C103 Tube, Rod, Wire
C103 has Tubes, Rods, Wires and other shapes, which can be processed by extrusion, forging, rolling and drawing. It is usually supplied in the recrystallization annealing state, stress relief annealing state and cold working state.
| Types | Standard | Range of Supply（Diameter）/mm |
| Forged, extruded, rolled and ground (turned) bars | CB/T 14842 | 3-65 |
| Rolling, swaging or drawing rods, wires | ASTM B392 | 0.5-63.5 |
| Cold rolled or cold drawn seamless pipe | GB/T 8183 | 3-50 |
| Extruding, rolling, swaging or drawing pipe | ASTM B394 | <100 |
Processing technology of C103 Tube/Pipe
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 Tube/Pipe
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 Tube/Pipe
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.
