Precision Manufacturing Process of Niobium C103 Rod & Bar
Our Niobium C103 Rod & Bar undergo a rigorous manufacturing process to ensure the highest quality and performance standards.
1. Alloy Preparation
High-purity niobium, hafnium, and titanium are precisely measured and blended according to the C103 specification (Nb-10Hf-1Ti) to ensure exact chemical composition.
2. Vacuum Arc Melting
The alloy is melted in a high-vacuum environment to eliminate gas impurities and ensure homogeneous composition, creating a uniform ingot structure.
3. Hot Forging
The ingot is heated to precise temperatures and forged to reduce cross-section, refine grain structure, and improve mechanical properties.
4. Cold Working & Annealing
Precision cold rolling or drawing achieves final dimensions with tight tolerances, followed by vacuum annealing to optimize mechanical properties.
5. Finishing & Inspection
Final grinding and polishing to achieve required surface finish, followed by comprehensive testing to ensure dimensional accuracy and material integrity.
Processing technology of C103 Rod/Bar
C103 has good plasticity and can be deformed by stamping, rolling, drawing, spinning, and bending at room temperature. The total processing rate between two annealings can reach 95%, and the processing rate of passes is 10%-50%. When the temperature rises, C103 is easy to oxidize in the air and cannot be thermally processed (such as forging, extrusion, etc.) in an unprotected state. It must be coated with an anti-oxidation coating, or in a vacuum state or in an inert gas (generally argon). ) Under protection.
Recrystallization annealing specification
C103 will absorb gas and other impurities from the environment at high temperature, causing pollution. The heat treatment should be carried out in a vacuum (vacuum ≤5×10^(-2)Pa) or under the protection of inert gas.
C103’s recrystallization annealing specification is generally:
In the vacuum state, C103 is heated to 1150-1450°C with the furnace and kept for 1-2 hours. After power-off, the temperature is cooled to no more than 60°C with the furnace before being released.
Machining performance of C103 Rod/Bar
At room temperature, C103 pipe, rod and wire can be processed by turning, milling, planing, cutting, drilling, grinding and other mechanical processing.
Welding performance of C103 Rod/Bar
C103 pipe rods and wires must be welded in an inert gas (generally argon) environment or in a vacuum state. Generally, no external welding rod is added when welding the welded pipe.
