YOUFASS specializes in fabricating titanium-stabilized austenitic channels planned for requesting mechanical situations. With 15 generation lines and 50,000 tons of yearly capacity, we offer total measure ranges from NPS 1/8" to 48" in both consistent and welded designs. Our pipes meet strict ASTM A312/A312M-22 measures, sponsored by ISO 9001 and PED certifications. Whether you require Sch 5S or Sch XXS divider thickness, each pipe experiences arrangement toughening and thorough testing to guarantee reliable quality for your basic applications.

What Makes TP321 and TP321H Special?

TP321 and TP321H grades have a place to the titanium-stabilized family of austenitic stainless steels. The expansion of titanium anticipates chromium carbide precipitation amid welding and high-temperature introduction. This stabilization keeps your channeling frameworks solid and corrosion-resistant indeed after a long time of service.

You'll discover these grades especially important when working at temperatures between 800°F and 1500°F. The "H" variation contains higher carbon substance (0.04–0.10% vs. 0.08% max), which improves crawl quality for drawn out elevated-temperature operations.

Frequently Asked Questions

Q:What is TP321 stainless steel pipe?

A:TP321 is a titanium-stabilized austenitic stainless steel (similar to 304 grade) specifically designed for high-temperature service. The titanium addition prevents carbide precipitation, making it ideal for applications between 800°F and 1500°F.

Q:What is the difference between 321 and 321H?

A:The primary difference lies in carbon content. TP321H contains higher carbon (0.04–0.10%) compared to TP321 (0.08% max). This gives 321H improved high-temperature creep strength, making it better suited for prolonged elevated-temperature operations in pressure vessels and boilers.

Q:Where are TP321 pipes used?

A:You'll find TP321 pipes in aerospace components, heat exchangers, industrial furnace parts, exhaust systems, expansion joints, petrochemical processing equipment, and power generation facilities—anywhere that combines high temperature with corrosion concerns.
