The ASTM A788/A788M-17a is a standard specification for steel forgings, general requirements. This standard defines the chemical composition, mechanical properties, and other necessary requirements for steel forgings made from multiple grades of carbon and alloy steel.
The chemical composition of the A788/A788M-17a steel grade varies depending on the specific grade being used. It typically includes elements such as carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, and vanadium. The specific composition requirements are specified in the standard to ensure the desired properties and performance of the steel forgings.
The mechanical properties of the A788/A788M-17a steel grade are also specified in the standard. These properties include tensile strength, yield strength, elongation, reduction of area, and impact toughness. The steel forgings must meet these mechanical property requirements to ensure their strength and durability in various applications.
The A788/A788M-17a standard number refers to the specific version of the ASTM standard. The “17a” indicates that this is the first revision of the 2017 edition of the standard. It is important to refer to the correct standard version to ensure compliance and compatibility with other materials and processes.
Overall, the A788/A788M-17a steel grade is known for its strength and versatility, making it suitable for a wide range of applications. Its chemical composition and mechanical properties are carefully specified in the ASTM standard to ensure consistent and reliable performance.
