Crucible A2 Data Sheet
CRUCIBLE DATA SHEET Airkool (AISI A2) is an air-hardening medium alloy tool steel ® Issue #1 which is heat treatable to HRC 60-62. It has wear resistance AIRKOOL intermediate between the oil hardening tool steels (O1) and (AISI A2) the high carbon chromium tool steels (D2). Because it offers a combination of good toughness along with moderate Carbon 1.00% wear resistance, it has been widely used for many years in Manganese 0.85% variety of cold work applications which require fairly high abrasion resistance but where the higher carbon/ high Chromium 5.25% chromium steels are prone to chipping and cracking. Molybdenum 1.10% Airkool is quite easily machined in the annealed condition Vanadium 0.25% and, like other air-hardening tool steels, exhibits minimal distortion on hardening, making it an excellent choice for dies of complicated design.

Effect of Heat Treatment (Ferritizing) on Chemical Composition, Microstructure, Physical Properties and Corrosion Behaviour of Spheroidal Ductile Cast Iron
Asian Journal of Chemistry Vol. 19, No. 6 (2007), 4665-4673 Effect of Heat Treatment (Ferritizing) on Chemical Composition, Microstructure, Physical Properties and Corrosion Behaviour of Spheroidal Ductile Cast Iron A.R. ISMAEEL*, S.S. ABDEL REHIM† and A.E. ABDOU‡ Department of Chemistry, Faculty of Science, Garyounis University, Benghazi, Libya E-mail: [email protected] Two steps ferritizing technique was applied on ductile cast iron samples by austenitizing at 900ºC, air cooling to produce pearlite, ferritizing by reheating samples for different times at 700ºC and air cooling to room temperature. Chemical analysis and microstructure showed that as ferritizing time increased, an increase of percentage of ferrite, decrease of pearlite, with corresponding decrease in cementite and increase of free carbon in the form of spheroidal graphite. These changes explain the changes of physical (mechanical) properties repre- sented in the increase of percentage elongation, decrease of tensile strength and decrease in brinle hardness. Weight loss corrosion test technique was followed for investigation of corrosion rate of heat treated samples in 0.1 N H2SO4 solution, which show decrease in corrosion rate with increased ferritizing time. This was explained due to decrease of cathodic sites represented in cementite forming pearlitic lamella. The exception was in the early step of ferritizing, where the corrosion rate increased due to formation of secondary graphite acting as effec- tive cathodic sites. Key Words: Ferritizing, Pearlite, Austenitizing, Microstructure, Cementite, Spheroidal graphite, Cathodic, Corrosion, Secondary graphite. INTRODUCTION Ductile (nodular or spherulitic graphite) cast iron in which a part or all of the carbon is present in the form of a tiny spherical balls, of average 33 to 37 µm1-4.

Heat Treatment of Cast Irons
HEAT TREATMENT OF CAST IRONS Sukomal Ghosh National Metallurgical Laboratory Jamshedpur 831 007 Heat treatment in a general way improves and alters the heat treating objects. The improvements are aimed in respect of mechanical Properties, machinability, homogeneity, relieving of stresses, hardening and others. The application of heat causes certain structural changes in the object responding to subsequent improvements in the properties. CAST IRON - CHARACTERISTICS The ferrous metals, steel or cast irons are essentially an alloy of iron and carbon. The cast iron contains carbon ranging from 2 to 4%, with the element silicon playing a most important role. Silicon influences the eutectic carbon content of Fe - C alloy and with presence of silicon eutectic carbon is estimated as: Eutectic carbon % = 4.25 - 0.30 x (%Si) In cast iron, the carbon is present in two forms. A stable form shows carbon is present as free graphite and an unstable form indicates presence of carbon in a combined form (cementite, Fe3C). Grey cast irons are characterised by the presence of all or most of the carbon in the form of graphite, white cast irons are characterised by the presence of all the carbon in combined form, i.e., in the form of cementite. An iron of borderline composition which freezes partly as a white iron and partly as a grey iron under prevailing conditions of cooling is termed as mottled iron. Two more types of cast irons are also widely accepted as separate class owing to their achieved property. Thus, malleable cast iron derives its name from its ability to bend or undergo permanent deformation before it fractures.

University of Pittsburgh, 2017 One of the most popular elements in weight reduction programs in the automotive industry is high strength zinc coated dual-phase steel produced on continuous hot dipped galvanizing lines. The high strength is needed for mass reduction, while the protective zinc coating is needed to prevent corrosion of the thin gage cold rolled steel. The present study was aimed to explore an optimized way to produce such dual-phase steels with ultra-high tensile strength (UTS > 1280MPa), good global ductility (TE > 18%), excellent local ductility (sheared-edge ductility, HER > 40%) and products of UTS × TE > 22000 MPa × %, conforming to data of AHSS Generation III steel.
