What Is Scarfing?

Scarfing

Steel scarfing is a surface-cleaning process used to remove defects, impurities, or irregularities from the outer layer of steel, typically after casting or before further processing. It involved using an oxy-fuel torch or mechanical tools to cut or burn off the surface layer, exposing clean, defect-free metal underneath. Scarfing helps improve surface quality and is often used on steel slabs, billets, or blooms to prepare them for rolling or finishing processes, ensuring the final product meets strict quality standards.
