Hot rolling process in stainless steel pipe fittings
Simply put, the process of rolling steel material after heating it to a temperature above the recrystallization temperature is called hot rolling. And below the recrystallization temperature, the process including rolling at room temperature is known as cold rolling. Hot rolled steel has good plasticity and is not difficult to form. After forming, the steel has no internal stress, which is all right with processing in the following procedures. For example, steel bars employed in construction, steel plates used for stamping, steel materials to be machined and heat-treated are all hot-rolled steel materials. Cold rolled steel has the characteristics of cold work hardening. Because of the good mechanical properties of cold rolling, many directly used sheets of steel use cold-rolled steel. Such as cold rolled steel bars, cold-rolled twisted steel bars, cold-rolled steel wires, cold-rolled steel plates, etc.
