Cold working die steel in the work. Because of the deformation resistance of the material is relatively large, the work of the mold is very cold to die steelCold working die steelGreat pressure, bending force, impact force and friction force. As a result, the normal scrap of cold working dies is generally wear and tear.Compared to cold die steel and tool steel. There are many things in common. Requirements of the mold with high hardness and wear resistance, high flexural strength and toughness enough, in order to ensure the smooth progress of the stamping process, the difference is that the shape of the mold and process complex. And the large area of friction. Wear high probability. Therefore, the grinding difficult. Therefore it requires a higher wear of the die working under impact pressure. Also, due to the complex shape is easy to produce stress concentration, so the requirement with high toughness; die size of a large, complex shape. Therefore require the hardenability of the high permeability and less deformation and cracking tendency. In short, the cold as die steel in quenching through resistance, abrasion resistance and toughness requirements to be higher than the steel cutting tools. And in terms of red hardness is required low or no requirements (because it is cold forming), so it is corresponding to the formation of the some suitable cold working die steel, for example, the development of high wear resistance, micro deformation of cold working die steel and high toughness cold working die steel etc.. The combination of steel used on the further explanation.Cr12Performance: high carbon, high chromium type of Lai steel, with good quenching and good abrasion resistance. Due to the steel in carbon mass fraction up to a maximum of $2.30%. Thus, the steel becomes hard and brittle, so the impact toughness is low, almost can not bear large impact load, easy to brittle fracture, but also easy to form a eutectic carbide is not uniform.Uses: used in the manufacture of under impact load is less and high wear resistance of cold die and punch, shear hard and thin metal cold cutting edge, drilling sleeve, gauge, wire drawing die, stamping die, rub silk board, drawing die and screw rolling die and so on.The production of varieties: hot rolled, cold drawn material, forging, hot rolled steel, cold drawn steel wire.Cr12Mo1V1Performance: high carbon, high chromium type of Lai steel, no special requirements when the drill does not need to add elements. Because the content of molybdenum and vanadium is higher than that of Cr12, the microstructure and grain size of the steel is further refined, so that the steel is quenched, strength and toughness.Usage: it is used for manufacturing requirements with high abrasion resistance for large complicated cold die, such as cold cutting scissors, cut side mode, drawing die, rub plate wire, thread rolling die, binding mode and requirements of high wear resistance of the cold of the die and the punch etc..The production of varieties: hot rolled, cold drawn material, forging, hot rolled steel, cold drawn steel wire.Cr12MoVPerformance: high carbon, high chromium type of Lai steel, with a good quenching, cross section size in the 400mm can be completely quenched, and has a very high wear resistance, small changes in the size of the quenching. The carbon content of steel is lower than that of Cr12 steel, and the addition of molybdenum and vanadium, therefore, the thermal processing performance, impact toughness and carbide distribution have been significantly improved.Uses: used in the manufacture of large cross section, complex shape, wear resistance requirement is high and bears larger impact load of cold working die, such as cold cutting scissors, cut side mode, binding mode, gauge, wire drawing die, rub plate wire, thread rolling die, complex shape punch, plate deep drawing die, and requirements high wear resistance of the cold of the die and the punch etc..The production of varieties: hot rolled, cold drawn material, forging, hot rolled steel, cold drawn steel wire. Die steelDie steelCr5Mo1VProperties: high alloy content of medium, because of containing molybdenum and vanadium, so the steel has good quenching, carbide distribution, has a certain impact toughness and good wear resistance.Use: for the manufacture of mold, die, punch, drill sleeve, trimming die, thread rolling die, screw plate and gauge etc..The production of varieties: hot rolled, cold drawn material, forging, hot rolled steel, cold drawn steel wire.9Mn2VPerformance: comprehensive mechanical properties than carbon tool steel good, with a high degree of hardness and wear resistance, quenching is very good, the deformation is small. Because of a certain amount of vanadium in the steel, the grain size is refined, and the thermal sensitivity is reduced. Carbide inhomogeneity is better than CrWMn steel.Uses: used in the manufacture of various precision measuring tools, templates, as well as the general requirements of the small size of the die, cold pressing die, die carving, feed mode, scissors, tap, die and the reamer.The production of varieties: hot rolled, cold drawn material, forging, hot rolled steel, cold drawn steel wire.According to the requirements and specifications of the supply module.CrWMnPerformance: with a high degree of quenching, due to the addition of 1.20%%26mdash; 1.60% (mass fraction) of tungsten, the formation of carbides, so in the quenching and low temperature tempering with a certain degree of hardness and wear resistance. Tungsten helps to maintain a fine grain, so that the steel has good toughness, the steel mesh carbon material to form a more sensitive, and the carbon property network the tool edge spalling risk.Purpose: use a relatively wide range of cold working die steel. Used in the manufacture of tools, such as die, gauge, column and sample sets, and the complex shape, high precision die etc..The production of varieties: hot rolled, forged material, cold drawn material, cold drawn steel wire, steel wire clamp, hot rolled steel plate, cold rolled steel plate.9CrWMnPerformance: low alloy cold working die steel, with a certain degree of quenching and wear resistance, quenching deformation is small, the carbide distribution is uniform and fine particles.Use: for the manufacture of small section, and more complex shape of the die, and the gauge, measuring model etc..The production of varieties: hot rolled, forged material, cold drawn material, cold drawn steel wire, cold rolled steel plate.Cr4W2MoVPerformance: new and medium alloy cold working die steel, the performance is more stable, compared with the high alloy cold working die steel Crl2, Crl2MoV, with the service life of the mold made of it is obviously improved. Eutectic carbide particles of the steel are small, distributed evenly, with a high degree of quenching and hardening, as well as better wear resistance and dimensional stability.

Therefore, it has high hardness and high strength of high speed tool steel. And because the steel has no excess of carbides, so it has a high toughness and fatigue strength. The steel contains 0.20%%26mdash, 0.35% (mass fraction) of niobium, and the grain size is refined, and improve the temperature of the grain refinement, thus to improve the toughness of the steel and improve the process performance.Use: for the manufacture of cold extrusion dies, cold forging die, screw die, punch, die and screw plate etc..Production varieties: hot rolling, forging.According to the demand supply part or other flat steel bar.6W6Mo5Cr4VPerformance: low carbon steel high speed tool steel types of cold working die steel, its good hardenability and has similar high-speed tool steel of high hardness, high wear resistance, high strength, such as comprehensive performance, compared with a high speed tool steel has good toughness characteristics. The cold extrusion die with this steel is longer. Because of the high molybdenum content in the steel, the hot working temperature range is narrow and the deformation resistance is relatively large.
