Hot Rolled Steel
Hot rolled steel is a crucial component in modern industry and is known for its versatile applications and cost effectiveness. This type of steel is produced by heating steel slabs above their recrystallization temperature, typically over 1,700°F (about 927°C), then rolling them into desired shapes and sizes. The process involves passing the heated steel through rollers that gradually reduce its thickness while maintaining its ductility. The end product is characterized by a rough, scaly surface texture and less precise dimensional accuracy than cold rolled steel. However, the advantages of hot rolled steel lie in its low cost and its suitability for applications where precise shapes and tolerances are not critical, such as in the construction of rail tracks, I beams, and industrial machinery.
