Hot Rolled Steel & Cold Rolled Steel - Difference &

The rolls induce plastic deformation. Thus, the yield strength of cold rolled steel is higher than that of hot rolled steel. As an example, a hot rolled steel product may have a yield strength of 235 MPa. In comparison, a cold rolled steel product with the same chemical composition has a yield strength

Hot Rolled Steel vs. Cold Rolled Steel (Ultimate

The rolling of steel is mainly hot rolling, and cold rolling is usually used only for the production of steel with precise sizes such as small-sized section steel and thin plates. Wire Rod. The diameter of 5.5-40 mm, coil, all is hot rolled material. After cold drawing, it is cold drawing material.

The Differences Between Hot and Cold Rolled Steel

Compared to hot-rolled steel, cold-rolled steel has a nearly 20% increase in strength through the use of strain hardening. It’s through a series of breakdown, semi-finishing, sizing, semi-roughing, roughing, and finishing that cold-rolled steel shapes can be created. Cold-rolling steel allows for the creation of very precise shapes.

Cold rolled steel sheet is, essentially, hot rolled steel that has been further processed to increase its strength and strength-to-weight ratio. In general, cold rolled steel sheet can hold tighter tolerances than hot rolled when machined or otherwise fabricated, and provides a better overall surface finish.

In short, hot rolled steel is processed at the mill at high temperatures and that’s it. On the other hand, cold rolled steel is processed as hot roll, but once it has cooled to room temperature, it received additional processing for different benefits. Generally speaking, hot roll steel has a rougher surface, wider tolerances, and lower cost.

Cold vs Hot Rolling The main difference between cold rolled steel and hot rolled steel is the temperature at which they are formed. Cold rolled steel bar is formed at temperatures that are below that of its recrystallization temperature. In contrast, hot rolled steel is formed above its recrystallization temperature.

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.

The primary feature of cold reduction is to reduce the thickness of hot-rolled coils into thinner thicknesses that are not generally attainable in the hot rolled state. The cold reduction operation induces very high strains (work hardening) into the sheet; thus, the sheet not only becomes thinner, but also becomes much harder, less ductile, and
