Worldwide equivalents of grade A588 USA,AISI, ASTM, UNS

The US equivalent of the A588 is the A572. This is a high-strength low-alloy (HSLA) steel that belongs to the carbon steel family. It is a structural corrosion resistant steel with good formability and weldability. When sitting at 70 ksi, the tensile strength of the alloy increases by approximately 20%. The A572 alloy exhibits higher fracture toughness and has been widely used in bridges and buildings.

The American Iron and Steel Institute (AISI) standard for A588 is AISI 4140. This is a low alloy steel that has good resistance to high temperatures and is often used to make pipes, bolts, and shafts. The AISI 4140 alloy exhibits superior hot working, welding, and machining properties, making it ideal for a wide range of applications.

The American Society for Testing and Materials (ASTM) designation for A588 is ASTM A 514. This steel specification is an alloy of iron, manganese, and carbon, and is well-known for its yield strength and tensile strength, and its ability to resist elevated temperatures. It is commonly used in drilling tools, chassis components, bridges, and buildings, and is an excellent choice for welding applications.

The Unified Numbering System (UNS) designation for A588 is G10180. This is a high-gallium-chromium-carbon steel. It is a precipitation-strengthened material exhibiting superior mechanical properties and excellent resistance to elevated temperatures. It is commonly used in applications that require high levels of tensile and yield strength, such as aircraft components and structural components.

The global equivalent of A588 is S355J2W+N. This grade is a structural steel that has excellent corrosion resistance due to its high chromium and molybdenum content. It is an unalloyed steel used in various construction applications. It has a minimum tensile strength of 470-630 MPa and a yield strength of 355 MPa. It is easy to form and weldable, making it a popular choice in bridges and buildings.
