Heat Treatment of Cast Irons Industrial
Common Heat Treatment for the Specific CastIron Types Highalloy (eg, high chromium, high nickelchromium) white irons can be heat treated For example, nickelchromium whiteiron castings are given a stressrelief heat treatment because, properly made, they have an ascast As an antiwear material, High Chrome White Iron Castings have not only necessary strength and toughness, but also their hardness is the most important quality index Some high chromium iron castings can obtain the required hardness in the ascast state, but most of them need heat treatment to meet the hardness requirementsHeat Treatment Technology of High Chromium Iron The invention discloses a highchrome wearresistant cast iron material and a heat treatment method The highchrome wearresistant cast iron material is prepared from iron as a main raw material, and carbon, silicon, manganese, sulphur, phosphorus, chrome, molybdenum, nickel and copper as auxiliary materials in manners of melting and casting after preparationHighchrome wearresistant cast iron material and The invention discloses a highchrome wearresistant cast iron material and a heat treatment method The highchrome wearresistant cast iron material is prepared from iron as a main raw material, and carbon, silicon, manganese, sulphur, phosphorus, chrome, molybdenum, nickel and copper as auxiliary materials in manners of melting and casting after A Highchrome wearresistant cast of its properties at high temperatures, compared to other wear resistant materials [ ] In the ascast condition, the microstructure of high chromium molybdenum white iron consists essentially of dendrites of austenite in a matrix of eutectic mixture of austenite and (Fe, Cr) 7 C 3 carbides [ , ] For many applications, castings are heat Research Article Heat Treatment in High Chromium White

The high controlled percentage of chromium helps to retard the formation of graphite and stabilize the carbides The article of D Kopyciński et al presents results of heat treatment on the high chromium cast iron The study was carrying out on samples cut from the casting made from chromium cast iron transformations on which cast iron heat treatments are based are similar to those applied to steels Heat Treatment of Cast Irons Daniel H Herring, The HERRING GROUP, Inc, Elmhurst, Ill Diamond Platinum Rhenium Palladium Germanium Beryllium Indium Hafnium Silver Cobalt Zirconium Titanium Tin Nickel Magnesium Copper Aluminum Iron 1 10 100 103 Heat Treatment of Cast Irons Heat Treat Doctor on the surface of cast pieces, which adhere very well to the metal Due to this, chrome irons are resistant to the action of heat and various corroding media7 Above 16 per cent Cr, an oxide layer type FcOCr20 , forms on the iron surface, which strongly increases the resistance to heat, making operati ons possible atHighchromium (2234 per cent) Cast Iron Alloys and matrix of the chillcast shell becomes martensitic Special NickelChromium White Iron Alloys Some roll alloys are designed to undergo a modified normalizing heat treatment in order to obtain a bainitic microstructure Microstructure of indefinite chill rollsMetallurgical Aspects of HIGH CHROMIUM WHITE IRONS If the CEV of unalloyed grey iron is low (327337), the ascast strength and hardness is high (case 1 in Table 1510); Normalising (heat at 900°C for 1½ hr, aircool) almost restores these properties; but the unalloyed cast iron with high CEV and low Mn%, not only has low ascast tensile Strength and hardness, but normalising decreases it Heat Treatment of Grey Irons Cast Irons Metallurgy

(usually steel or cast iron) must be heated above the upper critical temperature and then quickly cooled Attention: However, most nonferrous metal castings, like alloys of copper, aluminum, or nickel, and some high alloy steel castings such as austenitic stainless steel investment castings (304, 316), produce an Heat Treatment INVESTMENT CASTING 6 Chrome (Cr) Advantages: a Chrome could improve the hardening capacity of heat treatment, and especially improve the abrasive resistance b In addition, high content of Cr could improve the corrosion resistance, so it is an important alloy for stainless steel Disadvantages: Chrome will reduce the plasticity of cast steel 7 Molybdenum (Mo)The effect of cast steel chemical Iron foundry
