These alloys may be made by melting process and shall have microstructures that consist of carbides, martensite, bainite, austenite, and in exceptional cases, minor amounts of graphite or pearlite. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. Click here to view all the property values for this datasheet as they were originally entered into MatWeb.

If distortion is a possibility and it sounds like it is then re-hardening is going to be mighty risky, so I’d much prefer machining to be the last step.

Some of the curves in the “Abrasion Resistant Cast Iron Handbook” suggest some high chrome irons can end up with vastly different hardnesses even after tempering to the same temperature, depending aetm retained austenite.

This specification deals with abrasion-resistant cast irons used for mining, milling, earth-handling, and manufacturing industries. For The shorter, simpler part we called for an as cast hardness of HB.
