Detailed Product Description: | 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 SKD11 suppliers 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, reducing the tendency to overheat the steel, thereby reducing the tendency to quench cracking. Processing and heat treatment of high alloy tool steel, low alloy tool steel than is usually more difficult, so the mold manufacturing costs are higher, while the ASP-23 high speed steel powder its machinability, manufacture than traditional methods of high-alloy tool steel Fortunately, dimensional stability, heat treatment is relatively good, and easy to predict. More because of ASP-23 high hardness, good toughness and high temperature tempering characteristics, especially for surface treatment, very easy to process. Two heating changes when heated to room temperature and tissue transformation of austenite and martensite transformation upon heating tempering; three cooling transformation of austenite to pearlite transformation of austenite to bainite transformation of austenite to martensite transformation. So according to these theories and data can be formulated heat treatment process or the operation system. Of course, some practical experience and operational capacity is a must. Recent domestic policies to stimulate the market demand for the introduction of intensive Treasury canceled coal import tariff on the market sentiment to form a strong boost. APEC summit to be held in Beijing, environmental management efforts to increase steel production is expected to bring, but also the formation of the steel market confidence boost. Recently black chain futures eye-catching performance, iron ore futures limit SKD11 manufacturers, threaded futures also just under 1 yuan limit SKD11, spot businesses will significantly push up the market mainstream offer short term cumulative increase of nearly hundred dollars. However, the price level after a turnover and no timely follow-up SKD11 sheet, lower procurement initiative slowdown, the business mentality tends to be cautious, resources to pull up too fast quote section loose. Given the current stocks are low, specifications shortage and other factors on the current market price is still strong support, short-term price or low balance finishing.
