ASTM A182 F316L Stainless Steel Heat Exchanger Tubesheet

ASTM A182 specifies requirements for forged or rolled alloy steel and stainless steel flanges, forged pipe fittings, valves, and valve components for high-temperature and high-pressure service. Material grades covered by this standard, such as F316L, are widely used in the manufacture of forgings for pressure-containing equipment, including tubesheets. Tubesheets, a critical pressure-containing component in heat exchangers and pressure vessels, are typically machined from thick plate or forged stock. When forgings are used to manufacture tubesheets, ASTM A182 is one of the most commonly used material standards.
