ASTM A213 TP316L is a seamless austenitic stainless steel tube specifically designed for high-temperature and high-pressure service in boilers, superheaters, and heat exchangers. The "L" grade indicates low carbon content (≤0.035%), which provides superior resistance to intergranular corrosion after welding. The addition of molybdenum (2.0-3.0%) enhances corrosion resistance, particularly against chlorides and other aggressive media.
Key Features:
1) The molybdenum content provides excellent resistance to chlorides, acids, and marine environments, outperforming TP304L in aggressive conditions
2) Suitable for high-temperature and chemical processing applications
3) Low carbon content reduces risk of intergranular corrosion
4) High weldability and formability
