Hardness test shall also be made. We have approached the foundry to answer questions about softening and heat treating options. There is no issue involved.

Abrasion resistant cast irons to ASTM A Standard

What is the part under consideration. This specification deals with abrasion-resistant cast irons used for mining, milling, earth-handling, and manufacturing industries.

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. Or if you don’t have an account with us yet, then click here to register. Are you using cubic boron nitride tips or carbide tips for machining? The Eng-Tips staff will check this out and take appropriate action. You need to check on the current structure, and perhaps do some trials.

Converted from Brinell hardness.

The chemical composition of a class and type that is, Z532 I, Type A shall conform to the range of values specified for carbon, manganese, silicon, nickel, chromium, molybdenum, copper, phosphorus, and sulfur. A little less than 1 inch in thickness 24 mm A 1.

As a first step, I would temper this casting to drop the hardness to BHNbefore attempting annealing. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. I guess we specified the current parts to be as cast HB. If the issue is that they take longer to machine or they adtm through tooling faster, can you throw more money at the machine shop to just work through it?

And we should try to confirm the actual material. The following conditions for casting will be supplied: We were casting our own and kept retained austenite very low.

We are having an issue machining the parts. Worth a shot for a few parts, for a523 parts that approach isn’t going to be realistic.
