What is Hot rolled stainless steel

In hot rolling, stainless steel is rolled and pressed above the recrystallization temperature. The temperature is about 1100°C. Heating above the recrystallization temperature can refine the grains of the microstructure and improve mechanical properties. At this point, stainless steel can be easily shaped and shaped.

Machining begins with a large rectangular sheet of metal called a billet. It is heated and rolled. The rolled metal is then exposed to high temperatures and passed continuously through rolls at high speed.

Hot rolling improves stainless steel properties such as toughness, ductility, formability and weldability. Stainless steel shrinks a bit as it cools. Tolerances and shape accuracy of hot rolled stainless steel products are affected. Scale removal can be done by sandblasting and pickling.

Because hot-rolled steel cools after processing, there is less control over its final shape, so hot-rolled stainless steel is recommended for applications where accuracy and size are not a major concern. Railroad tracks and construction projects often use hot rolled steel.
