5. Cold drawing process
  • Cold drawing, a metalworking process which uses tensile forces to stretch metal. For pipe, line, bar and tube drawing the stock is drawn through a die to reduce its diameter and increase its length. Cold drawn or cold drawing is usually done at room temperature, which is classified as a cold working process.
  • Tube cold drawing or cold drawn process is mainly used to decrease the diameter, improve surface finish and improve dimensional accuracy. A mandrel may or may not used depending on the specific process used.
  • Drawing can also be used to produce a cold formed shaped cross-section. Cold drawn cross-sections are more precise and have a better surface finish than hot extruded parts. Inexpensive materials can be used instead of expensive alloys for strenth requirements, due to work hardening.
6. Annealing process
  • Annealing is a heat treatment, causing changes in its properties such as hardness and ductility, which is important in shaping and creating a more refined piece of work through process such as rolling, drawing, forging, spinning, extruding and heading. The annealing process on mechanical parts, steel pipes, steel tubes can be used to ensure there is reduced risk of distortion of the work piece during machining, welding, or further heat treatment cycles.
  • Annealing occurs by the diffusion of atoms within a solid material, so that the material progresses towards its equilibrium state.Heat is needed to increase the rate of diffusion by providing the energy needed to break bonds. The movement of atoms has the effect of redistributing and destroying the dislocations in metals and (to a lesser extent) in ceramics. This alteration in dislocations allows metals to deform more easily, so increases their ductility
  • Annealing is usually used to induce ductility, soften material, relieve internal stresses, refine the structure by making it homogeneous and improve cold working properties.
  • Mechanical properties, such as hardness and ductility, change as dislocations are eliminated and the metal's crystal lattice is altered. On heating at specific temperature and cooling it is possible to bring the atom at the right lattice site and new grain growth can improve the mechanical properties.
