List of high-quality authors SUS347 Stainless Steel: Austenitic stainless steel that is resistant to carbonization and stabilized.
SUS347 is a titanium and tantalum-stabilized austenitic stainless steel that achieves superior performance in high-temperature environments through a clever combination of alloying elements. Its carbonization resistance, resistance to high-temperature oxidation, and superior resistance to intergranular corrosion make it highly sought after in a wide range of industrial applications.

SUS347 uses an alloying strategy of titanium and tantalum to effectively resist carbonization precipitation when welded and intermittently heated to 800 1650 °F (427 899 °C). Because tantalum and titanium have a higher affinity for carbon than chromium, the carbides precipitate randomly inside the grains rather than forming a continuous pattern at the grain boundaries. This property helps to improve the corrosion and oxidation resistance of SUS347.
SUS347 not only has excellent carbonization resistance, but also excellent high-temperature oxidation stability. In high-temperature environments, its anti-oxidation film effectively protects the surface of the material and prolongs its service life. This makes the SUS347 ideal for use in high-temperature and high-pressure applications, such as petrochemical, electric power, and other fields.
Compared to typical Type 18-8 alloys, SUS347 has excellent resistance to intergranular corrosion at high temperatures. Its stable austenite structure and special carbonization precipitation method make it more reliable in complex corrosive environments, and are suitable for chemical, pharmaceutical and other fields.
SUS347 is widely used in fields requiring high temperature and high pressure, corrosion resistance and carbonization resistance. In the nuclear industry, chemical equipment, aerospace and other fields, SUS347 provides engineers with reliable solutions. Its excellent properties make it the material of choice for extreme conditions.
SUS347 stainless steel performs well in high-temperature and high-pressure environments due to its stable austenitic structure, carbonization resistance, high-temperature oxidation resistance, and excellent intergranular corrosion resistance. Its wide application in many fields proves its importance in the field of engineering, and indicates that it will continue to play an important role in the field of superalloys in the future.
