Discussion Overview

The discussion revolves around the term 'as-cast' in the context of cast products, exploring its definition and implications regarding processing, machining, and heat treatment. Participants share their understanding and experiences related to the term's usage in various applications.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants propose that 'as-cast' refers to the part directly out of the casting process without any additional machining operations.
  • Others argue that 'as-cast' typically indicates that the part has not undergone heat treatment, although this is not universally agreed upon.
  • Several participants note that 'as-cast' parts may be delivered directly if tolerances are sufficiently loose, implying that further processing is not always necessary.
  • There is a consensus among some that 'as-cast' means the absence of mechanical processing such as machining, grinding, or polishing.
  • A few participants express uncertainty about the term's relation to heat treatment, suggesting that it may apply in specific contexts.

Areas of Agreement / Disagreement

Participants generally agree that 'as-cast' refers to products that have not undergone further processing, but there is disagreement regarding its implications for heat treatment and the extent of machining that may or may not be involved.

Contextual Notes

Some limitations include varying interpretations of the term 'as-cast' based on specific industry practices and the potential for differing definitions depending on context.

I keep coming across this term. Is it just referring to the alloy after it has gone through the casting process?
 
Engineering news on Phys.org
It just refers to the part as it is directly out of it's cast. No extra machining operations were done. I don't think it is normally used for the purpose of describing heat treat, but I could be wrong.

There are lots of situations where a part needs certain machining operations done to it after casting to bring it within tolerance or surface finish. However, if the part's tolerances are sufficiently loose, an "as cast" part may be delivered directly.
 
I am pretty sure its without heat treatment.
 
That part, or feature has been cast but not undergone machining, grinding, linishing, polishing, sanding...

I've never heard it used in relation to heat treatment (or a lack thereof) but I guess if you're working in the heat treatment field it would apply.

i came across this term a few times where it meant that the material was not heat treated.
 
In my experience, 'as-cast' refers to a cast product without further processing, i.e. no mechanical and/or heat treatment.

I've seen surface finish requirements on cast products where the surface is referring to 'as-cast', i.e., no machining, grinding, linishing, polishing, sanding... as brewnog mentioned.

Mine too...
