ASTM A376 TP347 Stainless Steel Tube For High-Temperature Heat Exchangers
Specifications
ASTM A376 TP347 is a specification for seamless austenitic steel tubes stabilized with Niobium (Columbium), designed for high-temperature service. This stabilization provides superior resistance to intergranular corrosion and enhances high-temperature strength.
ASTM A376 TP347 tubing is primarily specified for high-temperature, high-pressure services and welded assemblies where superior intergranular corrosion resistance and high creep strength are paramount, such as in power generation and petrochemical heating equipment.
