Chemical treatment include carburizing, nitriding, boronizing, multicomponent permeation and so on. Processing methods can be divided according to the gas law, solid law, bath method. Selection of different penetration enhancers and process parameters on the formation of gas carburizing, solid carburizing and salt bath carburizing. Gas method the workpiece is heated in an oven, into the reaction gas at a high temperature activating gas atoms into the workpiece surface. Gas method is relatively simple, but the processing time is generally longer. Solid method is powdered solid penetration and the workpiece is buried in the box, placed in an oven heated, the advantage is simple, the drawback is the quality of the diffusion layer is not stable enough, when a large box of air pollution. Salt bath method is heated to melt the solid state penetration, the workpiece is placed inside the heating bath, good quality general diffusion layer for Boronizing. Permeation and salt bath salt bath nitriding reaction of cyanide salts or required in the use of cyanide occurs, which all belong to virulent, should be carefully selected. Meanwhile alloy content increases, but also strengthen the austenite, it is difficult to stress relaxation by plastic deformation, thereby increasing heat stress, increased quench cracking tendencies. However, increased content of alloying elements to improve the steel hardenability, quenching medium available gentler and quenching can reduce quench cracking tendencies. In addition, some alloying elements such as vanadium, niobium, titanium, which are austenite grain refinement effect and reduce the tendency to overheat SKD11 steel prices, thereby reducing the tendency to quench cracking. Determines the shape of the mold shape of these products, processing quality and precision mold will determine the quality of these products. The future of China's mold industry after the restructuring, will be increasingly high precision molds, mold steel requirements are also increasing. High-speed steel quality even without segregation, wear resistance, high toughness, to meet the requirements of the service life of the mold manufacturing. Different furnace, power is not the same. Not the same as the heating medium heating capacity is not the same, of course, will be different heating rate, in general, the heating effect due to thermal conduction in a salt bath furnace, box furnace faster than SKD11 rod, while the lead bath heating rate faster than salt bath furnaces. In the sheet market SKD11, prices overall fell. Hot rolled coil prices relatively small decline, Shanghai, Hefei, t price fell 20-50 yuan week. Shanghai market is hot-rolled prices rose and then fell, the market traded poor business mentality turned pessimistic, increasing the prices of space. Plate dropping the overall market is vulnerable, Shanghai, Jinan and other places t price one week fell 20-80 yuan. Shanghai market SKD11 material, demand gradually weaker, and in turn replenish the resources of new goods into the market, the supply pressure is diminished. Businesses can only wait and see.
