ASTM A213 TP347 1.4550 Seamless Tube For Boiler And Heat Exchanger

TP347 stainless steel is a type of austenitic stainless steel. It improves its resistance to intergranular corrosion in high temperature environments by adding a certain amount of stabilizing elements (such as niobium and titanium). This stainless steel not only inherits the excellent corrosion resistance, good processability and weldability of austenitic stainless steel, but also significantly enhances its strength and stability under high temperature conditions due to the addition of stabilizing elements. It is especially suitable for working environments with temperatures up to 800°C.

The reason why TP347 seamless stainless steel pipe stands out among many stainless steel materials is mainly due to its performance advantages in the following aspects:

first, its excellent high temperature resistance enables it to maintain a stable working state under extremely high temperature conditions;

second, its good corrosion resistance, whether it is to oxidizing media or reducing media, shows excellent resistance;

third, its excellent resistance to stress corrosion cracking effectively extends the service life of the pipeline system;

finally, its good processability and weldability make the material more flexible and changeable in the processing and manufacturing process, meeting the use requirements under different working conditions.
