What is difference between HR and CR coil?
As indicated above, the main difference between hot rolled steel and cold rolled steel is the temperature at which they are processed. Hot rolled steel is rolled above the material's recrystallization temperature, whereas cold rolled steel is rolled below the material's recrystallization temperature.
