ASME SA213 TP316L Stainless Steel Seamless Heat Exchanger Tube For Power Generation
ASME SA213 TP316L Stainless Steel Seamless Heat Exchanger Tube For Power Generation
Grade TP316L is a low-carbon austenitic stainless steel with excellent corrosion resistance, especially against sulfuric and chloric acids.
This material offers excellent corrosion resistance, good weldability, and high and low-temperature performance, making it commonly used in the chemical processing, petrochemical, pharmaceutical, food and beverage, and marine industries. TP316L exhibits good tensile strength, ductility, and weldability. Its low carbon content reduces the risk of carbide precipitation during welding, maintaining corrosion resistance in the heat-affected zone.
ASME SA213 outlines the standards for seamless and welded tubes intended for high-pressure and high-temperature service. The specification ensures that the tubes meet stringent quality and performance criteria.
