The process can be done multiple times to achieve the desired thickness. This mechanical stress alters steel properties and increases strength by almost 20%. Steel billets are then pushed through rollers and undergo compression.
Once the steel is cooled below its recrystallization temperature, it now undergoes the cold rolling process. During this, the steel goes through significant change in its material characteristic.
The finished product is left to cool at room temperatures, also known as Annealing. This is done to temper the steel bars and improve strength. Steel at first undergoes the hot rolling process at extreme temperatures. Here we are going to discuss it in detail. It is much finer and has better material properties than its counterpart Hot Rolled Steel. Household and Kitchen appliances, cabinets and metal furniture, precise industrial equipment, Aerospace components, etc.Ĭold Rolled Steel- in simpler terms, is a type of steel processed at room temperature. Lower malleability, Hard to Machine.Ĭonstruction, Industrial machinery, Railroad Track, Pipe, Fittings, Agricultural Equipment, etc. Lesser strength, Residual stress after cooling.Įxpensive. Good Strength, Higher workability, i.e., can easily be shaped at high temperatures. And due to strain hardening, the strength of steel is further enhanced. It undergoes mechanical stress by passing it through pair of rollers. Hardening and other mechanical processes improve its strength and characteristics.Īfter HRS, the steel is cooled down. Steel is heated at extreme temperatures where the material properties are altered. Here are we have jotted down some key features of both types of steel.
It involves applying mechanical stress to steel by passing steel billets through the rollers at ambient temperature. Hot Rolled Steel is treated at a high temperature of 1700℉ (930℃), which alters its material properties.Ĭontrary to this Cold Rolling process comes after this and is done below the recrystallization temperature of steel. Hot and Cold Rolled steels are two distinctive types of metals because of how they are manufactured. Here we explore both the types, their manufacturing processes, differences, uses, and much more in detail! Hot Rolled Steel Vs. Each material has its own strengths and is best suited for specific applications. These are crucial components of the manufacturing industry, and each has unique benefits to offer. Hot and Cold Rolled steels are popular materials used in almost all the products we use in our daily lives.
