Detailed Product Description: | Mold just include Die, drawing dies, drawing die, pressure die, thread rolling dies, rolling plate, cold heading and cold extrusion die molds. There are steel cold mold, according to its manufacturer with working conditions, should have a high hardness, strength, wear resistance, adequate toughness, and a high rate of penetration, rate of rigid and other process performance. Mold just include Die, drawing dies, drawing die, pressure die, thread rolling dies, rolling plate, cold heading and cold extrusion die molds. There are steel cold mold, according to its manufacturer with working conditions, should have a high hardness, strength, wear resistance, adequate toughness, and a high rate of penetration, rate of rigid and other process performance. As a result of improper processing of steel castings, or surface may be formed within the pores, loose, trachoma, segregation, cracks and other defects in the process of thermal processing technology; in forging blank, it is possible to form a shrinkage, segregation, white point, inclusion material, such as cracks. These defects have a great influence on the quenching cracks steel. In general, the more severe the original defect, the greater the tendency of its quenching cracks. Factors affecting the thermal fatigue resistance of steel are mainly: ① steel thermal conductivity. High thermal conductivity die steel, can make the mold surface to reduce metal degree heat, thereby reducing the tendency of the thermal fatigue of steel. Generally believed that thermal conductivity and cooperation related to the amount of carbon steel, tool steel wholesaler low thermal conductivity at high carbon content, it should not be hot work die steel with high carbon steel. Commonly used in the production of carbon steel (C0.3% 5 ~ 0.6%) combined carbon content is too low. Causes the decrease in the hardness and strength of steel. Is disadvantageous. Critical point ② Steel. The critical point is usually steel (Acl) is higher. The lower steel thermal fatigue bias. Steel mold steel very tough in the work process, the mold bear the brunt of the load, in order to reduce the use of the process of breaking, chipping and other forms of damage, mold steel requires a certain degree of toughness. Number of factors mold steel chemical composition, grain size, purity, carbides and inclusions, morphology, size and distribution, as well as the microstructure and other heat after heat treatment systems and obtained all die steel-on-steel a great deal of impact toughness. Yong Wei mold steel, tool steel quality, Shantou mold steel supplied by AsiaVest steel mold.
