Hot Rolled

Overview

Hot rolled products are produce from the deformation of plates at high temperatures in a hot strip rolling mill. Through the combination of the chemical composition variables the hot rolling thermomechanical process parameters is possible to achieve a wide range of standards and specifications for several market segments and specific uses.

These products are delivered to the market as coils or plates, and are divided by thickness as follows:

  • HC (Hot Coil) - coil with a thickness of 1.45 to 5.00mm;
  • HTS (Hot Thin Sheet)- plate with a thickness of 1.45 to 5.00mm;
  • TC (Thick Coil) - coil with thickness of 5.01 to 12.70mm;
  • TS (Thick Sheet) - plate with a thickness of 5.01 to 12.70mm;
  • HPC (Hot Pickled Coil) - pickled and oiled coil with a thickness of 1.50 to 4.75 mm.

Note: Materials commercialized as hot rolled products typically exhibit an iron oxide layer on the surfaces that was naturally formed during the process.

(1)The chemical composition and the mechanical properties of the grade A are from PSL-1 grade (PSL-2: not contained);

(2)The values presented correspond to the PSL-2 grade. The mechanical properties considered for PSL-1 will be equal to the minimum values from PSL-2 grade.

(3)The minimum elongation in 50/80 mm base shall be determined by the formula as follows:

Elongmín = 1942.57 x A0.2 / U0.9 - metric formula
A = cross section area (mm²)
U = minimum ultimate tensile strenght (MPa)
