Cold rolled sheet or plate is put into a furnace and heated to a temperature below the melting point of the material. The steel is removed from the furnace and allowed to cool to room temperature. When heated, the steel grain realigns and some of the effects of work hardening are diminished.
A36 Hot Rolled Steel Plates, Hot Rolled Steel, Hot Rolled
A36 Hot Rolled Steel Plates. FEATURESExcellent for Welding, Drilling, Machining, Shearing and Forming. USESBase Plates, Gussets, Liners, Etc. The process to create Hot Rolled Steel creates a more ductile steel with a rough surface finish and is sometimes more difficult to machine.
Steel, Commercial Forms Hot and Cold Roll steel, shapes
Today however this steel is often A36 structural grade that is cold rolled immediately from the hot roll after spray quenching to remove the scale. The quality of the steel is not as good, finish is not as good, and the temper is usually harder than cold drawn. Sheared and rolled from plate starts as HR plate that has been rolled to its final thickness dimension at a black heat. This leaves a fine finish and a hard temper.
Cold reduction creates a thinner product, one with a thickness that cannot generally be obtained in hot rolled steel. In addition to being made thinner, cold reducing makes the steel harder and less ductile. The cold-reduced steel is then annealed (heated to high temperatures) to make it soft and formable.
Nov 14, 2017 · A36 is a low carbon steel. Low carbon steels are classified by having less than 0.3% carbon by weight. This allows A36 steel to be easily machined, welded, and formed, making it extremely useful as a general-purpose steel. The low carbon also prevents heat treatment from having much of an effect on A36 steel. A36 steel usually has small amounts

steel-cold rolled Cold rolling increases the strength and hardness and decreases ductility of steel by rolling it at ambient temperature (or below its recrystallization temperature). In addition to improvement of mechanical properties, the cold rolling produces steel plate/sheet of the desired physical dimensions.
Materials 101Hot Rolled Steel vs. Cold Rolled Steel
Hot rolled steel actually reconfigures itself during the cooling process, giving the finished product looser tolerances than the original material and when compared to cold rolled steel products. Hot rolled steel is more malleable, allowing it to be forced into a variety of different shapes.
Apr 24, 2017 · The steel is then allowed to cool slowly to room temperature in still air. This annealing process recrystallizes the steel for greater ductility, but because the steel is worked at room temperature, it maintains its strength. Working cold-rolled steel is much more difficult than working hot-rolled steel, so only basic shapes are possible.
