Introduce of TPXM-10 and S21900

TPXM10 material is a high carbon niobium chromium austenitic stainless steel. Due to the presence of stable element Nb, this material has good resistance to intergranular corrosion and intergranular stress corrosion resistance to polysulfate. In corrosive media such as acid, alkali, and salt, the corrosion resistance of TPXM 10 is similar to that of 18-8 austenitic stainless steel containing Ti. Therefore, TPXM10 is widely used in industrial fields such as boilers, power generation, petroleum, chemicals, synthetic fibers, food, and papermaking. It is particularly suitable for components such as superheater tubes, reheater tubes, large boiler steam pipelines, and petrochemical heat exchangers.

In addition, due to its high carbon content and niobium content, TPXM 10 material has relatively high creep strength, good microstructure stability, and good oxidation resistance. Although it contains a large amount of alloying elements, which may cause difficulties in cutting and processing, as well as high thermal expansion coefficient and poor thermal conductivity, when welding with dissimilar steel and using it at high temperatures, it is necessary to consider the matching of the expansion coefficient and high-temperature strength of the two materials.
