Introduce of TPXM-10 and S21900

TPXM-10 (S21900) is a multifunctional super austenitic stainless steel with high yield strength and good corrosion resistance. The initial characteristics of TPXM-10 are high strength under annealing conditions, excellent corrosion resistance at high temperatures, and easy welding and processing capabilities. Due to these features, they are used in many aviation applications. TPXM-10 can achieve both high strength and toughness even at temperatures below -254 ° C, making it ideal for use at freezing temperatures.

Firstly, the composition and structure of TPXM-10 (S21900) austenitic stainless steel are the basis for its performance. This type of stainless steel is mainly composed of elements such as iron, chromium, and nickel, among which the chromium content determines its basic corrosion resistance. After heat treatment, TPXM-10 (S21900) has an austenitic phase in its structure, which is a stable, non-magnetic structure that can achieve high strength and excellent corrosion resistance. Enable the material to maintain stable performance in various environments. S21900 maintains good stability in acidic, alkaline, and neutral environments and exhibits good corrosion resistance in various corrosive media. Therefore, it is widely used in fields such as chemical engineering and marine engineering.

Secondly, TPXM-10 (S21900) super austenitic stainless steel is a multifunctional austenitic stainless steel that still has good stability in high and low temperature environments, and can maintain high strength and toughness even at temperatures below zero degrees Celsius. It can resist stress corrosion cracking in marine environments and provide good high-temperature oxidation resistance. Even at low temperatures, S21900 super austenitic stainless steel remains non-magnetic.

Annealing is used to provide excellent stress rupture life and operating temperatures between 1300/1600 degrees. Hot working heating should be within the temperature range of 2100 ° F to 2200 ° F. Annealing during manufacturing can be completed between 1950 ° F and 2050 ° F.

Finally, the mechanical properties of TPXM-10 (S21900) austenitic stainless steel are also the key to its widespread application. TPXM-10 has a carbon content of 0.13%, which can achieve the high hardness of HRC33 while maintaining high toughness, good processability, and welding performance. This type of stainless steel has high strength and toughness, as well as good ductility and plasticity. This enables TPXM-10 to exhibit good stability under external forces, making it less prone to fracture or deformation
