Fig.UCS-66 (g)(3) Normalized rolling condition

Fig.UCS-66 (g)(3) Normalized rolling condition

Fig.UCS-66 (g)(3) Normalized rolling condition

(OP)
Hi,
ASME Section VIII Div.1 Fig.UCS-66 (g)(3) states that
"Normalized rolling condition is not considered as being equivalent to normalizing"

Does it mean that if heads formed in normalizing temperature, can not be assumed as normalized.

Regards

RE: Fig.UCS-66 (g)(3) Normalized rolling condition

pvesseleng;
Yes, you are correct. Normalizing is a separate heat treatment operation.

RE: Fig.UCS-66 (g)(3) Normalized rolling condition

Agree with metengr.

If you are having heads made see SA-20(6.4).

Think I would get more info. Perhaps the item is formed at normalizing temp. and then held there for a time after forming. Would this be the correct end result?

RE: Fig.UCS-66 (g)(3) Normalized rolling condition

Yes, provided the time at temperature and cooling rate has been documented.

Lets assume the item is formed at normalizing temp. and then held there for a time after forming. Results; time and temperature recorded on material test report.
Is this the same situation explained in ASME Section VIII Div.1 Fig.UCS-66 (g)(3)?
thank you for your valuable comments

RE: Fig.UCS-66 (g)(3) Normalized rolling condition

The normalized rolling condition means that the material is at least heated to some temperature above the lower critical transformation temperature (AC1) for working and cooled in air.

Normalizing heat treatment occurs when the material is heated about 100 deg F above the upper critical (AC3) transformation temperature ( assuring 100% austenitizing treatment) and held for a specific period of time and cooled or liquid quenched, if necessary.

or liquid quenched, if necessary.

The above statement was not part of the thread response above. The thread should have ended with ...and cooled in air.
