A36 and A516 are both carbon steel grades, but they have different applications and properties. Here's a comparison between A36 and A516:
A36 Steel:
Application: A36 is a widely used general-purpose carbon steel grade suitable for structural applications. It is commonly used in construction, machinery, and manufacturing industries.
Mechanical Properties: A36 has a minimum yield strength of 250 MPa (36 ksi) and a minimum tensile strength of 400 MPa (58 ksi). It offers good ductility and can be easily welded, machined, and formed.
A516 Steel:
Application: A516 is specifically designed for pressure vessel applications and is primarily used in the oil, gas, and petrochemical industries. It is intended for use in moderate to low-temperature environments that require notch toughness.
Mechanical Properties: A516 has different grades with varying tensile strength and yield strength levels, such as A516 Grade 70, which is one of the most commonly used grades. A516 Grade 70 has a minimum tensile strength of 485 MPa (70 ksi) and a minimum yield strength of 260 MPa (38 ksi). It is known for its excellent notch toughness and resistance to brittle fracture.
A36 is a general-purpose carbon steel grade suitable for structural applications, while A516 is specifically designed for pressure vessel applications and offers superior notch toughness. The selection between A36 and A516 depends on the specific application requirements, including the operating temperature, pressure, and need for notch toughness. It is important to refer to the relevant specifications and consult with engineers or experts to determine the appropriate grade for a particular project.
