Difference Between Hot and Cold Rolled Steel Metal Sep 11, 2014 · Hot Rolled Steel Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steels recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. HIGH QUALITY HOT ROLLED STEEL REBARBS STANDARD Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade

After heat treatment, the tensile strength, plasticity, yield strength and toughness of steel will be improved. In addition, heat treatment can eliminate residual stress.
Hot Rolled vs. Cold Rolled Steel Capital Steel & WireHot rolled steel is rolled or shaped at a high temperature while cold rolled steel is rolled at room temperature. Cold rolled has a smooth and shiny finish while hot rolled has a grey and scaly finish. Cold rolled has sharper corners and more precise dimensions than hot rolled. In general, cold rolled has better mechanical properties than hot rolled. Cold rolled is more expensive than hot rolled.
Mar 14, 2002 · In its natural state, steel is not at all flat. In fact, a hot-rolled sheet coil generally reveals some or all symptoms of poor flatness (see Figure 1 ). For example, 72-inch-wide material with a 100,000-PSI yield strength can have a crossbow of 2 to 12 in., wavy edges, and excessive crown.
