Machining and Heat Treating ASTM A-532. Jul 19, 2011· Does anyone have any experience working with ASTM A-532 25% high chrome iron? These are cast parts.
To summarize, heat treatment D (H.T.D) that applies destabilization after subcritical heat treatment attains an increase in the hardness of the white iron and possibly an increase in the wear abrasion resistance as compared to the conventional destabilization—subcritical heat treatment (H.T.B). This is a result of the different microstructures obtained. The effect of the heat treatments on ...

Microstructural Modifications of As-Cast High-Chromium White Iron by Heat Treatment Article in Journal of Materials Engineering and Performance 18(2):174-181 · March 2009 with 2,218 Reads
silicon (usually 1-3%). The high carbon and silicon content means that they are easily melted, have good fluidity in the liq-uid state and have excellent pouring prop- erties. The basic types of cast iron are best differentiated by their microstructure as opposed to their chemical analysis because the various types overlap (Table 2). The metallurgy of cast iron is more com-plex than its ...
Effect of Alloying Elements on Heat Treatment Behavior of Hypoeutectic High Chromium Cast Iron ... high chromium cast iron, alloying element, heat treatment, hardness, volume fraction of retained austenite 1. Introduction High chromium cast irons, which contain 12 to 30mass%Cr and 1.8 to 3.6mass%C are well known as abrasion wear resistant materials. It is said that their microstructures ...
Our abrasion resistant cast irons can be supplied in a variety of compositions and hardness. Depending on your needs, Penticton Foundry can cast to finished size and/or fully machine your component. If you're wondering why chrome white iron (ASTM A532) is so abrasion resistant,
cast iron under continuous cooling condition was recommended. For broader application, some supplements For broader application, some supplements were made to the formula.
Wear and Abrasion Resistant Cast Irons (White Irons) Click here for the Metallurgy of Cast Iron. White cast irons are widely used in abrasive wear applications involved in the crushing, grinding, milling and handling of abrasive materials such as minerals and ores, both dry and as slurries.

The invention discloses a high-chrome wear-resistant cast iron material and a heat treatment method. The high-chrome wear-resistant 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 ...
The influence of heat treatment on microstructure and mechanical properties of high chromium white cast iron alloyed with titanium was investigated. The austenitizing temperatures of 980°C and 1150°C for 1 hour each followed by tempering at 260°C for 2 hours have been performed and the effect of these treatments on wear resistance ...
Effect of heat treatment on microstructure and mechanical properties ... Jul 25, 2008 ... hypereutectic high chromium white cast iron was investigated.
High chromium white cast irons are multi component alloys that contain iron, carbon and chromium as major elements, and molybdemium, nickel, silicon and manganese either as alloying element or impurities introduced during the foundry process [3-4].
The high level of chromium in high chrome white iron prevents the formation of graphite in the microstructure. Instead of graphite, the carbon in the metal becomes tied up in carbides. These relatively discontinuous chromium-rich, eutectic carbides exist with martensite to make up the microstructure. By controlling the chemistry of the metal and the heat treatment of the castings, toughness ...
