What is the maximum allowable temperature for A516 gr 70 plate?

The maximum allowable temperature for A516 Gr 70 plate is typically determined by the material's mechanical properties and its ability to resist deformation or degradation at elevated temperatures. The ASME Boiler and Pressure Vessel Code, Section II, Part D provides guidelines for determining the maximum allowable temperature for pressure vessel materials.

A516 Gr 70 plate is commonly used for moderate and lower temperature applications in pressure vessels. It is considered a carbon steel plate with good tensile strength and notch toughness. However, it has limitations at high temperatures due to potential loss of strength and reduced creep resistance.

While there is no specific universally agreed-upon maximum temperature stated for A516 Gr 70 plate, it is generally recommended to limit its use to below 538°C (1000°F). Beyond this temperature, the material may experience significant reduction in mechanical properties, including a decrease in yield and tensile strength, increased risk of deformation, and diminished structural integrity.

It is crucial to consult the relevant codes, standards, and engineering guidelines, as well as consider the specific operating conditions and requirements of the application when determining the maximum allowable temperature for A516 Gr 70 plate in a particular scenario.
