COLOUR MATERIAL TYPE RELATED STANDARDS NOMINAL COMPOSITION TYPICAL MICROSTRUCTURE

27%Cr White Cast Iron AS 2027 Grade Cr27 ISO 21988 Grade Cr27 ASTM A532 Grade IIIA Composition is confidential The microstructure of Alloy A05 consists of eutectic M7C3 and secondary carbides in a ferrous matrix predominantly of martensite. A small amount of retained austenite may be present in the final microstructure. A05 is heat treated to develop high hardness and optimum erosion resistance. Alloy A05 is a wear resistant white cast iron that offers excellent performance under erosive conditions. The alloy can be effectively used in a wide range of slurry types. The high wear resistance of alloy A0 5 is provided by the presence of hard carbides in the microstructure. Alloy A05 is particularly suited to mild acidic duties where erosion resistance is required.

GENERAL DESCRIPTION PARTS AVAILABILITY SERVICE RECOMMENDATIONS SPECIAL NOTES

Most wet-end parts can be manufactured in alloy A05. The most common parts are as follows: Impellers, volute liners, throatbushes, frame plate liner inserts, bowls and doors. Alloy A05 can be used for pumping a wide range of mildly acidic duties. The alloy gives excellent wear life for a variety of particle size and hardness. Manufactured in Australia, UK, USA, Chile, Brasil, South Africa and Malaysia. Ultrachrome is a registered trademark of Weir Minerals Australia Ltd. Golden Yellow

Alloy A05 is generally not suitable for highly corrosive duties. The a lloy c an be used in mildly acidic duties, within a pH range of 5 to 14 for sulphuric and nitric acids, or sodium hydroxide applications. Refer to Figure 4. The corrosion diagrams were plotted using data obtained in laboratory tests in reagent grade a cids a nd so dium chloride. This da ta should be used only as a guide. It is recommended that samples be tested under actual plant conditions.
