No.1 SS304 Stainless Steel Sheet Plate ASTM Hot Rolled 32mm Thickness 1219*2438 For Building

• Product Description

Hot working is more widely used compared to cold working because it needs less force and energy. It is used in compressive forming methods like rolling, metal extrusion, forging, etc.

Hot rolling takes place in temperatures above the material’s recrystallisation temperature. In case of steel, the temperatures rise above 1000°C.

The starting material is usually steel billets or slabs. First, they are heated above the aforementioned temperature. The next step is feeding them to the rolling machinery. Continuous rolling gives the desired final shape – a metal sheet (3 mm and upwards) or profile.

As it is easy to form metal in high temperatures without any extra delays, it is possible to produce it in larger quantities than cold rolled steel. This keeps the market price of hot rolled steel lower. The steel cools at room temperature. This is known as normalising. It changes the material’s microstructure in a way that results in increased ductility and toughness. Ductility is especially important when forming the material (e.g sheet metal bending) to give it the required shape for your needs.

Hot rolled steel, though, doesn’t have the best quality. It shrinks slightly during the cooling process. This leaves the metal with internal stresses. The results are non-uniform measurements and some distortions. The material’s dimensional tolerances can vary between 2…5%. Also, the surface has a scaly finish. This is a kind of oxide that forms at high temperatures, known as mill scale.

It is easy to identify hot rolled products by touching the surface because of the uneven finish but it is also lacking an oily film. With steel bars, the corners are rounded.
