CTIA’s TZM Alloy Piercing Plug

1. What's TZM Alloy Piercing Plug?
TZM Alloy Piercing Plug (Titanium Zirconium Molybdenum Alloy Piercing Plug) is high-temperature seamless steel tube hot piercing tool manufactured from high-purity molybdenum raw materials. It uses molybdenum (Mo≥99.95%) as the matrix and incorporates titanium (Ti: 0.40%–0.55%), zirconium (Zr: 0.06%–0.12%), and carbon (C: 0.01%–0.04%) to form TiC and ZrC dispersion-strengthened phases, improving comprehensive performance under high-temperature, high-pressure, and severe friction conditions. CTIA’s TZM alloy piercing plug provides excellent high-temperature strength, creep resistance, thermal shock resistance, and deformation resistance, making it an important high-temperature tooling material for seamless steel tube hot piercing processes.

2. Advantages of CTIA’s TZM Alloy Piercing Plug
(1) Excellent high-temperature strength retention: Melting point of approximately 2620°C, maintaining high strength under steel tube piercing temperatures to reduce deformation.
(2) Excellent thermal shock resistance: Low coefficient of thermal expansion of approximately 5.5–5.9×10⁻⁶/K, withstanding thermal stresses caused by repeated heating and cooling cycles.
(3) Good wear resistance: TiC and ZrC dispersion-strengthened phases improve hardness and structural stability, reducing high-temperature friction and wear.
(4) Strong creep resistance: Strengthening phases effectively inhibit dislocation movement and grain boundary sliding, extending service life under long-term high-temperature operation.
(5) High machining accuracy: Supports precision machining of tapered surfaces, curved surfaces, and complex profiles to meet different piercing process requirements.

3. Applications of CTIA’s TZM Alloy Piercing Plug
CTIA’s TZM alloy piercing plug is used in: (1) seamless steel tube hot piercing production lines; (2) piercing of alloy steel tubes, stainless steel tubes, and high-temperature alloy tubes; (3) hot-rolled seamless steel tube manufacturing equipment; (4) special steel tube and difficult-to-machine material piercing processes.
