not exceed 0.005 in (0.13 mm). The outer diameter shall be measured at least 2 in (50.8 mm) from the pipe end.
Square and Rectangular Pipes - The outer diameter shall be measured at least 2 in (50.8 mm) from the pipe end. The difference between the outer diameter of the steel pipe and the specified outer diameter shall not exceed the outer diameter variation specified in Table 3, where the variation in outer diameter includes convexity and concavity.
ASTM A500 steel pipe is welded and seamless pipe with a perimeter of 88 inches (2235 mm) or less and a wall thickness of 0.875 inches (22 mm) or less. Grade D requires heat treatment.
ASTM A500 Pressure and Strength
ASTM A500 steel plate is a low alloy structural steel plate with superior material properties and a wide range of uses. Due to its good plasticity and weldability, A500 steel plate is widely used in industries such as construction, vehicle and shipbuilding.
The strength of A500 steel plate is better than that of ordinary carbon structural steel plate, which can meet most engineering projects with high strength requirements.
Good plasticity: A500 steel plate is suitable for cold bending and cutting, and can meet the design requirements of various complex shapes.
Good weldability: A500 steel plate has good weldability and machinability, which can meet the welding and manufacturing requirements of different engineering projects.
Excellent corrosion resistance: A500 steel plate has been specially treated and has excellent corrosion resistance, which can be used for a long time in harsh environments.
Reduce engineering costs: Due to the high strength of A500 steel plate, thinner plates can be used to achieve the same strength requirements compared to ordinary carbon structural steel plates, reducing the amount and weight of materials used.
Improve engineering efficiency: The plasticity and machinability of A500 steel plate make it easier to operate and use during the production and processing process, which improves the construction efficiency of the project.
Extended service life: Due to the corrosion resistance of A500 steel plate, it can be used for a long time in harsh environments, reducing the frequency of maintenance and replacement.
