Carbon steel scrap used as charge material for ordinary cacbon steel making. Classification and technical requirements

This standard establishes the classification system and technical specifications for scrap steel intended as raw material in the production of ordinary carbon steel. It defines the categorization criteria based on physical form, chemical composition limits, and impurity constraints to ensure suitability for melting processes. The document outlines requirements regarding the permissible levels of elements such as copper, tin, and lead, which may adversely affect the quality of the final steel product. It also specifies criteria for dimensional consistency, cleanliness, and the absence of non-ferrous inclusions or excessive moisture. These technical parameters are designed to facilitate the consistent integration of recycled steel materials into the manufacturing workflow, thereby supporting the optimization of production efficiency and material quality. By setting clear boundaries for different grades of scrap, the regulation aids manufacturers in selecting appropriate inputs that meet the necessary metallurgical standards for carbon steel fabrication without compromising structural integrity.
