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. In the heat treatment of steel materials, the practice on the basis of years people have come up a set of simple forms of memory: called a graph, two curves, four fire, five changes. A graph is called iron-carbon alloy equilibrium phase diagram or called iron-carbon alloy state diagrams, organizational change can be summed up many of the common law and the critical parameters of the equilibrium state of the steel material. As more high-grade, high-quality iron ore supply on the market, Chinese steel mills in the low-grade ore negotiations already have more bargaining power. In 57% to 58% grade sinter FMG supply, for example, Chinese steel mills to get the discount for the actual Platts index is the highest compared with 14% discount. January super-special meal discounts had reached $ 4 per dry ton, and now even reached $ 12 per dry ton. Platts recently released data show that the new export orders index in October amounted to 70.96 points, up 12.91 points compared with September, which means that China's steel export volume growth trend will continue in October. In contrast, China's steel sentiment index in October was only 38.09 points, becoming the lowest level in January this year. The data also show SKD11 manufacturers, steel production index in October compared with September fell 6.37 points to 35 points, the fourth consecutive month the index has been below 50 points, reflecting market participants expect steel production will decline. High alloy tool steel machining and heat treatment SKD11, typically less than the low alloy tool steel is more difficult, and therefore mold manufacturing costs are higher, while the ASP-23 high speed steel powder its machinability, manufacture than traditional methods of high-alloy tool Fortunately SKD11 steel material, 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 trading, futures also just under 1 yuan thread limit, the 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 hardness, lower procurement initiative to slow, cautious business mentality, some pull up resources to offer too 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.
