How Are Our TP321/321H Pipes Crafted to Last?

TP321 and TP321H seamless pipes are typically produced via cold rolling, complemented by solution annealing and pickling. This process yields uniform microstructure and a clean surface finish. TP321 and TP321H feature titanium stabilization to effectively suppress intergranular corrosion. They maintain excellent oxidation resistance and long-term structural stability even under high-temperature operating conditions. 321H features higher carbon content, making it suitable for prolonged high-temperature environments such as heating systems and heat exchangers. MTSCO's partner factories operate mature seamless pipe production lines and strictly adhere to standardized processes, ensuring every seamless pipe meets technical requirements for high-temperature applications.
