Sheet & plate

HI, Up to what thickness we can say this is sheet and plate ??? and how much its thickness range maximum??

Not sure give a good answer, best ways must refer to the specificied material.
Look at Definitions or Terminology will give your more information.

Example for material specification ASTM A240 - Definitions

  • cold work, n—the changing of mechanical properties by work hardening.
  • plate, n—material 3⁄16 in. [5.00 mm] and over in thickness and over 10 in. [250 mm] in width.
  • sheet, n—material under 3⁄16 in. [5.00 mm] in thickness and 24 in. [600 mm] and over in width.
  • strip, n—cold-rolled material under 3⁄16 in. [5.00 mm] in thickness and under 24 in. [600 mm] in width.

First time I known.

As per ASTM A 6/A 6M:

3.1.1 Plates (other than floor plates or coiled product)—Flat, hot-rolled steel, ordered to thickness or weight and typically width and length, commonly classified as follows:
3.1.1.1 When Ordered to Thickness:
(1) Over 8 in. [200 mm] in width and 0.230 in. or over [over 6 mm] in thickness.
(2) Over 48 in. [1200 mm] in width and 0.180 in. or over [over 4.5 mm] in thickness.
3.1.1.2 When Ordered to Weight [Mass]:
(1) Over 8 in. [200 mm] in width and 9.392 lb/ft2 [47.10 kg/m2] or heavier.
(2) Over 48 in. [1200 mm] in width and 7.350 lb/ft2 [35.32 kg/m2] or heavier.

And it does not give any clear definition for sheet.
