Q:What are the common general-purpose grades of carbon steel pipes?

Internationally, carbon steel plates primarily adhere to mainstream standard systems from the United States, Europe, and Japan. The American ASTM A36 is a common general-purpose structural steel with excellent weldability and formability, widely used in construction and bridges. High-quality carbon steels typically use the AISI/SAE series, such as AISI 1020 or 1045, for manufacturing mechanical components. Structural steels like S235 and S355 in the European standard system, where the numbers denote minimum yield strength, are commonly employed in various engineering projects. Japanese designations like SS400 (structural steel) and S45C (mechanical structural steel) are also widely circulated in Asia. Additionally, specialized grades exist for specific applications, such as pressure vessel steel ASTM A516 and cryogenic steel ASTM A537, meeting stringent requirements in energy, chemical, and other sectors.
