hot rolled surface treatment alloy steel

Steel - Surface treating | BritannicaThe surface treatment of steel also begins during hot-rolling, because reheating conditions, in-line scale removal, rolling temperature, and cooling rate all determine the type and thickness of scale formed on the product, and this affects atmospheric corrosion, paintability, and subsequent scale-removal operations. Sometimes the final pass in hot-rolling generates specific surface patterns—for

Steel - Treating of steel | Britannica

Heat-treating In principle, heat-treating already takes place when steel is hot-rolled at a particular temperature and cooled afterward at a certain rate, but there are also many heat-treating process facilities specifically designed to produce particular microstructures and properties. The simplest heat-treating process is normalizing.Steel - Surface treating | BritannicaThe surface treatment of steel also begins during hot-rolling, because reheating conditions, in-line scale removal, rolling temperature, and cooling rate all determine the type and thickness of scale formed on the product, and this affects atmospheric corrosion, paintability, and subsequent scale-removal operations.
