What defines "wrought material"?

What defines "wrought material"?

(OP)
What defines "wrought material"?  Can both hot and cold finished material be wrought?  That is, can a cold rolled sheet and a hot rolled bar (not cold worked) both be wrought material?  Does wrought material need to be cold worked/strain hardened?

Thanks.

RE: What defines "wrought material"?

Yes to second and third questions. No to second.

RE: What defines "wrought material"?

Pardon. No to 4th question.  

RE: What defines "wrought material"?

The word "wrought" is the past participle of the 13th century English verb "work". Metals are usually cast during manufacture and can be used in that condition but tend to be brittle, have a coarse microstructure and contain segregation of different constituents. The properties can be markedly improved by working - the grain structure is refined, mechanical properties improved, etc. Usually the cast structure is broken down by hot working which can be followed (but not necessarily required ) by cold working. The material will have been "wrought" by these operations.

RE: What defines "wrought material"?

Does that mean WP are all cast products, further subjected to hot and /cold working. What exactly is hot working? and Cold working? Not forging, I think.
Regards

RE: What defines "wrought material"?

No. WP means welded pipe product form. As TP stands for tubular or pipe product forms. Casr designation is WC - weldable caat grade.

Wrought means material that is subjected to forming - extrusion, rolling, forging, upsetting....


Forming as mentioned above can be done hot or cold.


Hot forming - rolling or forging or extruding, is performed above the recrystallization temperature of the material.


Cold forming - same processes above except performed below the recrystallization temperature of the material.

@Metengr:

This re-hashes a question I had from a previous thread.

If I specify and purchase a:

14" OD x .375"nom thickness SA-403 WP304L cap

WP stands for?

-TJ Orlowski

RE: What defines "wrought material"?

Weldable Pipe product form - WP

RE: What defines "wrought material"?

If you specify a WP304L pipefitting then you can get either a seamless or a welded one but both will have been made from a wrought product (WP). If you want it without a weld then you must add "s" to the designation - so it becomes WPS (similarly WPW for a welded fitting). All fittings in A403 are wrought. Cast fittings are not covered by this secification.
WPS fittings such as elbows and tees are made from wrought seamless pipe which has been hot finished (extruded) or cold finished (rolled) or both.
WPS caps are made from plate which has again been hot rolled or cold rolled or both.
WPW fittings incorporate a weld. With elbows and tees, the weld may come from the start pipe or the fittings can be made from other pieces of pipe or plate suitably formed to the right shape and then welded together.

RE: What defines "wrought material"?

enmax;
Weldable casting grades are designated as WCX. So, does this mean W is wrought? No. As I stated above, W means weldable, not welded, it can be welded.

RE: What defines "wrought material"?

Déjà vu...this debated topic is familiar.

No sale.  There is no weld, and no pipe of any kind present in the part I used as an example.  IF weldable pipe means "can be welded to pipe," that wouldn't make any sense.

Please reference the specification you're referring to regarding WCX castings.

WP is a wrought product.  Across carbons, stainless & alloys, titaniums, and copper & nickel-copper alloys.  WP means wrought product.  TP is a tubular product.

-TJ Orlowski

RE: What defines "wrought material"?

Do you know what weldable means??????????????????????????????
It means it can be welded, it does not mean it is welded.

RE: What defines "wrought material"?

ASME SA 217 Grades WC1, WC4,.....

ASME SA 216 Grades WCA, WCB, WCC

Is that enough evidence to indicate W does not stand for WROUGHT????

RE: What defines "wrought material"?

So you're saying that abbreviations used in spec A must stand for the same thing in spec B?  W means in CAN be welded? and the P means. . . it can be welded to pipe?  or it is a piping product?  Or it is just a product?

Yes, I know what weldable means, but I appreciate your condescension.  If W means weldable, then why doesn't every single piece of weldable material carry WP, or at least W, in the designation?  Regardless of whether it is of welded or seamless construction, if it CAN be welded to something else, it should have a W in the designation, right?  Following your assertion:

SA-312 TP304L should be changed to SA-312 WP304L.  After all, it can be welded, and it is certainly a pipe product form.  SA-105 fittings should be SA-105 WP.  After all, they can be welded, and they can be welded to pipe.  SA-516 Gr.70 should be changed to SA-516 WPGr.70.  After all, it can be welded, and it can be welded to pipe.  SA-240 317 should be SA-240 WP317.  SB-111 C70600 should be changed to SB-111 WPC70600.  After all, it can be welded, and it can be welded to pipe, should a person desire.  I could go on forever.

I'm not going to badger back and forth.  WP means wrought product.  TP means tubular product (not tube or pipe).  I think discerning minds can tell when someone is either grasping at straws or refuses to acknowledge an inaccurate interpretation.

-TJ Orlowski

RE: What defines "wrought material"?

The derivation of "WP" is actually immaterial.  Like the fact that 8" pipe is really 8.625" in diameter, WP, WPB, and the like are just 'shorthand' stamped on the fitting to denote what SA/A spec, grade, and type that they meet.  Don't read so much into it, it is just a shorthand marking now.  What it used to be doesn't really matter, except for 'pipe trivia' that us old guys enjoy playing.
