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

ASTM A532 Grade III-A as cast

You need to check on the current structure, and perhaps do some trials. Combining values from the two systems may result in non-conformance with the standard. Re-hardening is not advised as parts break easily. We are having an issue machining the parts. Converted from Brinell hardness. So now we are waiting to hear from the foundry about how to get the hardness down to machinable levels. MatWeb is intended for personal, non-commercial use.

The chemical composition of a class and type that is, Class I, Type A shall conform to the range of values specified for carbon, manganese, silicon, nickel, chromium, molybdenum, copper, phosphorus, and sulfur. Hardness test shall also be made.

We were casting our own and kept retained austenite very low.

Class III Type E 25% Cr Martensitic White Cast Iron

Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

There is no issue involved. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. And we should try to confirm the actual material. As a first step, I would temper this casting to drop the hardness to BHNbefore attempting annealing.

This abstract is a brief summary of the referenced standard. Red Flag This Post Please let us know here why this post is inappropriate. I have done slurry pump parts and grinding rolls.

A little less than 1 inch in thickness 24 mm A 1. If distortion is a possibility and it x532 like it is then re-hardening is going aastm be mighty risky, so I’d much prefer machining to be the last step. Defense manufacturing is all about project manufacturing and project accounting. We used to stress relief anneal cylinders that we cast, we made sure to stay sub-critical.

Four 16 mm holes drilled in the body about 12 inches mm from the large end with no flange.

Heat treatment shall be done. 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.

If the issue is that they take longer to machine or they go through tooling faster, can you throw more money at the machine shop to just work through it?
