Sheet or Plate

[Scorch]

I think this is the best place to post this. Let me know if this should go into another forum. I was asked if there was a standard that stated material up to a certain thickness is call "sheet" and anything above that thickness is called "plate". I can not recall if there is a standard for this or not. Is this a company thing?

I think it is a company thing. In college, I heard it said that Caterpillar considered anything up to 3" sheet, while Boeing considered anything over 1/8" plate.

Your thicknesses may vary.

"Fixed in the next release" should replace "Product First" as the PTC slogan.

There are many ASTM standards for steel sheet and plate. ASTM A 635 reflects sheet up to one inch.

The ASM glossary of terms reports the following:

plate
A flat-rolled metal product of some minimum thickness and width arbitrarily dependent on the type of metal. Plate thicknesses commonly range from 6 to 300 mm (0.25 to 12 in.); widths from 200 to 2000 mm (8 to 80 in.).

sheet
A flat-rolled metal product of some maximum thickness and minimum width arbitrarily dependent on the type of metal. It has a width-to-thickness ratio greater than about 50. Generally, such flat products under 6.5 mm (1/4 in.) thick are called sheets, and those 6.5 mm (1/4 in.) thick and over are called plates.
