Heat Treatment Technology of High Chromium Iron
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 requirements 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 Heat Treatment of Cast Irons Industrial 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

(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 high temperature heat treatment and a rapid quench The extralow carbon content of alloys CF3 and CF3M can be welded without postweld heat treatment because very little chromium carbide can be formed Chromium depletion is avoided in the CF8C alloy type by the intentional addition of columbium carbides instead of chromium carbidesSTEEL CASTINGS HANDBOOK Supplement 7 Welding of 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
