Scope: ASTM A105 is a widely recognized standard specification that covers forged carbon steel components used primarily for high-temperature and high-pressure service in various pressure systems. These components include but are not limited to flanges, fittings, valves, and similar parts. The specification sets forth the requirements for the chemical composition, mechanical properties, heat treatment, manufacturing processes, testing, and marking of these carbon steel forgings.
Material Grade: ASTM A105 is typically available in two grades, Grade 1 and Grade 2, which are differentiated by their mechanical properties and impact testing requirements. These grades are designed to meet specific performance criteria for various applications. Chemical Composition: The chemical composition of ASTM A105 carbon steel forgings is closely monitored to ensure its suitability for use in demanding environments. Typical composition includes a maximum carbon content of 0.35%, manganese ranging from 0.60% to 1.05%, and maximum limits for phosphorus (0.035%), sulfur (0.040%), and copper (0.40%). Heat Treatment: The forgings may undergo different heat treatment processes depending on their application and grade. Common heat treatment methods include normalization and tempering, quenching and tempering, or simply normalization. The choice of heat treatment method is based on achieving the desired mechanical properties and structural integrity.

Mechanical Properties: ASTM A105 sets forth specific mechanical property requirements, including tensile strength, yield strength, elongation, and reduction of area. The typical tensile strength ranges from 70 to 95 ksi, while the yield strength can vary between 36 and 70 ksi. The material should also exhibit a minimum elongation of 22% and a minimum reduction of area of 30%. Size Range: Carbon steel forgings manufactured under this specification are typically available in sizes up to 24 inches (600 mm) in diameter. However, larger sizes may be available upon request to suit specific project requirements. Pressure and Temperature Ratings: Pressure and temperature ratings for components forged to ASTM A105 are determined by referencing other industry standards such as ASME B16.5 for flanges and ASME B16.34 for valves. These standards provide detailed tables specifying pressure-temperature ratings for various materials and classes. Testing and Inspection: ASTM A105 requires rigorous testing and inspection procedures, including radiographic or ultrasonic examination, mechanical tests, and nondestructive tests, in accordance with ASME B16.5 and ASME B16.34 standards. These tests are essential to ensure the quality and integrity of the forgings.
