The A515/A515M-17 steel grade is a high-strength, low-alloy steel that is commonly used in pressure vessels and boiler applications. It is composed primarily of iron, with small amounts of carbon, manganese, phosphorus, sulfur, silicon, and copper.
The mechanical properties of this steel grade are impressive, with a minimum yield strength of 415 MPa (60 ksi) and a minimum tensile strength of 485 MPa (70 ksi). It also has a good elongation and impact resistance. These properties make A515/A515M-17 a reliable choice for applications that require high strength and toughness.
The standard number for A515/A515M-17 is ASTM A515/A515M-17, which is the American Society for Testing and Materials (ASTM) specification for pressure vessel plates, carbon steel, for intermediate- and higher-temperature service. This standard specifies the requirements for chemical composition, mechanical properties, and other relevant considerations for the A515/A515M-17 steel grade.
When selecting a steel grade for a specific application, it is important to consider the corresponding standards, such as ASTM A515/A515M-17, to ensure that the material meets the necessary criteria for safety and performance. By following the guidelines and specifications outlined in the corresponding standard, engineers and manufacturers can confidently utilize the strength and versatility of the A515/A515M-17 steel grade in their designs and applications.
