Hot Rolled Sheet Steel is an unprocessed, mill edge coiled product and does not include any processing such as temper rolling, tension leveling, pickling, oiling or side trimming. Hot Rolled products are produced to ASTM Specifications A1011, A659, A635 or A1018.
Jul 16, 2014· Cold rolled is the next step along the line of flat-rolled steel products. The process starts with hot rolled P&O. Hot rolled is processed to a final thickness that is heavier than most sheet products. A cold-reducing process is used, which results in a thinner thickness. The cold reduction starts with tension to the sheet.
Steel Forming Process 2 – Cold Rolled Steel. Cold rolling is a metal working process in which metal is deformed by passing it through rollers at a temperature below its recrystallization temperature. Cold rolling increases the yield strength and hardness of a metal .
Cold Rolled steel has an improved surface finish and tighter tolerances compared to hot rolled steel. It is commonly used for parts requiring cold forming, such as crimping, swaging or bending. It can also be used for Shafts, machinery parts, bolts, pinions, gears, as well as in the creation of furniture, appliances and other consumer goods. ...
Hot Rolled Steel vs. Cold Rolled Steel. The difference between hot rolled and cold rolled steel is this recrystallization point. Cold rolling is done when the metal is able to form "new grains" as the old ones are deformed by rolling and bending the metal.

Dimensionally, the differences between a hot mill product and a cold rolled product are as follows: The outside corners of a hot mill product will usually be square corners, whereas the cold roll formed product will have radius corners which are a product of the inside radius (usually 1T or greater) plus material thickness and stretch.
We're often asked about the differences between hot rolled steel and cold rolled steel. Here's what you need to know! All of ours UB, UC, PFC, RSA, flats are hot rolled whereas SHS, CHS, RHS that we provide are cold rolled structural steel.
Sep 11, 2014· Customers often ask us about the differences between hot rolled steel and cold rolled steel.There are some fundamental differences between these two types of metal.The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade.
Nov 22, 2016· The first cold-formed I heard about was a mill designed and owned by Krupp Steel. This mill was sold in the late 70s to the Canadian company Casteel and moved from Germany to Canada and later to the United States. The first cold-formed steel sheet pile sold in America was in the mid 70s by an agent for Krupp Steel.
Cold rolling cannot reduce the thickness of a workpiece as much as hot rolling in a single pass. Cold-rolled sheets and strips come in various conditions: full-hard, half-hard, quarter-hard, and skin-rolled. Full-hard rolling reduces the thickness by 50%, while the others involve less of a reduction.
One important difference to understand is hot rolled steel and cold rolled steel. This lack of knowledge concerning the two types of steel is more common than you would think. The difference is not in their specifications or grade, but in how they are processed at a mill.
