Mold steel is used to make Die, forging and molding mold mold steel. The mold is the main processing tools for manufacturing parts in machinery manufacturing, radio instruments, motors, appliances and other industrial sectors. The quality of the mold directly affects the quality of the pressure process, the accuracy of product yield and production costs, quality and service life of the mold in addition to relying on the structural design and machining accuracy, mainly due to the impact of mold materials and heat treatment. Steel mold classification Conditions of service of the United States according to the mold, the mold steel into four categories, listed at the American Society for Metals, Tool Steel Committee: cold work die steel hot work die steel and plastic mold steels, plastic mold steels four major categories. Which, cold work die steel and the separation of the 12 subclasses to 9 subclasses of hot work die steel, plastic mold steel. Liu Die Steel 2 subcategories, plastic mold steel categories. Each subclass of the selection depends on three main factors:◆ the complexity of the size and shape ◆ raw materials ◆ durability requirements or design life. The steel process performance Workability - Thermal processing performance, refers to thermoplastic processing temperature range; hot work die steel. - Cold performance, refers to cutting, grinding, polishing, cold drawing processing performance. Hardenability and Hardenability Hardenability depends on the chemical composition of steel and the original organization of the state before quenching; the hardenability mainly depends on the carbon content in steel. For most of the cold work die steel, hardenability is often one of the main considerations. For hot work die steel and plastic mold steel, the general size of the mold, especially in the manufacture of large mold, its hardenability is more important. In addition, the complex shape prone to heat treatment distortion of various molds, in order to reduce quenching distortion, often as much as possible using less cooling capacity of quenching media, such as air-cooled, cold oil or salt bath cooling, in order to get the required hardness and hardened layer depth, we need to adopt the hardenability good die steel. Quenching temperature and heat treatment distortion In order to facilitate the production, mold steel quenching temperature range as possible to relax some, especially when mold heated by the flame hardening, difficult to accurately measure and control temperature, mold steel quenching temperature range wider. Mold during heat treatment, especially in the quenching process, to produce changes in size, shape warping, distortion, etc., in order to ensure the quality of the mold, require heat treatment of steel mold deformation, in particular, is difficult to trim for the complex shape of precision molds, after quenching more demanding requirements for the degree of heat treatment distortion, it should make use of micro-deformation of the mold steel. Oxidation, decarburization sensitivity Mold in the heating process, oxidation, decarburization, it will make it hardness, wear resistance, the use of performance and service life to reduce; Therefore, the requirements of the mold steel oxidation, decarburization sensitivity. Mold steel with high molybdenum content, due to oxidation, decarburization sensitivity requires the use of special heat treatment, such as a vacuum heat treatment, controlled atmosphere heat treatment, salt bath heat treatment. Other factors In addition to performance and process performance must consider the choice of die steel, but also must consider the versatility of the mold steel and steel prices. Performance requirements 1 Strength properties (1) Hardness Hardness is the main technical indicators of the mold steel mold under high-stress the role of desire to maintain its shape and size unchanged, must have sufficiently high hardness. Cold-working die steel at room temperature, hardness remained at the HRC60 about hot work die steel according to their working conditions, general requirements to keep HRC40 ~ 55 range. For the same steel, within a certain range of hardness values, the hardness and deformation resistance is proportional to; but with the same hardness value, composition and organization of different kinds of steel, plastic deformation resistance may have significant differences.(2) red hardness under high temperature hot die to maintain the stability of its organization and performance requirements, so as to maintain a sufficiently high hardness, this performance is called the red hardness. Carbon tool steel usually can maintain this performance in the 180 ~ 250 ° C temperature range, chromium molybdenum hot work die steel to maintain this performance is generally 550 to 600 ° C temperature range. The red hardness of steel depends on the chemical composition and heat treatment of steel.(3) compressive yield bending strength and compressive strength of the mold during use, often by the strength of high pressure and bending effects, thus requiring the mold material should have a certain compressive strength and flexural strength. In many cases, the compression test and bending test conditions close to the actual working conditions of the mold (for example, measured by the compression of the mold steel yield strength and punch out when the deformation resistance is more consistent) . Another advantage of the bending test is the absolute value of the variable large more sensitive to reflect the different kinds of steel deformation resistance under different heat treatment and organization of the state the difference. 2 toughness in the work process, the mold under impact loading, in order to reduce the break during use, chipping and other forms of damage, mold steel has a certain toughness. The number of mold steel's chemical composition, grain size, purity, carbides and inclusions such as morphology, size and distribution, as well as mold steel, heat treatment and after heat treatment, microstructure and other factors on steel the resilience of a great deal of influence. In particular, the deformation of steel purity and thermal processing for the transverse toughness is more obvious. Toughness, strength and wear resistance of steel are often mutually contradictory.Therefore, reasonable to select the steel chemical composition and the use of reasonable refining, thermal processing and heat treatment process, so that the wear resistance, strength and toughness of mold materials to achieve the best with. Impact toughness Department of table of characteristics of materials to sample the total energy absorbed in the fracture process in a shock process. But a lot of tools in different working conditions of fatigue fracture, conventional impact toughness can not fully reflect the fracture properties of the mold steel. Small energy several attacks on the work of fracture or multiple fracture of life and fatigue life test is being used. 3. Wear resistance Decided to mold the life of the most important factor is often the wear resistance of the mold material. 4 thermal fatigue capacity Hot work die steel under the conditions of service in addition to the cyclical changes of the load bearing, but also by the high temperature and cyclic thermal shock effect, therefore, the evaluation should pay attention to material fracture resistance of hot work die steelthermal mechanical fatigue fracture properties. The thermo-mechanical fatigue is a comprehensive performance indicators, which includes the thermal fatigue properties, mechanical fatigue crack growth rate and fracture toughness of the three aspects. 5. Bite resistance Bite resistance is an actual "cold welding" resistance.
