Carbon steel grades ASTM SA 516 Grades 60 and 70 are typically utilized in the building of boilers and pressure vessels. These grades are highly respected because of their superior mechanical qualities and ability to withstand cracking caused by hydrogen, which makes them appropriate for usage in high-pressure settings. The "BQ" designation usually denotes the "Bleed-Quench" heat treatment, which improves the ductility and toughness of steel. The minimum yield strength of ASTM SA 516 Grade 60 is 35,000 psi (240 MPa), and the minimum tensile strength is 70,000 psi (485 MPa). It is a popular option for pressure vessels in areas where temperatures might fluctuate because it provides good weldability and notch toughness at moderate temperatures. This grade is frequently used in the chemical, oil, and gas sectors where the material must be able to endure high temperatures and pressures without failing.
Higher minimum yield strength of 40,000 psi (275 MPa) and minimum tensile strength of 70,000 psi (485 MPa) are provided by ASTM SA 516 Grade 70. It is renowned for having greater mechanical qualities than Grade 60, providing more resistance to cracking and enhanced performance at higher temperatures. In more demanding situations where greater strength and dependability are needed, this grade is especially preferred.
These materials are used to create flanges that are utilized in a variety of industrial applications to join pipes, valves, and other equipment. They are compatible with a variety of systems since they are available in multiple standards, including ANSI, DIN, and JIS. By increasing their toughness and decreasing their brittleness, the "BQ" treatment given to these flanges improves their capacity to withstand the stresses of high-pressure and high-temperature operations.
