What are the different grades available in ASTM A516

ASTM A516 is a specification that covers carbon steel plates used for pressure vessel applications. It includes several different grades, each designed to meet specific requirements. Here are some of the grades available in ASTM A516:

1. ASTM A516 grade 60: ASTM A516 grade 60 is a widely used grade known for its excellent notch toughness and weldability. It has a minimum tensile strength of 415 MPa (60,000 psi) and a minimum yield strength of 220 MPa (32,000 psi).

2. ASTM A516 grade 65: ASTM A516 grade 65 offers improved notch toughness compared to grade 60 and is suitable for moderate to lower temperature service. It has a minimum tensile strength of 450 MPa (65,000 psi) and a minimum yield strength of 240 MPa (35,000 psi).

3. ASTM A516 grade 70: ASTM A516 grade 70 is a high-strength carbon steel grade primarily used for high-temperature service. It has a minimum tensile strength of 485 MPa (70,000 psi) and a minimum yield strength of 260 MPa (38,000 psi). grade 70 is popular in applications such as oil refineries, petrochemical plants, and power generation.

These are just a few examples of the grades available in ASTM A516. Other specialized grades, such as HIC-resistant grades or dual-certified grades, may also be available to meet specific project requirements.
