CTIA’s TZM Molybdenum Alloy Piercing Plug

1. What's TZM Molybdenum Alloy Piercing Plug?
TZM Molybdenum Alloy Piercing Plug (Titanium Zirconium Molybdenum Piercing Plug) is high-temperature tooling specially designed for seamless steel tube hot piercing, manufactured using high-purity molybdenum (Mo≥99.95%) as the base material. The molybdenum matrix is alloyed with titanium (Ti: 0.40%–0.55%), zirconium (Zr: 0.06%–0.12%), and carbon (C: 0.01%–0.04%) to form stable TiC and ZrC dispersion-strengthened phases. CTIA GROUP manufactures TZM alloy piercing plugs through optimized composition and precision machining processes, ensuring excellent high-temperature strength, deformation resistance, and wear resistance for seamless steel tube hot piercing applications under high-temperature, high-pressure, and high-friction conditions.

2. Advantages of CTIA’s TZM Molybdenum Alloy Piercing Plug
(1) High-temperature load capacity: High melting point of approximately 2620°C, maintaining excellent strength and rigidity during high-temperature steel tube piercing.
(2) Excellent thermal deformation resistance: TiC and ZrC strengthening phases improve high-temperature stability and effectively reduce deformation under long-term heat and pressure exposure.
(3) Good thermal fatigue resistance: Low coefficient of thermal expansion of approximately 5.5–5.9×10⁻⁶/K reduces thermal stress and crack risks during repeated heating and cooling cycles.
(4) Stable wear resistance: Uniformly distributed carbide strengthening phases improve surface wear resistance and withstand high-speed friction during piercing operations.
(5) High structural machining accuracy: Head geometry, cone angle, and dimensions can be customized according to piercing machine parameters, and process conditions to improve piercing stability.

3. Applications of CTIA’s TZM Molybdenum Alloy Piercing Plug
CTIA’s TZM molybdenum alloy piercing plug is used in: (1) seamless steel tube hot piercing; (2) alloy steel tube piercing production; (3) hot processing of stainless steel tubes and high-temperature alloy tubes; (4) continuous hot rolling production of special steel tubes.
