How can identify rolling direction in plate?

[limesh M]

Dear All,

For preparing test pieces for PQR, the following item to be fulfilled as per a document.

"For butt weld test assemblies Identification of the rolling direction of the used plates shall be provided."

My query is that,is it possible to identify the rolling direction by naked eye?If possible what is the trick behind it?



Regards,

Limesh

Limesh,   Normally the direction in which the data is stenciled/printed/painted will be the direction of rolling. Regards, Nandeesh --- On Fri, 8/7/11, limesh M <lime...@gmail.com> wrote:

By little experience you can identify the roller marks (series of closely spaced lines), which indicate the final direction of rolling. This cannot be done if the plate is ground or coated. Should not confuse with corrosion marks like rust.

Dear Mr.Limesh..

 

You cann't identify the rolling direction in offcut plates or cut pieces..

Why not, simple light acid etching and sulfur prints should do the job --- On Fri, 8/7/11, muthusrinivasan muthuselvam <msm...@gmail.com> wrote:

Dear Limesh,

u have only one way to identify the rolling direction by making Macro etching for the surface then u will find out the grains boundaries elongation direction

hi ,
For the rolling direction of the plates i would look at the edges
of the plates mostly the sheared edges and the original untouched
edges could help to identify .
Also i would say that along the length of the plate would be the
rolling direction in majority of the cases...
This would e applicable only for full sized plates...
hope this will help
regards

Hello All,

 

Normally during manufacturing hard stamps and/or markings will be applied perpendicular to the final rolling direction. Cutting of pieces from certified plates for projects where certified material are required is only allowed after re-stamp by a person having a re-stamp declaration of a notified body, or a notified body itself. One of the important things such people should know is that new stamps always should be applied in the same direction as the original ones, so in that case you can always identify your rolling direction.

Hi limesh,

 

Take a sample from one edge of the plate & send it for testing for the direction of grain elongation. Generally the elongation is lesser towards the rolling end.

 

ARAMCO Spec's for HIC testing calls for samples to be taken from the end of the plate where the rolling ends. We generally send the samples to laboratory for the evaluation of the rolling direction.

Dear Coleague,

exist an portablle microscope - x200- with nital atac is possible to identify rolling direction in make-phase
