  2. Cold working - Wikipedia

    en.wikipedia.org/wiki/Cold_working

    In metallurgy, cold forming or cold working is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature.. Such processes are contrasted with hot working techniques like hot rolling, forging, welding, etc. [1]: p.375 The same or similar terms are used in glassmaking for the equivalents; for example cut glass is made by "cold ...

  3. Cold-formed steel - Wikipedia

    en.wikipedia.org/wiki/Cold-formed_steel

    When steel is formed by press-braking or cold rolled forming, there is a change in the mechanical properties of the material by virtue of the cold working of the metal. When a steel section is cold-formed from flat sheet or strip the yield strength, and to a lesser extent the ultimate strength, are increased as a result of this cold working ...

    A draw bench is a machine used to do cold work on a metal, such as changing the shape of the metal without applying heat and applying only pressure. Machine construction

  6. Tool steel - Wikipedia

    en.wikipedia.org/wiki/Tool_steel

    A cold work steel used for gauges, cutting tools, woodworking tools and knives. It can be hardened to 66 HRC, typically used at 61-63 HRC. Also sold as 1.2842 and 90MnCrV8. [9] O6: 1.45% C, 1.0% Mn, 1.0% Si, 0.3% Mo: A cold work graphitic steel with outstanding resistance to metal-to-metal sliding wear and galling.

  7. Annealing (materials science) - Wikipedia

    en.wikipedia.org/wiki/Annealing_(materials_science)

    Hot working or cold working after the annealing process alters the metal structure, so further heat treatments may be used to achieve the properties required. With knowledge of the composition and phase diagram , heat treatment can be used to adjust from harder and more brittle to softer and more ductile.

  8. Hubbing - Wikipedia

    en.wikipedia.org/wiki/Hubbing

    As the metal flows the face of the die block is deformed, and, generally, must be machined flat. The die block is often a cylinder that is reinforced with a surrounding steel ring during the hubbing process. Hubbing is usually less expensive than die sinking, i.e., machining the female die, and multiple dies can be made from the male hub.

  9. Wire drawing - Wikipedia

    en.wikipedia.org/wiki/Wire_drawing

    [1] [2] The process of wire drawing changes material properties due to cold working. The area reduction in small wires is generally 15–25% and in larger wires is 20–45%. [1] The exact die sequence for a particular job is a function of area reduction, input wire size and output wire size. As the area reduction changes, so does the die ...
