Cast irons like steels are basically alloys of iron and carbon. Cast irons contain between 2 and percent carbon. Since the high carbon content tends to make cast irons very brittle, most commercially manufactured types are in the range of to percent carbon.
The cast white iron conforms to ASTM A532 Class II Type B. White Iron is very brittle, exhibiting very little ductility, so tensile and impact tests are not usually a part of the ASTM specification for white iron. This material is normally specified to a hardness criterion. It responds to .
Heat Treating of Gray Irons: Part One. The flake graphite in gray irons is dispersed in a matrix with a microstructure that is determined by composition and heat treatment. The usual microstructure of gray iron is a matrix of pearlite with the graphite flakes dispersed throughout. In terms of composition, gray irons usually contain to 4% C,...
Improvement of abrasive wear resistance of the high chromium cast iron ASTM A532 through thermal treatment cycles tablE I ChemiCal Composition of high Chromium Cast iron Element C Cr Si Mn Mo wt. % According to the obtained values of the main alloying elements (C, Cr), it is assumed that the material meets
by alloying and heat treatment. The various grades of regular, unalloyed ductile iron are designated by their tensile properties (Table 3). Heat treatment of ductile cast iron includes stress relief and annealing, as well as heat treatments used for steels including normalize and temper (for higher strength and wearresistance), quench and temper
RE: annealing and rehardening ASTM A53293 Class III Type A high chrome abrasion resistant cast iron. attached is an image of the part in question, already cast and HRC 60ish, and needing machining of several features. About 4 feet ( 1200 mm ) long. About 2 feet ( 600 mm) diameter. A inch thick ( 25 mm) thick flange on one end.
ASTM A532 Class II Type B High Chromium Alloy The 15%Cr alloy is typically poured on request at Penticton Foundry. With the lower Cr and an addition of Molybdenum, this alloy is used in operating environments where abrasion and impact are the wear mechanisms.. With specific heat treatments it is possible to achieve a high hardness for abrasion resistance, and with a lower carbide ratio the ...

Abrasion Resistant Cast Iron Abrasion resistant cast irons are used in high wear applications where strength is required. Many alloy additions are made to deliver a range of properties and the application of the various heattreat processes can also deliver different performance characteristics of these grades.
• Malleable Iron is a cast metal produced as white cast iron and heat treated to convert the carboncontaining phase from Fe 3 C to a nodular form of graphite called temper carbon. Malleable Iron • There are two types of ferritic malleable iron: blackheart and whiteheart. Only the blackheart type is produced in the United States.
Abrasion resistant cast iron is used in wear applications where strength is required.
Cast iron heat treatment. We need to properly select optimal chemical composition to obtain a given organization for cast iron production,heat treatment is also an important way to further adjust and improve matrix structure in order to improve the iron heat treatment has some way with cast steel heat treatment,but also exist iron heat treatment generally ...

The variations of microstructure and mechanical properties of a highchromium cast iron for rolls were studied from ascast to the final heat treatments. Results show that the ascast microstructure of the HCCI consists of M7C3 carbide, M23C6 carbide, martensite matrix, and retained austenite.
in a standard tensile test. Malleable iron is cast as white iron, then "malleabilized" (, heat treated to impart ductility to an otherwise brittle material). Besides the four basic types, there are other specific forms of cast iron to which special names have been applied.
formed in the solid state during heat treatment. The iron is cast as a white iron of a suitable chemical composition to respond to the malleabilizing heat treatment. Alloyed iron—This classification includes gray irons, ductile irons and white irons that have more than 3% alloying elements (nickel, chromium, molybdenum, silicon or copper).
Malleable cast irons are formed via a slow annealing heat treatment of white cast iron. This results in the conversion of carbon, in the form of iron carbide in white iron, to graphite, with the remaining matrix being composed of ferrite or pearlite [1].

Blue Light Industry > Foundry Heat Treatment > Materials Specifications. The foundry is capable of single piece casting of cast iron up to 7 tons, steel up to 4 tons and nonferrous up to tons. Types of materials cast include: Plain carbon steels. High tensile alloy .
DuraBar G2 is a pearlitic gray iron containing Type A graphite. Gray Iron bars made to this specification have optimal strength, wear and hardness when compared to the other gray iron grades. This material is well suited for applications requiring high resistance to wear and response to heat treatment.
