A process in which steel, in the form for example of bar, rod, tube, section or wire, is reduced in cross-sectional area and so increased in length by being pulled through a die. Initially, the steel is at room temperature but the reduction process may cause a noticeable increase in the temperature of the drawn steel. Cold drawing increases strength but reduces ductility and toughness.
The mechanical work process of drawing tubular products through a hardened die while at room temperature. Usually done with a supporting mandrel (drawn over mandrel) to reduce the O.D., wall, or both.
A cold forming process, commonly used in tube and pipe diameter reduction, in which a tube is drawn through a carbide die. The diameter of the emerging tube or pipe reflects the size of the die.
The process of reducing the cross sectional area of wire, bar or tube by drawing the material through a die without any pre-heating. Cold drawing is used for the production of bright steel bar in round square, hexagonal and flat section. The process changes the mechanical properties of the steel and the finished product is accurate to size, free from scale with a bright surface finish.
Cold drawing is a process, for example used in cable core production. Starting from a 1 cm (0.4 inch) thick Cu wire, slowly this is drawn more and more, and eventually small thin wires of 1 micrometer in diameter can be obtained.
