2014年9月11日 · Hot rolled steel involves rolling the steel at high temperatures, whereas cold rolled steel is processed further in cold reduction mills where the material is cooled, followed by annealing and/or tempers rolling.

Mild Steel Hot Rolled pipes provide a uniform surface and structural integrity, while offering excellent load-bearing capacity and ease of fabrication. Hot rolled steel is formed through a metal rolling process where the steel is pressed at temperatures above the its recrystallization threshold.

What is the Difference Between Hot Rolled (HR) & Cold Rolled (CR) Steel? The main difference between hot and cold rolled steel is in how they are processed. Hot rolled steel is steel that has been rolled at high temperatures, while cold rolled steel is essentially hot rolled steel that is further processed in cold reduction materials.
