Steel Base Metal: Width Range 600-2000 mm, Elongation 25-40%

Component Specifications

Definition

Steel base metal refers to the raw steel material used as the foundational substrate in the production of cold rolled steel strips. This material undergoes cold rolling processes to achieve precise thickness, surface finish, and mechanical properties required for various industrial applications. It serves as the core structural element that determines the final strip's performance characteristics.

Working Principle

The steel base metal provides the fundamental metallic structure that is deformed through cold rolling processes below its recrystallization temperature. This plastic deformation increases strength through strain hardening while achieving precise dimensional tolerances and surface qualities. The material's crystalline structure is elongated and refined during rolling, enhancing mechanical properties without phase transformation.

Materials

Low-carbon steel (typically 0.05-0.25% carbon content), alloy steels with manganese, silicon, or micro-alloying elements. Common grades include SAE 1006, 1010, 1018 with controlled sulfur and phosphorus levels.
