Then we would harden it after machining? Login to see your most recently viewed materials here. 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. Register a523 while it’s still free!

Also, if distortion is a concern, provide some supports.

I foresee problems with distortion and perhaps even cracking of the finish machined parts. The castings already are distorted enough to require dimensional compromises. Join your peers on the Internet’s largest technical engineering professional community.

Hi arunmrao, attached is an image of the part in question, already cast and HRC ish, and needing machining of several features. A little less than 1 inch in thickness 24 mm A 1. And we should try to confirm the actual material. About 2 feet mm diameter.

The following conditions for casting will be supplied: A machine shop has reported that some castings we sent for machining are harder than our drawing specifies. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.

The longer, more complicated part calls for the part to be a5332 to HB. This abstract is a brief summary of the referenced standard. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Abrasion resistant cast irons to ASTM A Standard

Defense manufacturing is all about project manufacturing and project accounting. We are having an ast machining the parts. 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? Please read our License Agreement regarding materials data and our Privacy Policy. Combining values from the two systems may result in non-conformance with the standard.

About 4 feet mm long. Heat treatment shall be s532.

My question is, can high chrome cast iron be “heat treated” to re-harden to HB after annealing or even tempering to ? Hi arunmrao, The shop has replied says they are using cubic boron nitride tooling.

Four 16 mm holes drilled in the body about 12 inches mm from the large end with no flange. 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 a52.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. We have approached the foundry to answer questions about softening and heat treating options.

There is no issue involved. Download Now Defense manufacturing is a5532 about project manufacturing and project accounting. We anticipated HB, which is 51 to 52 Rockwell C. We were casting our own and kept retained austenite very low. Historical Version s – view previous versions of standard. Re-hardening is not advised as parts break easily.
